Low rate fiducial data in BINEX 7f format. These files are
derived from the one second fiducial data (fidGps) files by a process
of smoothing the one second data and then interpolating them instead of simple
decimation which leads to noisier data. Each time a
fifteen minute batch of fidGps data are received, low rate data are
extrated from it and written to the f30Gps file.
GPS/MET data are stored in the so-called 30/1 second format with
one second data and 30 second data stored separately. In this case,
the one second data go directly to the fidGps file
and the 30 second data go to this file.
