Abstract
In order to effectively solve the influence of satellite navigation signal generation equipment on the fixed ambiguity, the Beidou high-precision signal radio frequency direct generation technology is studied, which can effectively separate the initial phase of the carrier phase and the hardware delay in the channel, and reduce the carrier phase fractional deviation caused by the spaceborne device to reduce the ambiguity. The influence of the fixed degree can effectively solve the consistency of the pseudo code and the carrier, so that the phase of the carrier and the pseudo code is fixed, and the phase relationship will not change with the passage of time, so as to realize the consistency of the navigation signal and ensure the generation of the signal carrier. The stability of the initial phase of the phase reduces the influence on the estimation of the fractional fluctuation of the carrier phase, thereby improving positioning accuracy.
