The Tracking Performance Analysis of Proximity Link Signal Based on CCSDS Protocol

As the current universal proximity link protocol,the CCSDS protocol is widely used in data communication of proximity space. firstly,This paper introduces the signal system of this protocol,and then analyzes the performance of the cur-rent 2 tracking algorithms( PLL and EKF) ,finally implements the MATLAB structure. The simulation results indicate. That Extended Kalman filter( EKF) has better tracking precision and wider dynamic adaption range compared with phase lock loop ( PLL) .
