GPS／BD2／GALILEo反射信号接收机兼容分析与设计实现
Design and Implementation of GPS/BD2/GALILEO Multi-Navigation System based on Compatibility Analysis
摘要
Abstract
The key technologies of multisystem integrated GNSSR receiver is dis cussed. The method of multisystem GNSSR receivers is introduced, based on the platform of FPGA and DSP. Kinds of technologies, such as data extraction and interpolation, stored C/A code, the phase of CA code and the Doppler of carrier with FFT are searched, and seg ment correlation and FFT to acquire a serial crosscorrelation power of reflected signal and local CA code is used, etc. which the multisystem compatibility problem in sampling,acqui sition,tracking,processing and so on are solved,and a verification system to implement this system is constructed.关键词
