RC4600 ACU Board Set
Location Readiness Status
In the lower right corner of the display, a message is displayed showing the status of the location
calculation. Three messages may be displayed:
1) PARAMETER NEEDED. The pointing angle calculation requires 3 sets of data:
a. Antenna lat/lon
b. Antenna Bearing
c. Satellite Information
If lat/lon and/or heading is missing/invalid, the user will need to go to POSITION mode
(2.1.1.2.2.5) to enter valid data. If satellite information is missing/invalid, the user will need to
supply that information via the mechanisms described in section 2.1.1.1.3.
2) AZIM/ELEV RANGE ERROR. These messages will occur if the pointing solution calculation
yields an azimuth angle that is outside the clockwise or counter-clockwise azimuth software limit
or outside the up or down elevation software limits. The appropriate message will be displayed to
indicate that the RC4600 does not think it can move the antenna to the correct position to acquire
the satellite. The user may have to move the antenna to place it in an orientation that will allow
the mount to move to the required position. Note that this message may indicate that the current
position data is incorrect (example: wrong heading).
3) READY TO LOCATE / PRESS <ENTER>. This alternating message indicates that the RC4600
considers the calculated pointing solution valid. Pressing the <Enter> key will initiate automatic
movement to find the selected satellite as described in section 2.1.1.2.2.3.2.
2.1.1.2.2.3.1 Satellite Selection
Several pieces of information must be provided to describe a satellite to the RC4600 before the satellite
may be automatically located:
LONGITUDE: described in decimal degrees (180.0W to 180.0E)
INCLINATION: the number of degrees of orbital inclination. If a satellite is described as having an
inclination greater than zero, the RC4600 will consider it an inclined orbit satellite and subsequently
attempt to track its movement.
BAND: the RF band that the user's equipment will be receiving from the satellite. The band information
helps determine tracking movement size and timing. Throughout the RC4600, the bands are assigned
numbers from the following list: <0-C 1-Ku 2-L 3-X 4-Ka 5-S>
When the <1> key is selected from the main LOCATE screen, the following screen appears to allow the
user to select new satellite information via three methods.
