[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The following is an introduction to the relevant terms involved in this application.

[0029] Satellite ephemeris is information describing the orbit of a satellite. It can also be said that satellite ephemeris is a set of orbital parameters and their rates of change corresponding to a certain moment. With satellite ephemeris, the satellite position and velocity at any moment can be calculated. In the embodiment of the present application, ephemeris data refers to broadcast ephemeris data, which usually includes Kepler orbital parameters and necessary orbital perturbation correction parameters relative to a certain reference epoch.

[0030] At present, the data types of ephemeris data at different frequencies are different. For example, the parameters of the broadcast ephemeris at the first frequency are 16, and the parameters of the broadcast ephemeris at the second frequency are 19. The parameters of the broadcast ephemeris at the first frequency include the parameters describing the orbital characteristics a of the satellite, while the parameters of the broadcast ephemeris at the second frequency do not include the parameters describing the orbital characteristics a of the satellite, which will not be described in detail here. For the ephemeris data at different frequencies of the same satellite, they are generally stored separately, and the application layer will develop and maintain the corresponding calculation logic of the ephemeris data at different frequencies, that is, the parameters of the broadcast ephemeris at the first frequency are stored in area a. If the parameters of the broadcast ephemeris at the second frequency are obtained, then a new area b will be created to store the parameters of the broadcast ephemeris at the second frequency. At the same time, the calculation logic of the parameters of the broadcast ephemeris at the first frequency and the calculation logic of the parameters of the broadcast ephemeris at the second frequency will be developed and maintained respectively. Since there are often many repeated parts between the ephemeris data at different frequencies, the current method consumes more storage resources, and the power consumption is also large when developing and maintaining the ephemeris data at different frequencies.

[0031] To solve the above problems, the embodiments of the present application provide a data processing method and related devices, which can convert ephemeris data of different frequencies into ephemeris data of the same type. There is no need to store the ephemeris data of different frequencies separately, and there is no need to develop and maintain the calculation logic of the ephemeris data of different frequencies separately, which greatly reduces the storage resource overhead and power consumption overhead.

[0032] Combine the following Figure 1 An application scenario of a data processing method in an embodiment of the present application is described. Figure 1 An application scenario diagram of a data processing method provided for an embodiment of the present application includes a terminal device 110 and a satellite navigation system 120, wherein the satellite navigation system 120 may include multiple satellites 121, and the terminal device 110 may communicate with any satellite 121 to obtain the ephemeris data of the corresponding satellite 121, and then determine the orbital data of the satellite 121 based on the ephemeris data.

[0033] The terminal device 110 involved in the embodiment of the present application may be a device with transceiver functions, which may also be referred to as a terminal, user equipment (UE), remote terminal equipment (remote UE), relay equipment (relay UE), access terminal equipment, user unit, user station, mobile station, mobile station, remote station, mobile device, user terminal equipment, intelligent terminal equipment, wireless communication equipment, user agent or user device. It should be noted that a relay device is a terminal device that can provide relay forwarding services for other terminal devices (including remote terminal devices).

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

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

[0036] In some possible implementations, the terminal device 110 may include a device with wireless communication functions, 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] Among them, any satellite 121 in the embodiment of the present application can provide wireless coverage services for the terminal device 110, such as scheduling wireless resources to the access terminal, providing reliable wireless transmission protocols and data encryption protocols, etc. The above functions can be implemented by deploying base stations or part of base station functions on the satellite 121.

[0038] There are also wireless links between the satellites 121, which can realize signaling interaction and user data transmission between satellites.

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

[0040] Combine the following Figure 2 The electronic device in the embodiment of the present application is described. Figure 2 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application is shown in FIG. 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 with 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 executing any step in the method embodiment.

[0042] Among them, the application processor 220 can be, for example, a central processing unit (CPU), a general 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 various exemplary logic blocks, units and circuits described in conjunction with the disclosure of this application. The application processor 220 can also be a combination that implements computing functions, such as a combination of one or more microprocessors, a combination of DSP and microprocessors, and the like. The communication unit can be a communication module 240, a transceiver, a transceiver circuit, etc., and the storage unit can be a memory 230.

