Description

Technical Field

[0001] This application relates to the field of satellite positioning technology, and in particular to a data processing method and related apparatus. Background Technology

[0002] The Global Navigation Satellite System (GNSS) consists of the BeiDou Navigation Satellite System (BDS), the Global Positioning System (GPS), the GLONASS system, and the Galileo system.

[0003] Each satellite navigation system consists of multiple satellites, each of which can transmit signals to user equipment. User equipment can determine the orbital data of a satellite based on the navigation messages from each satellite. The navigation messages may include ephemeris data. However, the same satellite can generally exist on multiple frequencies. User equipment usually stores the ephemeris data from navigation messages sent through different frequencies separately and retrieves it separately. This results in significant storage resource overhead and power consumption for user equipment. Summary of the Invention

[0004] In view of this, this application provides a data processing method and related apparatus that can convert different types of ephemeris data into the same type for use and storage, greatly reducing storage resource overhead and power consumption overhead.

[0005] In a first aspect, embodiments of this application provide a data processing method, the method comprising:

[0006] Acquire the first ephemeris data of the target satellite. The first ephemeris data is of a first type. The first type is used to indicate the definition of each first ephemeris parameter in the first ephemeris data and the first format of each first ephemeris parameter.

[0007] If the first type of the first ephemeris data does not belong to the target type, the first ephemeris data is converted into target ephemeris data to update the current ephemeris data. The target type is used to indicate the definition of each target ephemeris parameter in the target ephemeris data and the target format of each target ephemeris parameter.

[0008] Secondly, embodiments of this application provide a data processing apparatus, the apparatus comprising:

[0009] An acquisition unit is used to acquire first ephemeris data of a target satellite. The first ephemeris data is of a first type. The first type is used to indicate the definition of each first ephemeris parameter in the first ephemeris data and the first format of each first ephemeris parameter.

[0010] The processing unit is configured to convert the first ephemeris data into target ephemeris data to update the current ephemeris data if the first type of the first ephemeris data does not belong to the target type. The target type is used to indicate the definition of each target ephemeris parameter in the target ephemeris data and the target format of each target ephemeris parameter.

[0011] Thirdly, embodiments of this application provide an electronic device, including a processor, a memory, a communication interface, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processor, and the programs include instructions for performing steps in any method of the first aspect of this application.

[0012] Fourthly, embodiments of this application provide a computer-readable storage medium storing a computer program for electronic data interchange, wherein the computer program causes a computer to perform some or all of the steps described in any method of the first aspect of this application.

[0013] Fifthly, embodiments of this application provide a computer program product, wherein the computer program product includes a non-transitory computer-readable storage medium storing a computer program operable to cause a computer to perform some or all of the steps described in any method of the first aspect of this application. The computer program product may be a software installation package.

[0014] As can be seen, through the above data processing method and related apparatus, firstly, the first ephemeris data of the target satellite is acquired. This first ephemeris data is of a first type, which indicates the definition of each first ephemeris parameter and the first format of each first ephemeris parameter. If the first type of the first ephemeris data does not belong to the target type, the first ephemeris data is converted to target ephemeris data to update the current ephemeris data. The target type indicates the definition of each target ephemeris parameter and the target format of each target ephemeris parameter. This allows ephemeris data to be stored and retrieved in a unified type, significantly reducing storage resource overhead and power consumption. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] The following is a brief introduction to the relevant terminology used in this application.

[0029] Satellite ephemeris is information describing the orbit of a satellite. In other words, satellite ephemeris is a set of orbital parameters and their variability corresponding to a specific moment. With satellite ephemeris, the satellite's position and velocity at any given time can be calculated. In this embodiment, ephemeris data refers to broadcast ephemeris data, which typically includes Keplerian orbital parameters relative to a reference epoch and necessary orbital perturbation correction parameters.

