Design of BD/GPS data analysis system based on FPGA

For Unmanned Aerial Vehicle (UAV) satellite navigation and positioning system of data acquisition. This paper designs a data analysis plan for BD/GPS navigation system using FPAG as the platform. The design includes a serial receiving module and a data analysis module. The data format is based on the standard NMEA-0183 protocol. The data analysis module judges the data cycle and uses a comma count value to obtain the required navigation information and performs navigation information Code conversion until the completion of the analysis of BD/GPS data. Finally, the simulation test shows that this design of the data analysis module can be well extracted BD/GPS satellite data in the corresponding location information.
