VSAT MODE OPERATION
After powering up the RC4000, the MENU screen will appear.
1-LOCATE SATELLITE MENU
2-STOW ANTENNA
CST
<1-2>SELECT <MODE>MANUAL 14:37:23
In VSAT mode, the MENU screen only gives the operator two automatic functions that may be performed.
LOCATE
Selecting <1> will put the RC4000 into LOCATE mode.
If the antenna system has an antenna mounted compass, the following screen will prompt the operator to
confirm that the antenna’s platform is in a safe location (not in a garage, not under power lines, etc.) for
deployment of the antenna.
* ANTENNA MOVEMENT REQUIRED TO LOCATE *
* CONFIRM PLATFORM IN SAFE POSITION *
<ENTER>BEGIN MOVEMENT <MODE>EXIT
After initiating antenna movement, the antenna will be deployed and the LOCATE mode entered.
POS: 39
01N 9449W 180.1 LOCATE
SAT:GALAXY 7 91.0W AZ:-31.1
EL: 40.0
READY TO LOCATE
PRESS <ENTER>
In VSAT mode, the LOCATE screen does not allow the operator to select a satellite. The selected
satellite (and polarization) will be the last one chosen prior to entering VSAT mode.
When LOCATE is first entered, the mount’s position will be automatically initialized with data from the
GPS receiver and the Fluxgate compass. There may be a delay of several minutes while the GPS
receiver generates a navigation solution. After the GPS generates lat/lon, the local magnetic variation is
calculated and applied to the magnetic heading from the compass to form and estimate of the true
heading of the mount.
The latitude, longitude and true heading will be displayed in the POS: field. The pointing solution will be
displayed in AZ: and EL: and the messages “READY TO LOCATE” and “PRESS ENTER” will be flashed.
When ENTER is selected (or the antenna deployment has previously been confirmed), the RC4000 will
automatically begin positioning the antenna to locate the satellite. The previously selected polarization
orientation (Horizontal or Vertical) will be automatically calculated.
The autopeak function will be performed according to how it was configured (signal source, lock
condition, scan range, etc.) prior to entering VSAT mode. Descriptions of the various operations in the
LOCATE sequence will be displayed as the operation progresses.
