[0036] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. Unless there is a conflict, the embodiments in this application and the features in the embodiments can be combined with each other in any way. In addition, although a logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0037] The terms "first" and "second" in the specification and claims of this application and the accompanying drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "comprising" and "including" and any variations thereof are intended to cover non-exclusive protection. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to the process, method, product, or device.

[0038] Given this current situation, the inventors of this application, after creative reflection and analysis, concluded that existing constellation simulation visualization solutions primarily offer solutions at the system architecture level. Specifically, current visualization technology solutions for large-scale low-orbit satellite constellations are primarily based on container cloud solutions. This technology addresses the problems inherent in traditional computing using multiple physical computers, such as poor scalability, fault tolerance, and maintainability, as well as the inability to compute large-scale constellation data. It also improves the efficiency of large-scale data computation compared to traditional computing methods.

[0039] However, this technical solution still fails to address the low computational efficiency, poor data transmission and update timeliness, and low rendering efficiency caused by the large amount of computational data required for large-scale constellation orbital data. Specifically, for example: 1) When users select a long-term experience in large-scale constellation visualization, the amount of orbital data required for computation is enormous, reducing system computational efficiency; 2) The client-side rendering of large amounts of orbital data places enormous pressure on the visualization system, resulting in low rendering efficiency and even system crashes; 3) When orbital data is updated in the system, the visualization system will be in a waiting state, causing constellation satellite animation to lag.

[0040] To further address at least one of the technical issues identified above, in one possible implementation, the present application provides a constellation orbit data processing method that calculates satellite orbit data by time slice, effectively improving computational efficiency. In one embodiment, this method can be implemented as a constellation satellite orbit data calculation program, or it can be flexibly deployed as an operating carrier based on actual computing resource conditions. The visualization system serves as the data receiver and is used to graphically display satellite orbit data. The constellation orbit data processing method specifically includes the following steps:

[0041] S101. Determine the required satellite orbit data time slice size according to constellation parameters and constellation size.

[0042] Specifically, the design of a time-sliced ​​satellite orbit data calculation strategy aims to improve program data calculation efficiency by directly reducing the amount of satellite orbit data calculation. Specifically, the satellite orbit period is calculated based on constellation parameters, and the time slice size for each satellite's orbit data calculation is determined based on the constellation size. The constellation satellite operating period is calculated using the following formula:

[0043]

[0044] Where T is the satellite orbit period, a is the orbit radius (Earth radius + orbit altitude), π is the pi constant, and µ is the Earth constant (standard gravity parameter).

[0045] After the satellite orbit period is calculated based on the constellation parameters, the satellite orbit data time slice size t can be determined based on the constellation size to be displayed in the visualization system. In the embodiment of the present application, t=x T, where x is an influencing factor constant determined by the system deployment configuration and the size of the constellation, which can be obtained through experiments. In a preferred embodiment, the time slice size can be initially set to 1-3 times the satellite orbit period.

[0046] The time slice size t of each satellite's orbital data will be determined according to the size of the constellation to be displayed in the visualization system.

[0047] S102: Slice all satellites within the constellation operation time period according to the time slice size, and set an overlapping time period between two adjacent time slices.

[0048] In this step, the constellation operation time period required by the visualization system must be determined. The length of this time period can be adjusted based on actual needs. This constellation operation time period is then sliced ​​based on the time slice size calculated in S100. Slicing involves dividing the constellation operation time period into multiple time slices, with overlapping time periods between adjacent time slices.

[0049] In this embodiment, it is necessary to segment the constellation operation time period of each satellite. Specifically, when the system is initialized, the constellation satellite orbit data calculation program calculates the distance from each satellite to the preset center point of the visual map based on the current time point of the system. , and get its maximum value , then the distance coefficient of each satellite can be obtained based on the ratio of the two. Then the start time of the first time slice of each satellite can be calculated based on the distance coefficient and the satellite orbit period. The formula for the start time of the first time slice of each satellite is as follows:

[0050]

[0051] in, is the starting time of the first time slice of the i-th satellite, Initialize timestamp for the system, is the distance from the i-th satellite to the preset center point of the visualization map, The distance from the farthest satellite to the center of the preset visual map. is the satellite orbit period.

