L1C/B support of Multi-GNSS Integrated Real time and Archived Information system (MIRAI)

Jun.25,2025
National Space Policy Secretariat, Cabinet Office

We are pleased to announce that the real-time/archived data of QZSS monitoring stations which are available on Multi-GNSS Integrated Real time and Archived Information system (MIRAI) will support L1C/B data as follows in preparation for the service-in of the QZS-6. For other monitoring stations, the timing of support is being considered depending on the L1C/B support status of each station.

- Real-time data: L1C/B data will be supported after the release of the L1C/B-compatible RTCM format. Until then, L1C/B data will not be supported.

- Archived data: Both data in RINEX 4.02 format supporting L1C/B and RINEX 3.04 format not supporting L1C/B will be available from the beginning of July.
