Abstract: An approach for determining remote terminal antenna alignment in a satellite communications system is provided. A point in time for an expected conjunction of an a remote terminal antenna, a satellite in communication with the remote terminal and the Sun is determined based on predetermined positional data. An interference level imposed by the Sun on communication signals between the antenna and the satellite is measured at a number of respective points in time. A one of the points in time is determined when the interference is at a peak level. Then information regarding alignment of the antenna with respect to the satellite is determined, wherein the determination of the antenna alignment information is based on a comparison between the one point in time of the peak interference level and the expected point in time of the conjunction of the antenna, the satellite and the Sun.
