摘要
Abstract
A real-time GPS receiver prototype is proposed and realized. Solution in this paper provides several feasible and suitable methods in the implementation of real-time GPS receiver, including the code phase estimation method for eliminaling the asynchrony between the acquisition results and the tracking data, along with the satellite/channel allocation algorithm in which the priority calculation is based on both the integrity of the ephemeris and the correlation peak of the signals. Floating point calculation by fixed-point DSP is also optimized. Lastly, a friendly interface is provided, for updating algorithms and support software, making our prototype an ideal platform for algorithms development, verification and evaluation of embedded GPS receivers.关键词
