Abstract
A customer satellite terminal provides seamless hand-off from a descending satellite to an ascending satellite in an equatorial MEO constellation at RF. The hand-off from the descending satellite to the ascending satellite is conducted when the propagation delay from the ascending satellite and the descending satellite are equal, by aligning first and second amplitudes, first and second frequency offsets, and first and second phases.
