Research on Calibration Method of Beidou RDSS Test System
The Beidou RDSS test system is a closed-loop test system specially used to test the RDSS unit measure-ment of the Beidou user terminal.This paper analyzes the dynamic parameters of the outbound RF signal,the meas-urement characteristics of the inbound analytic parameters and the main parameter calibration methods of the sys-tem,and analyzes and evaluates the uncertainty of the inbound power through calibration tests.The results show that the method can not only provide reference for the formulation of measurement calibration specifications,but al-so lay a foundation for the development of measurement calibration devices.
