Research on Improving the accuracy of testing results for aerospace relay systems using particle swarm optimization algorithm

Many characteristics of satellite communication forwarding are difficult for other communication methods to match. Because satellite signals can cover a very wide area on Earth, they can serve as a hub for communication networks and connect many users who are geographically distant. After the satellite is launched at a designated location, it is necessary to test the performance of the in orbit satellite communication payload. The input-output characteristics are an important technical indicator of the repeater. This article proposes an improved method for testing the input-output characteristics of transponders using particle swarm optimization, and provides a detailed introduction to the testing principle of this method. This method reduces error factors, improves testing accuracy, and enhances testing efficiency.
