Correction of Ionospheric Delay on GLONASS using the GPS Navigation Message

Naoki Arai, Kazuaki Hoshinoo

Abstract:	The GLObal Navigation Satellite System (GLONASS) navigation message does not include ionospheric parameters. So we can not correct ionospheric delay when we use a GLONASS L1 receiver. This paper shows the correction of the ionospheric delay on GLONASS L1 signal by using ionospheric parameters in the GPS navigation message. We placed 8 channels GLONASS L1 receivers in different places of Japan (Sapporo, Tokorozawa, Fukuoka, and Naha). These receivers include GPS receiving unit. The ionospheric delay at GLONASS frequency was calculated from a delay at GPS frequency. We corrected GLONASS pseudorange by using ionospheric delay at GLONASS frequency. Vertical bias error was decreased a few ten meter using the ionospheric correction.
