Abstract

A satellite communications terminal for a ship may include an antenna with three antenna feeds operable at respective different frequencies, and communications circuitry coupled to the three antenna feeds and being configurable for a selected antenna feed. The terminal also includes a positioner to mount the antenna to the ship and point the antenna. A controller may select an antenna feed, configure the communications circuitry, and operate the positioner to point the antenna to a selected satellite all based upon the location of the ship and at least one selection rule. The selection rule may be a communications circuitry configuration rule and/or a service level agreement rule.
