Abstract:
A satellite communication system provides for handovers between satellites and multiple gateways. Terminals communicate with a first gateway via a first satellite as beams of the first satellite traverse the region. A second gateway is in communication with the first satellite and hands over to a second satellite. The first gateway is at a first location. The second gateway is at a second location separated from the first location in the orbital direction. Terminals handover to the second satellite as beams of the second satellite begin to traverse the region, and the terminals start connecting to and communicating with the second gateway via the second satellite. After all of the terminals of the plurality of terminals handover to the second satellite, the first gateway hands over to the second satellite and then the terminals in the region communicate with the first gateway via the second satellite.