[0052] Finally, the constellation operation time period is segmented according to the start time of the first time slice of each satellite and the time slice size, and the segmentation processing results of all satellites are obtained. It should be noted that since the start time of the calculated first time slice may be before the constellation operation time period, the length of the first time slice in the constellation operation time period may be less than the pre-calculated time slice size. Figure 2 shown.

[0053] Furthermore, for each satellite, the constellation satellite orbit data calculation program will slice the constellation operation time period required by the visualization system into time slices t0, t1, t2, etc. according to the time slice size t. Two adjacent time slices will ensure a certain coverage time period tx0, tx1, tx2, etc., as shown in the following example: Figure 3 shown.

[0054] In this embodiment, data preloading can be achieved by designing the coverage time period to ensure smooth display of the front-end visualization system. At the same time, with the different sharding processing of each satellite, the satellite data can be calculated in a staggered manner. Please refer to the subsequent description of S103 for details.

[0055] It should be noted that, in this embodiment, the length of the coverage period should be less than half of the time slice size. The specific length can be adjusted as needed.

[0056] S103: Receive the time point information provided by the visualization system in real time, and control the calculation and transmission of the orbit data of each satellite corresponding to the time slice according to the relationship between the current time point information and the coverage time period.

[0057] In order to further solve at least one of the technical problems found above, in one embodiment of the present application, the visualization system and the constellation satellite orbit data calculation program directly establish a websocket long connection to communicate data. The satellite orbit data adopts a packet transmission strategy instead of full data loading. Specifically, after calculating the orbit data within a time slice, the satellite number and the orbit data of the corresponding satellite are packaged and transmitted to the visualization system. After the visualization system obtains the data packet, it can analyze and render the satellite orbit data of a single satellite in a single time slice, such as Figure 4 The figure below shows a visualization of orbital data for a time slice. For large-scale constellation satellite orbit data calculation scenarios, this batch-wise data transmission and loading method can greatly reduce the data loading and parsing pressure on the visualization system and improve rendering efficiency.

[0058] After calculating the time slice orbit data, it is necessary to cache the calculated orbit data and mark the time slice as calculated. This mark can be used to avoid repeated calculations when time rollbacks or jumps occur. By using time slicing to calculate satellite orbit data, the calculation efficiency of large-scale constellation orbit data can be effectively improved.

[0059] It should be noted that since adjacent time slices have overlapping coverage time periods, for the time slice to be calculated currently, if the data of the coverage time period of the previous time slice has been calculated in the previous time slice, then the data of the coverage time period will use the calculation result of the previous time slice, and no repeated calculation will be performed. Only the data after the coverage time period needs to be calculated.

[0060] In order to further solve at least one of the technical problems found above, in a possible implementation, the present application also provides a constellation orbit data processing method to establish a satellite orbit data update mechanism.

[0061] Specifically, satellite orbit data updates rely on time information and constellation operation time slices provided by a time synchronization mechanism established between the visualization system and the constellation satellite orbit data calculation program. The constellation satellite orbit data calculation program establishes a time synchronization mechanism with the visualization system, receiving the time information provided by the visualization system in real time and controlling the calculation and transmission of orbit data based on this time information.

[0062] Among them, the specific process of establishing the time synchronization mechanism includes: establishing a long websocket connection between the constellation satellite orbit data calculation program and the visualization system for data communication. When normal time moves forward, the visualization system will synchronize time with the constellation satellite orbit data calculation program every second; when the system user performs time setting, rollback and other time jump operations, the visualization system will immediately synchronize the current time with the constellation satellite orbit data calculation program.