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

[0044] It is understandable that the electronic device 20 may include more or fewer structural elements than those in the above structural block diagram, for example, including a power module, a physical button, a Wi-Fi module, a speaker, a Bluetooth module, a sensor, a display module, etc., which are not limited here. It is understandable that the electronic device 20 may be a terminal device in the embodiment of the present application.

[0045] Combine the following Figure 3 A data processing method in an embodiment of the present application is described. Figure 3 A flowchart of a data processing method provided in an embodiment of the present application specifically includes the following steps:

[0046] Step 301, obtaining first ephemeris data of a target satellite.

[0047] Among them, the first ephemeris data is of the first type, and 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] Among them, the first ephemeris data of the target satellite can be determined by receiving the navigation message of the target satellite and parsing it. It should be noted that the target satellite can send navigation messages multiple times, and each navigation message sent will carry ephemeris data. The terminal device can parse the navigation message sent each time to obtain the first ephemeris data.

[0049] For example, if the target satellite has two frequencies, one of which corresponds to the legacy navigation (LNAV) type, and the other corresponds to the civil navigation (CNAV) type, then the first type of the first ephemeris data acquired at this time can be the LNAV type or the CNAV type.

[0050] In a possible embodiment, the definition of the first ephemeris parameter of the LNAV type and the format of each first ephemeris parameter refer to Table 1, as shown below:

[0051] Table 1

[0052]

[0053] In a possible embodiment, the definition of the first ephemeris parameter of the CNAV type and the format of each first ephemeris parameter refer to Table 2, as shown below:

[0054] Table 2

[0055]

[0056]

[0057] It can be seen that the CNAV type first ephemeris data and the LNAV type first ephemeris data have ephemeris parameters with the same definition and ephemeris parameters with different definitions, and the number of ephemeris parameters included in different types of ephemeris data is also different.

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

[0059] By obtaining the first ephemeris data of the target satellite, a reference can be provided for subsequent data processing.

[0060] Step 302: If the first type of the first ephemeris data does not belong to the target type, convert the first ephemeris data into target ephemeris data to update 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 is the format of the arrangement and symbol representation of the parameters under the target type. For example, when the target satellite corresponds to the CNAV type and the LNAV type, the target type can be the LNAV type or the CNAV type.

[0062] Among them, the first definition set, the second definition set, the third definition set and the fourth definition set can be determined by first comparing the similarities and differences between the first type and the target type, each first definition in the first definition set is the same as the definition of any target ephemeris parameter, any second definition in the second definition set is different from the definition of any first ephemeris parameter and has no derivation relationship, any third definition in the third definition set is different from the definition of any target ephemeris parameter, and any fourth definition in the fourth definition set is different from the definition of any first ephemeris parameter but has a derivation relationship.

[0063] Specifically, when determining the first definition set, the similarities between the first type and the target type can be compared, and 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 can be combined into the first definition set. In this way, each first definition belongs to the definition of the target ephemeris parameters of any target type, which is equivalent to the first definition set being a true subset of the set consisting of the definitions of the ephemeris parameters of the target type.

[0064] For a more intuitive understanding, LNAV type and CNAV type are used as examples, see Table 3, as shown below:

[0065] Table 3

[0066]

[0067] Table 3 defines the same ephemeris parameters for the LNAV type ephemeris parameters and the CNAV type ephemeris parameters. The definitions of these parameters constitute a first definition set. Since only the format is different, the first format of each first ephemeris parameter that is the same as the definition of each first parameter can be converted to the target format to obtain a first target ephemeris parameter. For example, 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-nIt can be expressed that, and so on, the first ephemeris parameters in the LNAV format in Table 3 can be converted into the 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, the first ephemeris parameters in the CNAV format in Table 3 can be converted into the LNAV format to obtain the first target ephemeris parameters, which will not be repeated here. In this way, the accurate converted first target ephemeris parameters can be obtained.

[0068] Specifically, when determining the second definition set, the differences between the first type and the target type can be compared, and the definitions of the ephemeris parameters of the first type that are different from the definitions of the ephemeris parameters of the target type and have no derivation relationship are formed into a second definition set. In this way, each second definition does not belong to the definition of any first ephemeris parameter of the first type, but each second definition belongs to the definition of the target ephemeris parameters of the target type, which is equivalent to the second definition set being a proper subset of the set consisting of the definitions of the target ephemeris parameters of the target type.

