Abstract
A system and a method for determining a satellite antenna attitude are disclosed. Radio signals from a satellite, such as a GPS satellite, are received by a plurality of coupled antenna elements forming an antenna array. Local attitude values of the antenna array and/or the antenna elements with respect to a reference plane are determined using a shaft encoder or gyro, whereas a carrier-phase antenna attitude is determined from the received radio signals. The array and/or array elements are rotated over a predetermined angle and a correction value of the antenna attitude is determined from a time-averaged difference between the local attitude values and the carrier-phase attitude values.
