POSITION-HOLD POSITION
The user can specify receiver coordinates for timing applications to increase the
timing accuracy. This command is used to enter the position to be held. Note that
this command will only be executed if the Position Control (@@Gd) position hold is
disabled.
The position to be held is specified in the same units and referenced to the same
datum (WGS 84) as the initial position coordinates of latitude, longitude and height
(to the same resolution). The height parameter is referenced to the GPS reference
ellipsoid. Note that all three parameters must be specified. The valid ranges of each
parameter are the same as those specified in the Combined Position Message
(@@Ga).
Default values: Latitude = 0° (Equator)
Longitude = 0° (Grenwich Meridian)
Height = 0 m (GPS Height)
