The data from GNSS station ILDX (17, France) are available since session 2019-176a. Missing data are definitely lost.

ILDX breakdown since session 152t. Inbestigation aborted on day 158 due to a storm at Aix. No idea of what is causing the disfunctioning. Station dowmn will hopefully be fixed next week day 163. GNSS Antenna is still in place and no power failure has been reported by local contacts. E.Poirier

We do not know the cause of the problem.

We apologize for the inconvenience.
