Satellite locator system
DCFirst Claim
1. A satellite dish apparatus operably connectable to a satellite receiver, the apparatus comprising:
- a satellite dish defining a focal point; and
an automated positioning stem that selectively controls positioning of the satellite dish, the automated positioning including;
a feedhorn and a signal converter operably located at the focal point of the satellite dish;
an azimuth control system and an elevation control system operably coupled to the satellite dish to selectively change an elevational position and an azimuth position of the satellite dish in accordance with a search pattern; and
a search control system operably coupled to the azimuth control system and the elevation control system and to the signal converter such that the search control system continuously averages an output signal reading from the signal converter during movement of the satellite dish in the search pattern to generate a dynamic average signal strength and uses the dynamic average signal strength as a threshold level for discarding any subsequent output signal readings as representing potentially valid satellite signals if the subsequent output signal reading is below the threshold level.

Abstract
A satellite locator system used with a motor home has a parabolic reflector antenna dish, feedhorn and signal converter mounted on a turntable supporting electronic controls and elevation and azimuth motors operable to rotate the turntable and change the elevation of the dish to locate and target a satellite. A plastic dome mounted on a base plate attached to the roof of the motor home encloses the dish, feedhorn, signal converter, turntable, electronic controls, and elevation and azimuth motors. The dome has an inner semi-hemispherical surface located close to the signal converter to improve the signal strength. A remote console wired to the electronic controls is operable to initiate the satellite search and monitor the status of the satellite search.
