- Abstract
- The GPS L5 signal added newly in the GPS modernization plan was designed to improve the accuracy and availability for civilian users. In order to apply the structural property of this signal, new receiver architectures are needed. In Korea, ETRI is developing technologies of GNSS ground infrastructure and next generation search and rescue beacon from 2007 up to 2010. We are going to develop hardware board per signal frequency for the development of the high performance GNSS receiver which monitors not only GPS but also Galileo system. The combined GNSS receiver is consisted of H/W Antenna, RF/IF units and Signal Processing Unit. The receiver can process wide-bandwidth multiple frequency for GPS L1/L2C/L5 and Galileo E1/E5a signal. In this paper, we are focusing to design and performance of the GPS L5 signal processing board. The hardware board receives IF signal of RF/IF Frontend and process IF signal in the ADC, FPGA, and DSP for baseband process. And the performance of GPS L5 signal processing is verified by compare accuracy, sensitivity with ETRI specification for the Spirent simulator.
