Problems solved by technology
[0004] However, the satellite discrete-time queue simulation system including ONE is implemented based on a single computer, and the simulation system software cannot be distributed and expanded.
For the simulation of large-scale satellite systems, the number of satellites is large and the processing logic is complex, and the processing method based on a single computer of the ONE emulator cannot adapt
Specifically, when the number of satellites is several hundred, the simulation efficiency of the ONE system is extremely low, and the simulation system will crash due to problems such as operating system process scheduling waiting or deadlock, and the simulation cannot be performed.

Description
technical field [0001] The invention relates to the technical field of simulation, in particular to a satellite system-oriented distributed simulation system and a simulation method thereof. Background technique [0002] With the strong demand of the society for the improvement of satellite information services such as communication, remote sensing, and navigation, the world's major satellite powers have proposed large-scale satellite system construction ideas for different applications. The research and construction of large-scale satellite systems are characterized by great difficulty, high investment, and long period. Therefore, before substantial investment in large-scale satellite systems, it is necessary to use simulation systems to simulate the functions, indicators, and design schemes of the proposed system. Using simulation system to simulate large-scale satellite system has become the basic premise of satellite system construction. [0003] The simulation of the s...
