Abstract: In one embodiment of the present disclosure, a device for detecting a zone of communication between a user terminal and a satellite constellation including a plurality of satellites in non-geosynchronous (non-GEO) orbit includes one or more processors and memory. The memory stores instructions that, as a result of being executed by the one or more processors, cause the device to: determine a location of the device, wherein the location corresponds to a field of regard for detecting the zone of communication, and wherein the field of regard corresponds to an antenna aperture of the phased array antenna; evaluate a level of communication between the phased array antenna and the satellite constellation associated with the field of regard; and output, to a user of the device, an indication of the level of communication between the phased array antenna and the satellite constellation associated with the field of regard.

Abstract: In one embodiment of the present disclosure, a method is provided for configuring an endpoint terminal for communication with a plurality of satellites in non-geosynchronous orbit. The endpoint terminal has an antenna system defining a limited field of regard for satellite communication. The antenna system is capable of gimbaling in order to move the field of regard. The method includes orienting the field of regard in a first position to communicate with a first satellite traveling in a first orbital plane; gimbaling the antenna system to move the field of regard from the first position to a second position to communicate with a second satellite traveling in a second orbital plane; establishing communication with the second satellite; and as the second satellite travels in the second orbital plane, gimbaling the antenna system to move the field of regard from the second position to a third position.
