Abstract
In an embodiment, an apparatus includes an antenna assembly, a modem, and a beam steering controller. A beam steering controller is configured to determine a beam pointing direction of the antenna assembly to be able to one or both of switch a first communication link with a first satellite to a second communication link with a second satellite or establish and maintain the first communication link with the first satellite. At a start of a determination of the beam pointing direction, one or more of an orientation of the antenna assembly is unknown, positions of a plurality of satellites are unknown, or downlink frequencies of the plurality of satellites are unknown.
Claims19
A device comprising:
- an antenna assembly configured to transmit and receive beams with a first satellite;
- a modem electrically coupled to the antenna assembly;
- and
- a beam steering controller electrically coupled to each of the antenna assembly and the modem, the beam steering controller configured to determine a beam pointing direction of the antenna assembly to be able to one or both of switch a first communication link with the first satellite to a second communication link with a second satellite or establish and maintain the first communication link with the first satellite,
- wherein at a start of a determination of the beam pointing direction, one or more of an orientation of the antenna assembly is unknown, positions of a plurality of satellites are unknown, or downlink frequencies of the plurality of satellites are unknown, and
- wherein the beam steering controller is configured to find any satellite of the plurality of satellites that is assigned to downlink to a cell associated with the device to yield a found satellite, wherein the found satellite comprises the first satellite, and wherein the beam steering controller is configured to establish the first communication link with the first satellite.
