display will only affect the distance and
bearing figures in the TMS display. The

3.10 Reference stations
The reference station information is assembled in the ST_COORD_DEF.TXT and the
ST_COORD.TXT files. ST_COORD_DEF.TXT is the default file, and it is write protected.
ST_COORD.TXT is updated during operation.
The following information is displayed in the ST_COORD_DEF.TXT and the
ST_COORD.TXT files:
SCID: Super compressed identification number. For messages on RTCM format,
the ID "9999" is displayed. For messages on super compressed format
(SCF), any other number is displayed.
Station ID: The reference station's identification number. This number is not unique for
a reference station.
Station Name: The name of the reference station. If the reference station does not exists in
ST_COORD_DEF.TXT, "???" will be displayed.
Link No.: This number identifies on which link the reference station data are received.
Note Together, the Station ID and the Link number is a unique number. Different
stations can have equal Station ID, but will never be received on the same link.
X, Y, Z: The reference station position in Cartesian ECEF co-ordinate system and
WGS-84 datum.
Update Count: This column shows how many times data have been received from the
reference station. The number is updated every time new position information
or SCF mapping information from the reference station is received.
Note Edit the ST_COORD.TXT file only, not the ST_COORD_DEF.TXT file.
