Notes

2017-01-25T17:45Z 1933/3 025 - 2017-03-26T11:45Z 1942/0 085
After the downgrade to firmware 5.15 the setting to log GLONASS L2 P-code data was not eanbled and therefore no GLONASS L2 P-code data was logged for WSRA during this period. Logging L2 P-code for GLONASS was enabled again on 26 March 2017.
2017-01-25T16:45Z 1933/3 025 - 2017-01-25T17:45Z 1933/3 025
The receiver f/w was upgraded to version 5.20 but thereafter restored again to 5.15 due to errors in the newly introduced RINEX3 long names. During the downgrade all receiver setting have been lost, which were restored by hand over a period of about one hour. At 18:45 operation was again nominal.
2015-02-10T15:00Z 1831/2 041 - 2015-07-13T19:39Z 1853/1 194
The receiver was connected during this period to the external H-MASER, the 10 MHz from the MASER was detected but not enabled in the receiver settings. On June 13 2015, around 19:39, the external frequency was enabled and clock steering by the receiver was disabled. At this time the receiver clock error became 0.24126 ms.
2015-02-10T15:00Z 1831/2 041 -
All systems (GPS+GLO+GAL+BEI+QZSS+SBAS) are tracked and data is archived in daily 30 sec interval, hourly 10 sec interval and 15 minute high-rate 1 Hz multi GNSS RINEX version 3 files, as well as the raw data in T02 format. The GPS and GLONASS data is kept also as daily 30 second and hourly 10 second RINEX version 2 files for legacy purposes.
1999-09-01T05:50Z 1025/3 244 - 2000-04-27T23:59Z 1059/4 118
Shared receiver with WSRT, data is not independent. Rawdata files for WSRA (CBI format) were created from WSRT rawdata files (conan binary format), and then converted into RINEX.
2000-04-28T00:00Z 1059/5 119 - 2000-06-05T15:50Z 1065/1 157
A bug in the data logging software resulted in double difference ambiguities that are not integer. Hence, ambibuity fixed solutions are not correct during this period, although the ambiguity float solutions are okay. 1059/5/00:00 (28/4) - 1065/1/15:50 (5/6).
1998-03-17T15:09Z 0949/2 076 - 2005-10-13T06:00Z 1344/4 286
There has been a small inconsistency in the antenna height of WSRA with respect to WSRT, which uses the same antenna. In the rinex file it was during this period given as 0.3935 instead of 0.3888, as is for WSRT. A difference of 4.7 mm. The reason for this difference was because of consistency with the value used by AGRS.NL. For our own processing we have always been using the correct antenna height of 0.3888 for both WSRT and WSRA.
2014-06-20T12:00Z 1797/5 171 - 2015-01-26T15:00Z 1829/1 026
Due to a faulty hub no hourly 10 second data was sent to the LDC and this data is not available. Only daily files, with 30 second data, are available.

Data gap because of receiver breakdown. On 2005-04-12 the receiver was replaced by an identical type (S/N 251) courtesy Royal Observatory of Belgium.
2010-07-18T13:02Z 1593/0 199 - 2010-07-22T11:36Z 1593/4 203
Data gap because of receiver breakdown. On 2010-07-22 the receiver was replaced by an identical type (S/N 229) and firmware version.
