Technical Field

[0001] This invention relates to the field of integrated aerospace information applications, specifically to a method, equipment, medium, and product for planning satellite demand for airborne platforms. Background Technology

[0002] The statements in this section are provided only as background information in relation to this disclosure and may not constitute prior art.

[0003] Currently, there are many types of remote sensing satellites, and the information products they provide vary greatly, differing in terms of Earth coverage, timeframe, quality, content, and timeliness. Ensuring that these numerous remote sensing satellites meet the operational needs of airborne platforms is a key issue that requires resolution.

[0004] Based on a comprehensive analysis of the airborne platform's mission type, mission area, mission time, and flight track data, the required information support content (including information quality, information content, and information latency) for this flight activity is determined. This process optimizes satellite selection, plans the numbering of available satellites and their operational windows, and provides the results of the demand planning. This provides technical support for the efficient support of remote sensing satellite information for various mission activities of the airborne platform. Summary of the Invention

[0005] The purpose of this invention is to address the limitation of remote sensing satellite revisit cycles and the inability of airborne platforms to utilize information provided by remote sensing satellites anytime and anywhere. This invention proposes a method, equipment, medium, and product for planning satellite usage needs of airborne platforms. This enables airborne platforms to efficiently support their flight activities with remote sensing satellite information by customizing the types, numbers, and operating times of remote sensing satellites, under constraints of typical mission time, mission type, and mission area.

[0006] The technical solution of the present invention is as follows: A method for planning satellite usage requirements for an airborne platform includes: Acquire mission parameters and flight trajectory data from the airborne platform; Available satellite constellations are selected from satellite resources based on the mission parameters; Based on the flight trajectory data and the orbital operation data of the available satellite constellation, a first time set is determined for the establishment of a communication link between the available satellite constellation and the airborne platform, and a second time set is determined for the coverage of the target area of ​​interest in the mission parameters by the available satellite constellation. Based on the overlapping periods of the first time set and the second time set, a satellite usage demand planning result containing available time windows is generated.

[0007] Furthermore, the task parameters include task time, task area, task type, and target area of ​​interest; The step of filtering available satellite constellations from satellite resources based on the mission parameters includes: The available satellite constellation is obtained by selecting satellites from the satellite resources that meet the requirements of the mission time, mission area, and mission type.

[0008] Furthermore, before determining the first time set for establishing a communication link between the available satellite constellation and the airborne platform based on the flight track data and the orbital operation data of the available satellite constellation, the method further includes: Load the ephemeris data of the available satellite constellation, and parse it to generate the position data of the satellites in the available satellite constellation at different times; Based on the location data and the target area of ​​interest in the mission parameters, calculate the satellite's elevation angle to the target area of ​​interest; Based on the elevation angle, select high-elevation-angle available satellite constellations from the available satellite constellations; The determination of the first time set for establishing a communication link between the available satellite constellation and the airborne platform specifically includes: determining the first time set for establishing a communication link between the available high-elevation satellite constellation and the airborne platform.

[0009] Further, the step of filtering out high-elevation-angle available satellite constellations from the available satellite constellations based on the elevation angle includes: Calculate the absolute value of the difference between the elevation angle and 90 degrees, and the time interval between adjacent transits of two satellites with different numbers; The high-elevation-angle available satellite constellation is selected from the available satellite constellations according to the order of the absolute value of the difference from smallest to largest and the order of the adjacent transit time interval from smallest to largest.

[0010] Furthermore, the first time set for determining the available satellite constellation and the airborne platform to establish a communication link includes: Obtain the beamwidth range parameters of the receiving antenna of the airborne platform; Based on the flight track data, the orbital operation data of the available satellite constellation, and the beamwidth range parameter, the time periods during which the satellites in the available satellite constellation are within the beamwidth range are calculated to obtain the first time set.

[0011] Further, determining the second time set of the target area of ​​interest in the mission parameters covered by the available satellite constellation includes: Obtain the Earth observation beam angle values ​​of the satellites in the available satellite constellation; Based on the orbital operation data and the Earth observation beam angle value, the time period during which the satellite covers the target area of ​​interest is calculated to obtain the second time set.

[0012] Furthermore, the satellite usage planning results include: satellite name, satellite number, and corresponding available time window; The results of the satellite usage planning are also associated with priority identifiers, which include high priority, medium priority, or low priority.

[0013] The present invention also proposes an electronic device, comprising: At least one processor; and a memory communicatively connected to said at least one processor; The memory stores instructions that can be executed by the at least one processor, and the at least one processor executes the instructions stored in the memory to perform the method described above.

[0016] Compared with existing technologies, the advantages of this invention are: Compared to existing applications of remote sensing satellites supporting airborne platform activities, this invention has the advantage of fully considering the constraints of satellite revisit time on the completion of airborne platform tasks, and proposes a mechanism and method for remote sensing satellites to support airborne platform tasks, thus meeting the high-efficiency requirements of remote sensing satellites for information support to airborne platforms.