[0069] For a more intuitive purpose, an example is given here in which the first type is an LNAV type and the target type is a CNAV type, as shown in Table 4:

[0070] Table 4

[0071]

[0072] Table 4 shows the ephemeris parameters that are unique to the CNAV type compared to the LNAV type and cannot be derived from the ephemeris parameters of the LNAV type. The definition of this part of the parameters constitutes a second definition set, and each second target ephemeris parameter with the same definition as each second definition can be set to zero. For example, the first type of the first ephemeris parameter is LNAV, and the target type is CNAV. Then, according to Table 4, the first ephemeris parameter describing the "rate of change of the deviation of the average angular velocity of the satellite" and the "rate of change of the semi-major axis of the satellite orbit" does not exist in the first ephemeris data. The two second target ephemeris parameters can be set to zero, that is, the value of the two second target ephemeris parameters is assigned to 0, so that 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, 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, 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, and the definitions of the ephemeris parameters that are exclusive to the first type can be grouped into a third definition set. In this way, each third definition does not belong to the definition of the target ephemeris parameters of any target type, but each third definition belongs to the definition of the first ephemeris parameters of the first type, which is equivalent to the third definition set being a true subset of the set composed of the definitions of the first ephemeris parameters of the first type. It can be understood that the first definition set and the third definition set can constitute a set of definitions of all first ephemeris parameters.

[0075] For a more intuitive purpose, an example is given here in which the first type is an LNAV type and the target type is a CNAV type, as shown in Table 5:

[0076] Table 5

[0077]

[0078] Table 5 is the ephemeris parameters specific to the LNAV type. The definitions of this part of parameters constitute a third definition set. Each first ephemeris parameter with the same definition as each third definition can be deleted. For example, 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 describe the ephemeris parameters of "the rate of change of right ascension of the ascending node" and "the square root of the semi-major axis of the satellite orbit", when the first ephemeris parameter is converted into the target ephemeris data, it is necessary to delete the first ephemeris parameter with the parameter definition of "the rate of change of right ascension of the ascending node" and the first ephemeris parameter with the parameter definition of "the square root of the semi-major axis of the satellite orbit". In this way, the interference of irrelevant ephemeris parameters can be eliminated to obtain accurate target ephemeris data.

[0079] Specifically, when determining the fourth definition set, the differences between the first type and the target type can be compared, and the definitions of the ephemeris parameters of the first type that are different from the definitions of the ephemeris parameters of the target type and have a derivation relationship are formed into a fourth definition set. In this way, each fourth definition does not belong to the definition of any 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, which is equivalent to the fourth definition set being a true subset of the set constituted by 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 a set of definitions of all target ephemeris parameters.

[0080] For a more intuitive purpose, an example is given here in which the first type is an LNAV type and the target type is a CNAV type, as shown in Table 6:

[0081] Table 6

[0082]

[0083] Table 6 is the ephemeris parameter that is exclusive to the CNAV type, but it can be obtained by deriving the ephemeris parameter of the LNAV type. The derivation relationship is shown in the table. Each third target ephemeris parameter with the same definition as each fourth definition can be determined according to the derivation relationship. For example, 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 of the right ascension change rate of the ascending node from the reference value of the right ascension change rate of the ascending node" in the target ephemeris data can be obtained by describing the third target ephemeris parameter in the first ephemeris data. The third target ephemeris parameter describing the "deviation of the semi-major axis of the satellite orbit" in the target ephemeris data can be obtained by subtracting the "reference value of the semi-major axis of the satellite orbit" from the first ephemeris parameter describing the "square root of the semi-major axis of the satellite orbit" in the first ephemeris data. It should be noted that the above-mentioned "reference value of the rate of change of the right ascension of the ascending node" and "reference value of the semi-major axis of the satellite orbit" are both preset parameters, and their values ​​are known fixed values ​​and can be obtained without measurement. In this way, an accurate third target ephemeris parameter can be obtained.

[0084] Finally, the target ephemeris data may be determined according to 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 definition set, the second definition set, the third definition set and the fourth definition set may be empty sets, and no processing is performed on the empty sets.