[0030] Currently, ephemeris data at different frequencies have different data types. For example, the broadcast ephemeris at the first frequency has 16 parameters, while the broadcast ephemeris at the second frequency has 19 parameters. The parameters of the broadcast ephemeris at the first frequency include parameters describing the satellite's orbital characteristic 'a', while the parameters of the broadcast ephemeris at the second frequency do not include parameters describing the satellite's orbital characteristic 'a', which will not be elaborated upon here. For ephemeris data at different frequencies of the same satellite, they are generally stored separately, and the application layer develops and maintains the corresponding calculation logic for the ephemeris data at different frequencies. That is, the parameters of the broadcast ephemeris at the first frequency are stored in region 'a'. If the parameters of the broadcast ephemeris at the second frequency are obtained, a new region 'b' is created to store the parameters of the broadcast ephemeris at the second frequency. At the same time, the calculation logic for the parameters of the broadcast ephemeris at the first frequency and the calculation logic for the parameters of the broadcast ephemeris at the second frequency are developed and maintained separately. Since there are often many overlapping parts between ephemeris data at different frequencies, the current method consumes a lot of storage resources, and the power consumption of developing and maintaining ephemeris data at different frequencies is also relatively high.

[0031] To address the aforementioned issues, this application provides a data processing method and related apparatus that can convert ephemeris data at different frequencies into ephemeris data of the same type. This eliminates the need to store ephemeris data at different frequencies separately, and also eliminates the need to develop and maintain separate computational logic for ephemeris data at different frequencies, thereby significantly reducing storage resource overhead and power consumption.

[0032] The following is combined with Figure 1 The application scenario of a data processing method in the embodiments of this application will be described. Figure 1 The following is an application scenario diagram of a data processing method provided in an embodiment of this application, including a terminal device 110 and a satellite navigation system 120. The satellite navigation system 120 may include multiple satellites 121. The terminal device 110 can communicate with any satellite 121 to obtain the ephemeris data of the corresponding satellite 121, and then determine the orbit data of the satellite 121 based on the ephemeris data.

[0033] In this application embodiment, the terminal device 110 can be a device with transceiver functions, and may also be referred to as a terminal, user equipment (UE), remote terminal equipment (relay UE), relay equipment (relay UE), access terminal equipment, user unit, user station, mobile station, mobile station, remote station, mobile device, user terminal equipment, smart terminal equipment, wireless communication equipment, user agent, or user device. It should be noted that a relay equipment is a terminal device capable of providing relay forwarding services to other terminal devices (including remote terminal devices).

[0034] For example, terminal device 110 can be a mobile phone, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in autonomous driving, wireless terminal device in remote medical care, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, or wireless terminal device in smart home, etc.

[0035] For example, terminal device 110 can also be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal device in next-generation communication systems (such as NR communication systems, 6G communication systems), or terminal device in a future public land mobile network (PLMN), etc., without specific limitations.

[0036] In some possible implementations, terminal device 110 may include means for wireless communication functionality, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, and may also include other discrete devices.

[0037] In this embodiment, any one of the satellites 121 can provide wireless coverage services to the terminal device 110, such as allocating wireless resources to the access terminal and providing reliable wireless transmission protocols and data encryption protocols. These functions can be achieved through base stations or partial base station functions deployed on the satellite 121.

[0038] There is also a wireless link between satellites 121, which enables signaling interaction and user data transmission between satellites.

[0039] Specifically, terminal device 110 can acquire ephemeris data of any satellite 121, and when the type of ephemeris data does not belong to a specific type, it can convert the ephemeris data into ephemeris data of a specific type to update the current ephemeris data. In this way, ephemeris data of different frequencies of the same satellite can be stored in a unified data structure, which greatly reduces storage resource overhead. At the same time, only one computing logic needs to be developed and maintained, which greatly reduces power consumption.

[0040] The following is combined with Figure 2 The electronic devices in the embodiments of this application will be described. Figure 2 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application, such as... Figure 2 As shown, the electronic device includes one or more application processors 220, a memory 230, a communication module 240, and one or more programs 231. The application processor 220 is communicatively connected to the memory 230 and the communication module 240 via an internal communication bus.

[0041] The one or more programs 231 are stored in the memory 230 and configured to be executed by the application processor 220. The one or more programs 231 include instructions for performing any step in the above method embodiments.

[0042] The application processor 220 may be, for example, a central processing unit (CPU), a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, transistor logic devices, hardware components, or any combination thereof. It can implement or execute the various exemplary logic blocks, cells, and circuits described in conjunction with the disclosure of this application. The application processor 220 may also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of a DSP and a microprocessor, etc. The communication unit may be a communication module 240, a transceiver, a transceiver circuit, etc., and the storage unit may be a memory 230.

