The military community currently uses the Milstar satellite system for low data rate (i.e. 75 to 2400 bps) two-way communications using the 44 and 20 GHz frequency bands. Development and installation of the Global Broadcast Service (GBS) is currently underway providing high data rate (i.e. up to 23.5 Mbps) broadcast service using the 30/20 GHz frequency bands. Interest has been expressed by the Department of Defense (DoD) in demonstrating an airborne capability that will allow non-simultaneous reception of GBS and Milstar using a single antenna. The Milstar reflector antenna would continue to be used for transmiting to Milstar. Milstar would also be used to demonstrate a GBS reachback channel. A demonstration of this capability that includes a recently developed 20 GHz antenna and radome integrated with a Milstar terminal and GBS receive suite has been completed.
