9. Report of WG GNSS and Discussion
Survey results on the present situation of the Remote Calibration Services
Sub-WG surveyed and 14 NMIs replied.
9 NMIs providing remote calibration services. 3 NMIs have plan to provide them in future.
Service categories of the remote calibration: - Frequency : 9 NMIs - Time : 1 NMI - Time scale difference : 2 NMIs
5 NMIs already have the quality system for the remote calibration service.

10. Action plan for Remote Calibration Services
Report of WG GNSS and Discussion
Action plan for Remote Calibration Services
Discuss and create a guideline of the remote calibration service in T&F field.
Discuss and create a guideline of the use of GPS(GNSS)-DO in the traceability system.
9 NMIs want to participate in the sub-WG : NICT, KRISS, TL, NIM, NIMT, A*STAR, NPLI, SIRIM, and NMIA 
Coordinator of this sub-WG under WG GNSS
: Dr. M. Imae (NMIJ/AIST)
