Abstract

In order to match the flexible requirements of GNSS receiver design, the solution of developing such a universal platform has grown in importance. In this light, this paper introduces a work for the realization of an experimental FPGA&DSP-based GNSS receiver platform, which is according to the Software Defined Radio (SDR) philosophy. Starting from the justification for the hardware devices selected, this paper firstly describes the whole structure. Then the design of base band channel based on FPGA is presented. This includes the design of an individual base band channel and the design of local code generation. The realization of signal acquisition and tracking in DSP is introduced. Finally a signal tracking experiment is introduced, which justified the platform's availability.
