Study on Broadcast Control Model of Beidou/Changhe Integrated Navigation System

摘要

This paper compares several models of broadcast time error control through researching on the principle of long-range radio navigation. This model controls broadcast signals through the methods of Kalman filters and adaptive filters separately. Experimental results show that the adaptive filter can reduce the standard deviation of the time error in broadcast signal from 37ns to 7ns and restrict the broadcast error within ± 20ns.
