Research on Calculation Design of Navigation Chip for Precise Point Positioning
The Beidou Navigation Satellite System (BDS) provides the precise point positioning (PPP) service in China and surrounding areas, with broadcasting PPP correction data through B2b signal of BDS. By receiving signals and demodulating correction message, user receivers can carry out real-time precise point positioning calculation, and obtain high-precision position information. This paper introduces the PPP model and parameter estimation. The calculation of the navigation chip is designed for PPP, with applying two independent CPU cores. The application of the chip in agricultural machinery is indicated in this paper.