[0043] The memory 230 can be volatile memory or non-volatile memory, or may include both. The non-volatile memory can be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), or flash memory. The volatile memory can be random access memory (RAM), which is used as an external cache. By way of example, but not limitation, many forms of random access memory (RAM) are available, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate synchronous DRAM (DDR SDRAM), enhanced synchronous DRAM (ESDRAM), synchronous linked DRAM (SLDRAM), and direct rambus RAM (DR RAM).

[0044] It is understood that the electronic device 20 may include more or fewer structural elements than those shown in the above structural block diagram, such as a power module, physical buttons, a Wi-Fi module, a speaker, a Bluetooth module, a sensor, a display module, etc., which are not limited herein. It is understood that the electronic device 20 may be the terminal device in the embodiments of this application.

[0045] The following is combined with Figure 3 One data processing method from an embodiment of this application will be described. Figure 3 This application provides a schematic flowchart of a data processing method, which specifically includes the following steps:

[0046] Step 301: Obtain the first ephemeris data of the target satellite.

[0047] The first ephemeris data is of a first type. The first type is used to indicate the definition of each first ephemeris parameter in the first ephemeris data and the first format of each first ephemeris parameter. It can be understood that the first ephemeris data includes multiple first ephemeris parameters, and the first type of the first ephemeris data corresponds to the frequency of the target satellite.

[0048] Specifically, the first ephemeris data of the target satellite can be determined by receiving and parsing the navigation message of the target satellite. It should be noted that the target satellite can send navigation messages multiple times, and each navigation message will carry ephemeris data. The terminal device can parse each navigation message sent to obtain the first ephemeris data.

[0049] For example, if the target satellite has two frequency points, one of which corresponds to the Legacy Navigation (LNAV) type and the other to the Civil Navigation (CNAV) type, then the first type of the first ephemeris data obtained at this time can be either LNAV type or CNAV type.

[0050] In one possible embodiment, the definition of the first ephemeris parameter of type LNAV and the format of each first ephemeris parameter are shown in Table 1, as follows:

[0051] Table 1

[0052]

[0053] In one possible embodiment, the definition of the first ephemeris parameter of the CNAV type and the format of each first ephemeris parameter are shown in Table 2, as follows:

[0054] Table 2

[0055]

[0056]

[0057] It is evident that CNAV type first ephemeris data and LNAV type first ephemeris data contain both the same and different ephemeris parameters, and the number of ephemeris parameters included in different types of ephemeris data is also not the same.

[0058] It can be understood that the first type is any one of all types corresponding to all frequency points of the target satellite, and the first format is the arrangement of parameters, symbol representation, and other formats under the first type. Each first ephemeris parameter has its physical definition, and the orbital data of the target satellite can be determined through the first ephemeris data.

[0059] Obtaining the first ephemeris data of the target satellite can provide a reference for subsequent data processing.

[0060] Step 302: If the first type of the first ephemeris data does not belong to the target type, then convert the first ephemeris data into the target ephemeris data to update the current ephemeris data.

[0061] The target type is used to indicate the definition of each target ephemeris parameter in the target ephemeris data and the target format of each target ephemeris parameter. It can be understood that the target type is any one of all types corresponding to all frequency points of the target satellite, and the target format refers to the arrangement, symbol representation, and other formats of the parameters under the target type. For example, when the target satellite corresponds to both CNAV and LNAV types, the target type can be either LNAV or CNAV.

[0062] Specifically, the first definition set, the second definition set, the third definition set, and the fourth definition set can be determined by comparing the similarities and differences between the first type and the target type. In the first definition set, each first definition is the same as the definition of any target ephemeris parameter. In the second definition set, any second definition is different from the definition of any first ephemeris parameter and they do not have a derivation relationship. In the third definition set, any third definition is different from the definition of any target ephemeris parameter. In the fourth definition set, any fourth definition is different from the definition of any first ephemeris parameter but they have a derivation relationship.

[0063] Specifically, when determining the first definition set, we can compare the similarities between the first type and the target type. The definitions of the ephemeris parameters of the first type that are the same as the definitions of the ephemeris parameters of the target type are grouped into the first definition set. In this way, each first definition belongs to the definition of the target ephemeris parameter of any target type. This is equivalent to the first definition set being a proper subset of the set of ephemeris parameter definitions of the target type.

