Experimental validation of a reconfigurable GLONASS sub-sampling receiver

Résumé

Positioning and navigation with Global Navigation Satellite System (GNSS) like GPS, GLONASS, BEIDOU and GALILEO are more and more deployed in various telemetry applications. Achieving reliable and accurate results in the main objective especially while dealing with safety and critical applications, which need to be robust under challenging environments. Thus, the key solution for a better accuracy position is to integrate a new structure based on Radio Frequency sub-sampling (RFS) aiming to reduce the complexity by including only one RF front-end capable to collect multiple signals at the same time. This RFS architecture allows to digitize the received signals as close to the antenna as possible and has been found to be a useful tool in system design and prototyping. This paper presents an experimental assesment of the reconfigurable GNSS receiver based on GLONASS signals to demonstrate its operation and functionality. To carry out the measures, real-world satellite data are needed. A measurement companion on the GNSS receiver was conducted based on GLONASS sigals in the G1 band which were generated by the Labsat2 equipment. To look for the visible satellites, the Parallel Code-Phase Search Acquisition algorithm was used (PCS). Acquisition results for GLONASS G1 are shown and the performance of the receiver is discussed
