Description

technical field [0001] The invention relates to the field of satellite orbit simulation, in particular to a satellite orbit simulation method and device. Background technique [0002] With the increasing application of satellites, in various engineering applications, in order to grasp the operation status of satellites in real time, it is necessary to perform simulation calculations on satellite orbits. For example, when studying the area coverage performance of small Earth observation satellites, it is necessary to simulate the satellite orbit calculation process to verify whether the designed satellite orbit meets the area coverage requirements; another example is when studying spaceborne sensor systems such as synthetic aperture When using the Synthetic Aperture Radar (SAR) simulation system, since the satellite is flying in a specific orbit, it is also necessary to model and simulate the satellite orbit in order to provide carrier operation excitation data for the spaceb...

Problems solved by technology

[0004] The STK toolkit can meet people's requirements for orbit simulation calculation of a single satellite and relative orbit calculation between multiple satellites to a certain extent. However, the toolkit is closed (the source code is not open), and it is not convenient to embed the orbit control algorithm program. , and the single-satellite orbit simulation toolkit can only perform single-satellite orbit simulation, and the multi-satellite orbit simulation toolkit can only perform multi-satellite orbit simulation. For different simulation applications, different simulation programs need to be established to complete
