| Abstract: | This paper reviews the Global Position System (GPS) satellite signal first,and then introduced the Software Define Radio (SDR) into Global Navigation Satellite System (GNSS) re- ceiver.It also presents the development of a new kind of GNSS receiver,which is upgradable,highly flexible and multi-system compatible.In order to apply it on the Micro-Satellite Platform (MSP), the hardware system was made up of Field Programmable Gate Array (FPGA) and Digital Signal Processor (DSP).The software structure is also p... |
