Abstract
Facing the increasingly complex electromagnetic environment, it is an attempt to introduce DS/FH hybrid spread spectrum technology to the field of TT&C. For DS/FH receiver, despreading and dehopping proceed respectively. However if DS/FH navigation signal is dealt with in the same way, there is no difference between DS/FH navigation signal and the existing DS signal. The code tracking algorithm proposed in this paper makes full use of frequency hopping information so that the correlation peak becomes very sharp. Computer simulation shows that the code tracking accuracy of DS/FH navigation signal reaches at 0.0028 m (CNR = 40 dB Hz) and the maximum of the multipath error envelope is 0.062 m (MDR = −10 dB), far better than the performance of existing navigation signals.
