3.2.2.7 Position

The POSITION mode allows the user to set the latitude, longitude and heading of the vehicle for
subsequent use in calculating pointing angles to satellites. The first screen that appears shows the
current mount position used in the RC4000. Note: Mount “position” consists of the mounts latitude,
longitude and true heading of the azimuth centerline.

The mount’s position will not be retained at power off unless the position is explicitly saved by pressing
the “4” key. If the position is saved, the date and time that the position was saved is noted.

3.2.2.7.1 LAT/LON

When the user chooses to modify latitude and longitude, a screen appears showing the current lat/lon
and the source of that value. In the example screen the source shows that the current lat/lon was
obtained from the GPS. If the current values had been entered manually “MANUAL” would show for the
source. If the current values had come from the preset vehicle location list (see Preset Locations
configuration 3.3.1.15), the name (ex. WICHITA) of the preset location would appear. If there is currently
no valid lat/lon “NO POS SOURCE” would be displayed.