[0063] Please refer to Figure 5 After receiving the time point information provided by the visualization system and completing the synchronization of the time point information, the constellation satellite orbit data calculation program first needs to determine whether the time point information is continuous with the previous time point. If it is not continuous, it means that the user has performed a time jump operation such as time setting or rollback, or an initialization operation. At this time, it is necessary to calculate the orbit data of all satellites in the time slice corresponding to the discontinuous time point information and transmit the calculation results to the visualization system for rendering. During this process, it should be noted that when calculating the orbit data, since this operation may be a rollback operation, it means that the orbit data of the previous time slice may have been calculated and can be read directly.

[0064] This embodiment provides a specific method for calculating the time slice orbital data, that is, first determine whether the time slice is marked as calculated. If it is marked as calculated, directly transmit the cached orbital data of the time slice to the visualization system; if it is not marked as calculated, calculate the orbital data of the time slice and then transmit the calculation result to the visualization system.

[0065] If continuous time point information is received, as time progresses, the constellation satellite orbit data calculation program needs to continuously determine whether the current time point information is within the coverage period of a certain satellite time slice, and then calculate the orbit data of the corresponding satellite in the corresponding time slice. The specific process is as follows:

[0066] First, the current time point information is matched with the coverage time period of all satellites. If the current time information is within the coverage time period of a certain satellite, the satellite is used as the satellite to be updated;

[0067] Then, determine whether the next time slice in the coverage period of the satellite to be updated is marked as calculated. If so, directly transmit the cached corresponding orbital data to the visualization system. If not, calculate the orbital data of the time slice and then transmit it to the visualization system.

[0068] Since the position of each satellite's fragments and coverage time period are not exactly the same during the fragmentation processing, the above-mentioned orbital data calculation method can be used to control the calculation of satellite orbital data at different time points. For large-scale orbital satellite data, this mechanism of loading small amounts of satellite orbital data in batches will greatly reduce the data loading and parsing pressure of the front-end visualization system and improve rendering efficiency.

[0069] To more clearly illustrate the orbit data update mechanism in this embodiment, take three satellites as an example and combine Figure 6 Provide specific instructions.

[0070] Assume that the time point information when the visualization system is synchronized to the constellation satellite orbit data calculation program is T0, and assume that T0 is not continuous with the previous time point information. At this time, it is necessary to calculate the orbit data of the corresponding time slices of all satellites, that is, the orbit data of time slice t1 of satellite 1, satellite 2, and satellite 3 all need to be calculated. If the time slice t1 of a certain satellite is marked as calculated, it can be read directly.

[0071] As time progresses, the system receives continuous time point information. After time T0, the current time point will first fall within the coverage period of satellite 3. At this point, orbital data for time slice t2, one slot after satellite 3's coverage period, will be calculated. Similarly, if this time slice is marked as calculated, it can be directly read; otherwise, it must be directly calculated. Further down the line, at time T1, the orbital data for time slice t2 of satellite 2, then time slice t2 of satellite 1, and finally time slice t3 of satellite 3 will be calculated. This orbital data calculation method only calculates orbital data for all satellites' corresponding time slices when receiving discontinuous time point information. When receiving continuous time point information, the satellite to be calculated is determined based on the location of the coverage period. This method staggers the calculation and update of satellite orbit data, reducing the data loading and parsing pressure on the front-end visualization system.

[0072] It should be noted that Figure 6 Only the scenario with three satellites having different sharding is shown. The orbital data calculation time of each satellite in the continuous time is different. In actual applications, there will be a large number of satellites, and some satellites may have the same sharding. In this case, satellites with the same sharding method will calculate and update the orbital data at the same time, while other sharding methods will calculate and update the orbital data at different times, realizing batch processing of large-scale scenarios.

[0073] In addition, the embodiment of the present application establishes a heartbeat mechanism to synchronize time changes through a websocket long connection, provides an orbit data update mechanism for each satellite, and can solve the problem of animation freeze during data update.

[0074] Please refer to Figure 7 The embodiment of the present application also provides a constellation orbit data processing device 200, which mainly includes a time slice determination module 201, a slicing module 202, a calculation module 203, a transmission module 204 and a time point information synchronization module 205.

