Abstract :
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 37 ns to 7 ns and restrict the broadcast error within plusmn 20 ns
