Abstract: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...
Keywords:Pseudo-random code ranging  Chip tracking loop  Processing rate  Clock jitter
