Embodiment Construction
[0028] The carrier phase cycle slip suppression method based on the phase error clipping processing provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] figure 1 It is a flow chart of the carrier phase cycle slip suppression method based on phase error clipping processing provided by the present invention.
[0030] Step 1: Build a Carrier Tracking Loop
[0031] The carrier tracking loop is composed of four parts: a carrier phase discriminator, a phase error limiter, a loop filter and a voltage controlled oscillator, and the phase error limiter includes an instantaneous phase error limiter and a phase error cumulative value The limiter has two parts. The input end of the phase detector is the signal input end of the carrier tracking loop, the output end of the phase detector is connected to the instantaneous phase error limiter, the output end of the instantaneous phase error limiter is connected to the ph...
