A review of research on GNSS antenna technologies at DRDC Ottawa Research Centre

GPS is currently the main Global Navigation Satellite System. GLONASS, the Russian GNSS, became fully operational few years ago. Other GNSSs will become soon available and a new generation of low cost receivers can take advantage all the systems to improve accuracy or robustness in a challenged environment. Such receivers need performant antennas and RF front-ends. This paper presents a review of research work on GNSS antenna technologies carried out at DRDC Ottawa Research Centre in collaboration with several universities.
