Embodiment Construction
[0028] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but this does not constitute a limitation of the present invention.
[0029] Such as Figure 1 to Figure 6 As shown, the unambiguous reference waveform receiving method applied to the BPSK signal of the present embodiment includes the following steps:
[0030] Step S1: Phase rotate and split the received satellite navigation signal to obtain two orthogonal signals respectively z i ( t )and z q ( t );
[0031] Step S2: The local pseudocode generator generates a local replica signal according to the pseudocode phase information obtained by the pseudocode phase detector X ( t ), X ( t ) respectively with z i ( t )and z q ( t ) correlation, accumulation, get I P and Q P , the calculation formula is
[0032]
[0033]
[0034] The value of T is generally selected as 1ms;
[0035] The local reference waveform generation modu...
