Subject: Data lost for GRAS station.

Dear colleagues,

Very bad data are being received from GRAS station since doy 100 around 23:40 GMT.
The last file delivered to IGS and EUREF was the x file for doy 100.
Up to now, the following files are invalid : only L1 frequency data are available (L1, C1, D1)
We suspect frequency jamming with L2 frequency in the area of Grasse due to unknown and not scheduled tests.
We are investigating.

With best regards,
