Abstract:	This paper presents preliminary implementation results and performance of the GNSS combined receiver unit installed in GNSS Sensor Station. The GNSS combined receiver unit can processing the GPS and Galileo navigation signal such as the GPS L1, L2C, L5 for GPS signals and E1, E5a for Galileo signals within the single box unit for GNSS Sensor Station. To get the fast signal acquisition and tracking performance in condition with weak signal level, it is applied with acquisition scheme with matched filter plus FFT and several tracking loops for integrator, discriminator, and loop filter module. As a receiver unit performance parameters, this paper presents the signal processing channel number for each system, signal sensitivity of signal acquisition and tracking phase, navigation solution, and TTFF(Time To First Fix) for each receiver operation mode.