[0064] To make it more intuitive, we will use LNAV and CNAV types as examples, as shown in Table 3 below:

[0065] Table 3

[0066]

[0067] Table 3 lists the ephemeris parameters that have the same definition for LNAV and CNAV types. These parameters constitute the first definition set. Since only the format differs, the first format of each first ephemeris parameter that has the same definition as each of the first parameters can be converted to the target format to obtain the first target ephemeris parameter. For example, if the first type of the first ephemeris parameter is LNAV and the target type is CNAV, then according to Table 3, the first ephemeris parameter M0 can be converted to M... 0-nThis can be done by converting all the first ephemeris parameters in LNAV format in Table 3 to CNAV format to obtain the first target ephemeris parameters. If the first type of the first ephemeris parameter is CNAV and the target type is LNAV, then converting all the first ephemeris parameters in CNAV format in Table 3 to LNAV format will obtain the first target ephemeris parameters. This will not be elaborated on here. In this way, the accurate converted first target ephemeris parameters can be obtained.

[0068] Specifically, when determining the second set of definitions, we can compare the differences between the first type and the target type. We can form the second set of definitions by combining the definitions of the ephemeris parameters of the first type that are different from and have no derivation relationship with the definitions of the ephemeris parameters of the target type. In this way, each second definition does not belong to any definition of the first ephemeris parameter of the first type, but each second definition belongs to the definition of the target ephemeris parameter of the target type. This is equivalent to the second set of definitions being a proper subset of the set of definitions of the target ephemeris parameters of the target type.

[0069] For a clearer understanding, we will use an example where the first type is LNAV and the target type is CNAV, as shown in Table 4 below:

[0070] Table 4

[0071]

[0072] Table 4 lists ephemeris parameters unique to the CNAV type compared to the LNAV type, which cannot be derived from the LNAV type ephemeris parameters. These parameters constitute a second set of definitions. Each second target ephemeris parameter with the same definition can be set to zero. For example, if the first type of the first ephemeris parameter is LNAV and the target type is CNAV, then according to Table 4, the first ephemeris data does not contain first ephemeris parameters describing the "rate of change of the deviation of the satellite's average angular velocity" and the "rate of change of the satellite's semi-major axis." These two second target ephemeris parameters can be set to zero, i.e., assigned a value of 0. In this way, accurate second target ephemeris parameters can be obtained.

[0073] It should be noted that whether there is a derivation relationship between different defined ephemeris parameters can be determined by whether there is a relevant formula. For example, if there is no formula that allows ephemeris parameter a to be combined with preset parameters to obtain ephemeris parameter b, then it can be considered that there is no derivation relationship between ephemeris parameter a and ephemeris parameter b. If there is a formula that allows ephemeris parameter a to be combined with preset parameters to obtain ephemeris parameter b, then it can be considered that there is a derivation relationship between ephemeris parameter a and ephemeris parameter b.

[0074] Specifically, when determining the third definition set, the differences between the first type and the target type can be compared. The definitions of ephemeris parameters that belong to the first type can be grouped into the third definition set. In this way, each third definition does not belong to the definition of the target ephemeris parameter of any target type, but each third definition belongs to the definition of the first ephemeris parameter of the first type. It is equivalent to the third definition set being a proper subset of the set of the first ephemeris parameter definitions of the first type. It can be understood that the first definition set and the third definition set can constitute the set of all first ephemeris parameter definitions.

[0075] For a clearer understanding, we will use an example where the first type is LNAV and the target type is CNAV, as shown in Table 5 below:

[0076] Table 5

[0077]

[0078] Table 5 lists the ephemeris parameters specific to the LNAV type. The definitions of these parameters constitute a third set of definitions. Each first ephemeris parameter with the same definition as each of the third definitions can be deleted. For example, if the first type of the first ephemeris parameter is LNAV and the target type is CNAV, then according to Table 5, since the target ephemeris data does not contain ephemeris parameters describing "rate of change of right ascension of the ascending node" and "square root of the semi-major axis of the satellite orbit", when converting the first ephemeris parameters to the target ephemeris data, it is necessary to delete the first ephemeris parameter defined as "rate of change of right ascension of the ascending node" and the first ephemeris parameter defined as "square root of the semi-major axis of the satellite orbit". In this way, the interference of irrelevant ephemeris parameters can be eliminated, and accurate target ephemeris data can be obtained.

