Subject: IGEX-station DLFT: equipment change 

In view of some problems at the IGEX observation station DLFT, (Delft
University of Technology, the Netherlands), the ASHTECH GG24-receiver used
at the station
has been replaced with another receiver of the same make and type.

The change can be summarized as
*    data collected until JDAY 285 (12/10/1998)
        with ASHTECH GG24 receiver with serial no.120,
*    no data collected on JDAY 286 (13/10/1998) and JDAY 287 (14/10/1998),
*    data collected since JDAY 288 (15/10/1998)
        with ASHTECH GG24 receiver with serial no.163.

The problems with the receiver concerned the logging of raw data messages,
and resulted in complete epochs of data missing from the RINEX observations
files. The number of missing epochs was however relatively small, usually
only a few epochs per day, and the data of the other epochs are not though
to be
affected by this or any other problem.
