- Abstract
- The Key technologies of GNSS Receiver for GNSS Sensor Station is under development as a part of GNSS ground Station. A wide-band antenna and RF/IF components and SW Signal Processing Unit to cover the GPS and Galileo signals for GNSS receiver had developed and its performance was verified by using GPS live signal and GNSS RF signal simulator from Spirent TM . Also, we gathered GIOVE-A Signal by using H/W Antenna and RF/IF units in IF-level as sampling frequency and bit number, 112MHz and 8bits, respectively by using the developed wide-band antenna and RF/IF components. Data acquisition was done by using commercial data acquisition device from National Instrument TM . The gathered data was fed into SW receiver to process Galileo E1 to verify Galileo signal processing by Galileo live signal from GIOVE-A. In this paper, the wide-band antenna and RF/IF components and SW Signal Processing Unit to cover the GPS and Galileo signals for GNSS receiver for GNSS sensor station is presented. Also, developing FPGA based signal processing unit and its verification is presented.