[0075] Specifically, the time slice determination module 201 is mainly used to determine the required satellite orbit data time slice size according to the constellation parameters. In the embodiment of the present application, the time slice determination module 201 also includes a time slice determination submodule, which calculates the satellite orbit period according to the constellation parameters and determines the satellite orbit data time slice size in combination with the constellation size. Specifically, the satellite orbit data time slice size t=x T, where x is an influencing factor constant determined by the system deployment configuration and the size of the constellation, which can be obtained through experiments. In a preferred embodiment, the time slice size can be initially set to 1-3 times the satellite orbit period.

[0076] The slicing module 202 is primarily used to slice all satellites within the constellation operation time period according to the time slice size, with an overlap period set between adjacent time slices. This slicing process primarily calculates the start time of each satellite's first time slice during system initialization and slices the constellation operation time period based on the start time of the first time slice and the time slice size. The overlap period should be less than half the time slice size.

[0077] When receiving discrete time points, calculation module 203 calculates the orbital data for all satellites in the time slice corresponding to the discrete time points. As time progresses, it identifies satellites whose information at the current time point falls within the covered time period as pending satellites, and calculates the orbital data for the time slice following the covered time period for all pending satellites. Using time slicing to calculate satellite orbital data effectively improves the computational efficiency of large-scale constellation orbit data.

[0078] The transmission module 204 is used to transmit the calculated satellite orbit data in the time slice to the visualization system for analysis, rendering and display. After the orbit data in a time slice is calculated, the satellite number and the corresponding satellite orbit data are packaged and transmitted to the visualization system. After the visualization system obtains the data packet, it can analyze and render the satellite orbit data of a single satellite in a single time slice, such as Figure 4The figure below shows a visualization of orbital data for a time slice. For large-scale constellation satellite orbit data calculation scenarios, this batch-wise data transmission and loading method can greatly reduce the data loading and parsing pressure on the visualization system and improve rendering efficiency.

[0079] In one embodiment, the slicing module also includes: a slicing processing submodule, which uses the ratio of the distance from each satellite to the preset center point of the visual map to the distance from the farthest satellite to the preset center point of the visual map as the distance coefficient of the corresponding satellite; determines the start time of the first time slice of each satellite according to the system initialization timestamp, each satellite distance coefficient and the orbital period; and slices the constellation operation time period according to the start time of the first time slice of each satellite and the time slice size.

[0080] In one embodiment, the calculation module further includes: after calculating the orbital data for a time slice, caching the calculated orbital data and marking the time slice as calculated. When calculating the orbital data for the time slice, it is determined whether the time slice is marked as calculated. If it is marked as calculated, the cached orbital data for the time slice is directly obtained; if it is not marked as calculated, the orbital data for the time slice is calculated.

[0081] Please refer to Figure 8 According to an embodiment of the present application, an electronic device 300 includes: a memory 301 and a processor 302, wherein the memory 301 stores a computer program corresponding to the aforementioned constellation orbit data processing method that can be loaded and executed by the processor 302. It should be noted that the electronic device also has a display screen for displaying a UI (User Interface). The UI may include graphics, text, icons, videos, and any combination thereof. When the display screen is a touch screen, the display screen also has the ability to collect touch signals on the surface or above the surface of the display screen. The touch signal can be input to the processor as a control signal for processing. At this time, the display screen can also be used to provide virtual buttons and / or virtual keyboards, also known as soft buttons and / or soft keyboards. In some embodiments, the display screen can be one, the front panel of the electronic device; in other embodiments, the display screen can be at least two, respectively provided on different surfaces of the electronic device or in a folding design; in still other embodiments, the display screen can be a flexible display screen, provided on a curved surface or a folding surface of the electronic device. Even the display screen can be set to a non-rectangular irregular shape, that is, a special-shaped screen. The display screen can be made of materials such as LCD (Liquid Crystal Display) and OLED (Organic Light-Emitting Diode).
