specific Embodiment approach 1
[0052] The specific embodiment one, is used for the satellite coverage in the multi-layer satellite network environment and the inter-satellite link analysis method, it is realized by the following steps:
[0053] Step 1. Initialization: Obtain the design requirements and design parameters of the multi-layer satellite network.
[0054] Step 2. Create a space running scenario. If this scene is created for the first time, then perform step 21. If the space scene already exists in the constellation database, then perform step 22;
[0055] Step 21: Create a new scene, set the start running time, end running time and current time node of the scene, and execute step 3;
[0056] Step 22: Import the scene from the constellation library, dynamically adjust the actual running time of the scene, end the running time and the current time node, and execute step 51;
[0057] Step 3. Build a distributed constellation. If the satellite to be built exists in the satellite database, perform st...

A satellite coverage and inter-satellite link analysis method used in a multilayer satellite network environment relates to the field of mobile satellite communication, and aims to solve the problems that the satellite cannot achieve global coverage of the ground surface and establish a permanent inter-satellite link in part of a multilayer satellite network. The satellite coverage and inter-satellite link analysis method comprises the steps of: acquiring design parameters of the multilayer satellite network, establishing a spatial scene, setting a scene operation cycle, reconstructing or introducing satellites and a ground station according to orbit parameters, and establishing a multilayer satellite network model at an initial stage; analyzing continuous access time of the satellite to the ground station according to relative positions of satellite orbits and the ground station; carrying out hierarchical processing on an asterism, setting parameters such as a satellite elevation angle, and analyzing coverage features of the satellites to the ground surface; establishing inter-satellite links for the satellites in the same layer and the interlayer satellites, and analyzing and counting continued period of the interlinks; and constructing a data transmission framework, and transmits the coverage features and link features of constellation to a demand side.
Description
technical field [0001] The invention relates to the field of mobile satellite communication, in particular to a satellite coverage analysis and link analysis technology. Background technique [0002] First of all, it is of great significance to build an integrated air-space-ground information network. In the 21st century, space is an important scientific and technological resource as well as an important strategic resource, and the space-space-ground integrated network is not only a bridge for human beings to enter space, but also a means and basis for human beings to understand and use space. The air-space-ground integrated information network will change the status quo of frequently switching protocols in space-ground operations, improve the efficiency of interoperability, change the situation of too many space-ground-specific protocols, promote standardized development, change the situation that information cannot be shared well, and give full play to the application bene...