[0086] It can be seen that through the above data processing method, the ephemeris data of different frequencies can be converted into the same type of ephemeris data. There is no need to store the ephemeris data of different frequencies separately, and there is no need to develop and maintain the calculation logic of the ephemeris data of different frequencies separately, which greatly reduces the storage resource overhead and power consumption overhead.

[0087] Combine the following Figure 4 Another data processing method in the embodiment of the present application is described. Figure 4 A flowchart of another data processing method provided in an embodiment of the present application specifically includes the following steps:

[0088] Step 401, determine the target type.

[0089] In a possible embodiment, the 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 CNAV type, then the target type can be determined as CNAV type. In this way, the target type can be determined more quickly and the determined target type can be adapted to the target satellite.

[0090] In a possible embodiment, the type of ephemeris data corresponding to the first frequency point of the target satellite and the type of ephemeris data corresponding to the second frequency point can be determined, and then the first preset ephemeris data is set for the type corresponding to the first frequency point, and the second preset ephemeris data is set for the type corresponding to the second frequency point, wherein the first preset ephemeris data may include multiple first preset ephemeris parameters, and the number, format and definition of the first preset ephemeris parameters are indicated by the type corresponding to the first frequency point, and the second preset ephemeris data may include multiple second preset ephemeris parameters, and the number, format and definition of the second preset ephemeris parameters are indicated by the type corresponding to the second frequency point; then, the first pre-conversion satellite orbit data can be determined according to the first preset ephemeris data, and the specific calculation process can refer to the existing satellite positioning algorithm, which is not repeated here. Similarly, the second pre-conversion satellite orbit data can be determined according to the second preset ephemeris data; then, the first preset ephemeris data is converted into the type corresponding to the second frequency point and the first post-conversion satellite orbit data is determined, and the second preset ephemeris data is converted into the type corresponding to the first frequency point and the second post-conversion satellite orbit data is determined. The above conversion method can refer to Figure 3 The description of step 302 is not repeated here; finally, the first error is determined according to the first satellite orbit data before conversion and the first satellite orbit data after conversion, and the second error is determined according to the second satellite orbit data before conversion and the second satellite orbit data after conversion. The first satellite orbit data before conversion can be used as a standard reference, and the difference between the first satellite orbit data after conversion and the first satellite orbit data before conversion is positively correlated with the first error. The second satellite orbit data before conversion can be used as a standard reference, and the difference between the second satellite orbit data after conversion and the second satellite orbit data before conversion 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. In this way, the type with a smaller error after conversion can be used as the target type to improve the accuracy of satellite orbit calculation.

[0091] In a possible embodiment, the first error and the second error need to be within an 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 are not determined as target types to prevent the error from being too large after data conversion.

[0092] It can be seen that by determining the target type, a more appropriate target type can be determined and the accuracy of satellite orbit calculation can be improved.

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

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

[0095] Among them, the difference data may include at least one of the number of format differences, the number of difference definitions with derivation relationships, the derivation error coefficient of each difference definition with a derivation relationship, and the number of difference definitions without a derivation relationship. 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 greater the error.

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

[0097] The preset difference condition includes at least one of a number threshold of format differences, a number threshold of difference definitions with derivation relationships, a derivation error coefficient threshold of each difference definition with derivation relationships, and a number threshold of difference definitions without derivation relationships.

[0098] In this way, the 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, convert the first ephemeris data into target ephemeris data to update the current ephemeris data.

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

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

[0102] Among them, different ephemeris data have corresponding parameter fitting algorithms, such as the parameter fitting algorithm corresponding to 16 ephemeris parameters, the parameter fitting algorithm corresponding to 19 ephemeris parameters, etc., which will not be described in detail here.

[0103] Step 408: Determine satellite orbit data according to the parameter fitting algorithm and each target ephemeris parameter.

[0104] It can be seen that through the above data processing method, the storage resource overhead and power consumption overhead can be greatly reduced while ensuring the satellite orbit calculation accuracy without obvious accuracy loss.

[0105] The steps not described in detail above can be found in Figure 3 The description of the steps of the method will not be repeated here.
