Abstract
A system for accurate automatic satellite acquisition by a portable satellite terminal. The system includes a software program that coordinates inputs from several measurement aids to control antenna position. These aids include a GPS receiver, antenna azimuth, elevation and polarization angle sensors, and the terminal's modem, DVB receiver and spectrum analyzer, which contains a beacon detector also serving as Receive Signal Strength Indicator (RSSI). For satellite recognition, the spectral analysis and RSSI function are complemented by the lock/unlock indications provided by the modem and the DVB receiver. Under the control of the software program, the modem, DVB receiver and spectrum analyzer, in conjunction with an extensive database of satellites and their signal characteristics, provide the means for reliable validation of final alignment.
