Motorola GPS Products M12 Oncore User’s Guide Supplement Revision 1.0 01/25/00 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) 24