[0079] Specifically, when determining the fourth definition set, we can compare the differences between the first type and the target type. The definitions of the ephemeris parameters of the first type that are different from the definitions of the ephemeris parameters of the target type but have a derivation relationship are grouped into the fourth definition set. In this way, each fourth definition does not belong to any definition of the first ephemeris parameter of the first type but has a derivation relationship. At the same time, each fourth definition belongs to the definition of the target ephemeris parameter of the target type. It is equivalent to the fourth definition set being a proper subset of the set of the definitions of the target ephemeris parameters of the target type. It can be understood that the first definition set, the second definition set, and the third definition set can constitute the set of all definitions of the target ephemeris parameters.

[0080] For a clearer understanding, we will use an example where the first type is LNAV and the target type is CNAV, as shown in Table 6 below:

[0081] Table 6

[0082]

[0083] Table 6 lists ephemeris parameters specific to the CNAV type, but these can be derived from the ephemeris parameters of the LNAV type. The derivation relationships are shown in the table. Each third target ephemeris parameter defined in the same way as each fourth definition can be determined based on these derivation relationships. For example, if the first type of the first ephemeris parameter is LNAV and the target type is CNAV, then according to Table 5, the third target ephemeris parameter describing the "deviation between the rate of change of right ascension of the ascending node and the reference value of the rate of change of right ascension of the ascending node" in the target ephemeris data can be obtained from the first ephemeris data. The third target ephemeris parameter, describing the "rate of change of right ascension of the ascending node," is obtained by subtracting the "reference value of the rate of change of right ascension of the ascending node." Similarly, the third target ephemeris parameter, describing the "deviation of the semi-major axis of the satellite's orbit," can be obtained by subtracting the "reference value of the semi-major axis of the satellite's orbit" from the square of the first ephemeris parameter describing the "square root of the semi-major axis of the satellite's orbit." It should be noted that both the "reference value of the rate of change of right ascension of the ascending node" and the "reference value of the semi-major axis of the satellite's orbit" are preset parameters; their values ​​are known and fixed, and do not require measurement. In this way, accurate third target ephemeris parameters can be obtained.

[0084] Finally, the target ephemeris data can be determined based on the first target ephemeris parameter, the second target ephemeris parameter, and the third target ephemeris parameter to update the current ephemeris data.

[0085] It should be noted that the first set of definitions, the second set of definitions, the third set of definitions, and the fourth set of definitions can be empty sets. No processing is required for empty sets.

[0086] As can be seen, the above data processing method can convert ephemeris data of different frequencies into the same type of ephemeris data, eliminating the need to store ephemeris data of different frequencies separately, and also eliminating the need to develop and maintain the calculation logic of ephemeris data of different frequencies separately, which greatly reduces storage resource overhead and power consumption overhead.

[0087] The following is combined with Figure 4 Another data processing method in the embodiments of this application will be described. Figure 4 A flowchart illustrating another data processing method provided in this application embodiment specifically includes the following steps:

[0088] Step 401: Determine the target type.

[0089] In one possible embodiment, a second type of the first ephemeris data of the acquired target satellite can be determined, and then the second type can be determined as the target type. For example, if the first ephemeris data is of type CNAV, then the target type can be determined as type CNAV. This allows for faster determination of the target type and ensures that the determined target type is compatible with the target satellite.

