A study on the conceptual design of hybrid sensor station for GNSS

This paper presents the conceptual design results of GNSS sensor station at top level. ETRI involved in developing technologies of GNSS ground infrastructure from 2007 up to 2010. The major target of this project is to develop high performance GNSS receiver for GNSS sensor station. The function of the GNSS receiver unit is to receive the navigation signals from GPS and Galileo satellite and extract the pseudo range, carrier to noise ration, Doppler shift and carrier phase. In this paper, conceptual design results of GNSS receiver which includes the functional block diagram, design parameters, interface among functional block, are presented. Also the design results of major parameters for receiver unit are presented in this paper.
