Determination of antenna direction using TV signal-strength data
Abstract
A unique method of determining a satellite's antenna direction error, which includes the effects of sensor-error, reflector thermal distortion, etc., was developed. The principle of the method is to apply a nonlinear least squares method to variations in signal strength received simultaneously at various ground stations to obtain the movement of a premeasured antenna gain pattern. Applying this method to the Japanese medium-scale broadcast satellite for experimental purposes, the system's capability and usefulness were confirmed.
