Embodiment Construction
[0040] Below in conjunction with accompanying drawing, working principle and working process of the present invention are further explained and illustrated:
[0041] Such as figure 1 Shown, a kind of satellite navigation signal channel SCB characteristic detection method comprises steps as follows:
[0042] (1) Gather satellite navigation signals;
[0043] Navigation signal acquisition or data reading. A clock with good short-term stability is used locally to generate a sampling clock, and satellite navigation signals are continuously collected under this clock, and sent to subsequent units for real-time continuous processing or post-processing after storage.
[0044] (2) Carrier stripping is carried out to the satellite navigation signal collected in step (1), obtains baseband signal;
[0045] Use open-loop or closed-loop tracking methods to estimate carrier frequency and phase, and perform carrier stripping to obtain baseband signals.
[0046] (3) carry out low-pass filt...
