The GLObal NAvigation Satellite System (GLONASS) navigation message does not include ionospheric parameters. So we can not correct ionospheric delay when we use a L1-GLONASS receiver. This paper shows the correction of the ionospheric delay on L1-GLONASS signal by using ionospheric parameters in the GPS navigation message. We placed L1-GLONASS receivers of 8 channels 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. GLONASS vertical bias error was decreased to a few meters from a few ten meters by using the ionospheric delay correction.
