VP ONCORE COMMAND REFERENCE
Back to Index
POSITION-HOLD POSITION (@@As)
Note: The input/output messages detailed here are available only if
VP receiver Options ‘A’, ‘B’, or ‘I’ are installed.
The user can specify receiver coordinates for Position-Hold applications
such as timing to increase the timing accuracy, and real-time differential
master station applications. This command is used to enter the position
to be held. Note that this command will only be executed if the Position
Hold Option is currently in the disabled mode. The position to be held is
specified in the same units as the initial position coordinates of latitude,
longitude, and height (to the same resolution). The height parameter can
be either referenced to the GPS reference ellipsoid or Mean Sea Level
(MSL.)
The datum specifying the coordinate system for the fixed position
coordinates must be the same as the coordinate system specified by the
datum currently in use. Note that all three parameters must be specified.
The valid ranges of each parameter are the same as those specified in
the Latitude, Longitude, and Height commands.
Default values: Latitude = 0º (Equator)
Longitude = 0º (Greenwich Meridian)
Height = 0 m (GPS)
