In Orbit Testing Accuracy Analysis of Communication Satellite Transponders

After the launch and orbit determination of high orbit satellites, in orbit testing of satellite transponders will be carried out. In the past testing process, after the completion of the test, it was only possible to simply compare the test results to see if they met the technical requirements. The accuracy of in orbit testing directly affects the accuracy of satellite payload related indicators testing results. By analyzing the error components of various tests during the in orbit testing process, obtained the testing accuracy of typical test items during in orbit testing. Further optimization can be carried out for specific error components, further improve the accuracy of in orbit testing of satellite repeater related indicators.
