Effect of Processing Rate on Regenerative Clock Jitter Performance in Pseudo-Random Code Ranging

The tracking performance of chip tracking loop is an important determinant of ranging accuracy in micro-satellite pseudo-random code regenerative ranging,and digital processing rate has an effect on regenerative clock jitter performance. The different factors effecting on clock jitter are analyzed and tested. The results show that at low ranging signal to noise ratio,the clock jitter depends mainly on the loop bandwidth and the chip rate. While at high ranging signal to noise ratio,the clock jitter is restr...