[0019] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0020] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0021] Example 1 This embodiment proposes a satellite demand planning method for airborne platforms. It considers the ground mission planning problem that the airborne platform needs to perform before takeoff. If satellite demand planning is not carried out, the airborne platform will likely not have any remote sensing satellite resources available after arriving at the mission area at the mission time. In order for the airborne platform to successfully complete the mission, satellite demand planning needs to be carried out on the ground before the airborne platform takes off. This makes up for the problem that satellites are likely to be unavailable, effectively improves the purpose of airborne platforms using remote sensing satellite information to support flight activities, and enhances the application value of remote sensing satellite information.

[0022] The prerequisite for applying this method is that the airborne platform can load all available remote sensing satellite ephemeris data on the ground before takeoff, and that preliminary mission plans and flight path plans have been generated, such as mission planning packages and trajectory planning packages.

[0023] Please see Figure 1 A method for planning satellite usage requirements for an airborne platform specifically includes the following steps, and the entire process is completed in the ground mission planning subsystem.

[0024] First, the mission planning subsystem receives the mission time, mission area, mission type, and target area parameters from the airborne platform. It then selects available satellite constellations that meet the mission requirements from the available satellite resources. Next, by loading the ephemeris parameters of the available satellite constellations, it parses the orbital parameters of the available satellites and generates satellite position data at different times. By calculating the elevation angle of the selected satellites relative to the target area, it selects combinations of high-elevation satellites. Finally, by calculating the airborne platform's flight track and receiving performance parameters, it calculates the time set for establishing a communication link between the aircraft and the satellites, and outputs the intersection of the time sets, thus realizing the requirement planning capability.

[0025] See Figure 2 Based on data analysis of the target area, the elevation angles of satellites to the target area are calculated. This calculation is then used to further filter available constellation satellite resources. The filtering principle is that the elevation angle value should be as close to 90 degrees as possible, and the time interval between adjacent transits of two high-elevation satellites with different serial numbers should be as small as possible. Typical values ​​are determined according to system requirements. Based on these rules, available satellite constellations are then selected. High-elevation-angle satellite constellations were selected from the data. ,in ; See Figure 3 Based on the flight trajectory parameters of the loaded airborne platform and the beamwidth range parameters of the airborne platform's receiving antenna, the time set for establishing a communication link between the satellite and the airborne platform is calculated. ,in .

[0026] See Figure 4 The satellite's position and latitude / longitude data at different times are generated based on the orbital parameters of the selected high-elevation satellites. In addition, the analysis of satellite Earth observation beam angle values ​​yields a set of time windows for complete satellite coverage of the target area of ​​interest. This process involves iterating through all available satellites (M satellites in total), requiring M calculations to generate the coverage time window sets for satellite 1, satellite 2, and so on up to satellite M. ,in .

[0027] See Figure 5 For each satellite in the available satellite constellation. The intersection of the time window for establishing a communication link between the airborne platform and the satellite and the time window for the satellite to fully cover the target area of ​​interest is calculated to obtain the available time window T3.

[0028] ,in .

[0029] The calculation process involved in a method for planning satellite usage requirements for an airborne platform includes the following steps: The first step is for the mission planning subsystem to receive the mission time, mission area, mission type, and target area parameters from the airborne platform, and then select available satellite constellations that meet the above mission requirements from the available satellite resources. ;

[0030] in These are the parameters for task time, task area, task type, and target area of ​​interest.

[0031] By loading the ephemeris parameters of available satellite constellations, the orbital parameters of the available satellites are parsed to generate satellite position data at different times. , These represent longitude, latitude, altitude, and time, respectively. The second step involves calculating the satellite elevation angles to the target area based on data analysis. This calculation then filters available satellite constellation resources again, prioritizing elevation angles closer to 90 degrees and minimizing the time interval between adjacent transits of two high-elevation satellites with different serial numbers. Based on these rules, available satellite constellations are then selected. Select high-elevation-angle usable satellite constellations: ,in ; The third step involves calculating the time set for establishing a communication link between the satellite and the airborne platform, based on the flight trajectory parameters of the loaded airborne platform and the beamwidth range parameters of the airborne platform's receiving antenna. ,in

[0032] The fourth step involves generating latitude and longitude data of the satellites at different times based on the orbital parameters of the selected available high-elevation satellites. In addition, the analysis of satellite Earth observation beam angle values ​​yields a set of time windows for complete satellite coverage of the target area of ​​interest. This process involves iterating through all available satellites (M satellites in total), requiring M calculations to generate the coverage time window sets for satellite 1, satellite 2, and so on up to satellite M. ,in .

[0033] The fifth step involves analyzing each satellite in the available satellite constellation. The final satellite usage planning result is obtained by intersecting the time windows for establishing communication links between the airborne platform and the satellite, and the time windows for the satellite to fully cover the target area of ​​interest. The available time windows for the selected satellites are then determined. ,in .

[0034] Finally, a satellite usage planning result for an airborne platform is obtained, which includes elements such as satellite name, satellite number, and corresponding available time window. Different priority requirements can be superimposed, such as high priority, medium priority, and low priority.
