[IGSSTATION-8247] GRAC00FRA: data resubmitted

[Romain Fages]

Author: R. Fages

Dear colleagues,
Due to storage cleaning misconfiguration, the data from 173j until today 
were very incomplete, with some hourly files containing only one epoch.
The receiver regularly stopped tracking but the the daily and hourly 
data have been recreated with all possible epochs.
Daily rinex 3 files have been resubmitted for the last 6 days and hourly 
rinex 3 for the last 2 days.

Sorry for inconveniences.
