Multichannel Dual Frequency GLONASS Software Receiver

S. Abbasian Nik, M.G. Petovello

Abstract:	Global Navigation Satellite System (GNSS) technology is rapidly evolving. With the recent revitalization of the Russian GLONASS system, with a current constellation of 16 satellites and the promise of 24 satellites by 2010 (Revnivykh 2007), it is worthwhile to concentrate on GLONASS as a method of GPS augmentation to achieve more reliable and accurate navigation solutions. This paper presents a software receiver that can acquire and track both L1 and L2 GLONASS civil signals for an unlimited number of GLONASS satellites. The paper presents the key differences between the GPS and GLONASS signals and highlights the corresponding software receiver changes needed to accommodate these differences. Acquisition, tracking and navigation data demodulation and extraction are discussed. Results show that the receiver is able to successfully track the L1 and L2 civil signals and that the corresponding navigation solutions are commensurate with those of a commercial GLONASS-enabled receiver.
