Dear colleagues,

We checked that the data of GMAS station was abnormal in the following period.
Causes were the abnormalities of the satellite tracking equipment which supplies the standards signal to GMAS GPS receiver. We will
carry out the tune up of GPS receiver's clock offset in 11/14(Doy318).

Doy317
00:00:00-05:59:30 Normal data; clock offset 9.359usec
06:00:00-08:59:30 No data
09:00:00-09:05:30 Normal data; clock offset 55.51usec
09:06:59-09:08:29 No data or abnormal data
09:09:00-23:59:30 Normal data; clock offset 576.46usec
