碩士 === 清雲科技大學 === 電機工程所 === 100 === The purpose of this research is to develop and apply the Recurrent S_CMAC_GBF (RSCMAC) to enhance the accuracy of GPS (Global Positioning System). The performance is implemented and tested by a FPGA chip. This research presents to Recurrent S_CMAC_GBF improve the dynamic error of the GPS, and feedback to the receiver to do error correction, by improving the satellite receiver positioning accuracy. We used a low cost commercial module (Trimble Lassen IQ) receiver and the expensive commercial module (Trimble 5700) receiver to improvement the GPS dynamic error, so that low-cost commercial modules (Trimble Lassen IQ) receiver positioning accuracy improve to further. Finally, the FPGA chip is used implement Recurrent S_CMAC_GBF hardware structure, the result will be back to computer by RS-232 to verify.