[0090] In one possible embodiment, the types of ephemeris data corresponding to a first frequency point and a second frequency point of the target satellite can be determined. Then, a first preset ephemeris data is set for the type corresponding to the first frequency point, and a second preset ephemeris data is set for the type corresponding to the second frequency point. The first preset ephemeris data may include multiple first preset ephemeris parameters, the number, format, and definition of which are indicated by the type corresponding to the first frequency point. The second preset ephemeris data may include multiple second preset ephemeris parameters, the number, format, and definition of which are indicated by the type corresponding to the second frequency point. Next, the satellite orbit data before the first conversion can be determined based on the first preset ephemeris data. The specific calculation process can be found in existing satellite positioning algorithms and will not be elaborated here. Similarly, the satellite orbit data before the second conversion can be determined based on the second preset ephemeris data. Then, the first preset ephemeris data is converted to the type corresponding to the second frequency point, and the satellite orbit data after the first conversion is determined. Similarly, the second preset ephemeris data is converted to the type corresponding to the first frequency point, and the satellite orbit data after the second conversion is determined. The conversion methods described above can be found in [reference needed]. Figure 3 The description of step 302 is omitted here. Finally, a first error is determined based on the first pre-conversion satellite orbit data and the first post-conversion satellite orbit data, and a second error is determined based on the second pre-conversion satellite orbit data and the second post-conversion satellite orbit data. The first pre-conversion satellite orbit data can be used as a standard reference, and the difference between the first post-conversion satellite orbit data and the first pre-conversion satellite orbit data is positively correlated with the first error. Similarly, the second pre-conversion satellite orbit data can be used as a standard reference, and the difference between the second post-conversion satellite orbit data and the second pre-conversion satellite orbit data is positively correlated with the second error. Finally, the first error and the second error are compared. If the first error is greater than the second error, the type corresponding to the first frequency point is determined as the target type; if the second error is greater than the first error, the type corresponding to the second frequency point is determined as the target type. This allows the type with the smaller post-conversion error to be used as the target type, improving the accuracy of satellite orbit calculation.

[0091] In one possible embodiment, the first error and the second error need to be within the error threshold range. If the first error and the second error exceed the error threshold range, the type corresponding to the first frequency point and the type of the second frequency point will not be determined as the target type to prevent the error from being too large after data conversion.

[0092] It is evident that by determining the target type, a more suitable target type can be identified, thereby improving the accuracy of satellite orbit calculations.

[0093] Step 402: Obtain the first ephemeris data of the target satellite.

[0094] Step 403: Determine the difference data between the first type and the target type.

[0095] The difference data may include at least one of the following: the number of format differences, the number of difference definitions with derivation relationships, the derivation error coefficient of each difference definition with derivation relationships, and the number of difference definitions without derivation relationships. The derivation error coefficient can be determined by comparing the difference between the pre-conversion satellite orbit data corresponding to the pre-conversion ephemeris data of the first type and the post-conversion satellite orbit data corresponding to the post-conversion ephemeris data of the target type. The larger the derivation error coefficient, the larger the error.

[0096] Step 404: If the difference data does not meet the preset difference conditions, then reacquire the first ephemeris data until the difference data meets the preset difference conditions.

[0097] The preset difference conditions include at least one of the following: a threshold for the number of format differences, a threshold for the number of difference definitions with derivation relationships, a threshold for the derivation error coefficient of each difference definition with a derivation relationship, and a threshold for the number of difference definitions without derivation relationships.

[0098] In this way, first ephemeris data that differs too much from the target type can be excluded, thus improving the accuracy of subsequent satellite orbit calculations.

[0099] Step 405: If the first type of the first ephemeris data does not belong to the target type, then convert the first ephemeris data into the target ephemeris data to update the current ephemeris data.

[0100] Step 406: If the first type belongs to the target type, then determine the first ephemeris data as the target ephemeris data to update the current ephemeris data.

[0101] Step 407: Determine the parameter fitting algorithm corresponding to the current ephemeris data.

[0102] Different ephemeris data have corresponding parameter fitting algorithms, such as the parameter fitting algorithm for 16 ephemeris parameters, the parameter fitting algorithm for 19 ephemeris parameters, etc., which will not be elaborated here.

[0103] Step 408: Determine satellite orbit data based on the parameter fitting algorithm and the ephemeris parameters of each target.

[0104] As can be seen, the above data processing methods can significantly reduce storage resource consumption and power consumption while ensuring that the accuracy of satellite orbit calculation is not significantly lost.

[0106] The above primarily describes the solutions of the embodiments of this application from the perspective of the method execution process. It is understood that, in order to achieve the above functions, the electronic device includes corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, in conjunction with the units and algorithm steps of the various examples described in the embodiments provided herein, this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0107] This application embodiment can divide the electronic device into functional units according to the above method example. For example, each function can be divided into a separate functional unit, or two or more functions can be integrated into one processing unit. The integrated unit can be implemented in hardware or as a software functional unit.
