Army interested in iPad-sized satellite terminals

By: Nathan Strout

The Army is interested in a new commercial satellite service with a focus on small, mobile terminals.

According to a July 2 request for information, the Army wants to expand beyond line-of-sight communications capabilities for tactical users with a new commercial satellite service. The proposed network would put small terminals, slightly bigger than the larger iPad Pro, in the hands of soldiers in the field, allowing them to communicate via a low earth orbit or medium earth orbit constellation.

John Swart, the director of the Army's Technology Applications Office, said that the Army was simply interested in learning more from industry. He declined to provide further comment.

The Army currently relies on a combination of military and commercial satellites for beyond line-of-sight communications, but satellite coverage and the size of terminals can limit their availability. The suggested satellite service would provide the Army with global coverage, excluding the polar regions.

Part of the benefit of using LEO or even MEO satellites is that they reduce the need for larger, bulkier terminals. Since they are closer to Earth, users need less powerful terminals to communicate with the satellites. That means the terminals can be physically smaller, and that's a key focus of the request.

The Army wants the commercial satellite service provider to supply troops with so-called “ultra sat terminals” ― basically small terminals 12 inches by 12 inches. Ideally, the Army wants terminals for aircraft, vehicles and dismounts that are small enough to fit in a rucksack, although airborne terminals can be larger. These terminals would preferably be able to switch between satellites as they move from coverage area to coverage area, allowing for uninterrupted service.

Broadly, Department of Defense leaders have said that as they develop new satellite architectures they will have face a significant expense in replacing legacy terminals that are not compatible with modern satellites.

While the service said it is willing to obtain the satellite services and terminals from different suppliers, they would prefer to go with one provider. It's not clear from the request how many terminals the Army would be interested in acquiring.

Responses to the request were due July 31.

  • Lockheed Martin-Built AEHF-5 Protected Communications Satellite Now in Transfer Orbit

    Lockheed Martin-Built AEHF-5 Protected Communications Satellite Now in Transfer Orbit

    The Lockheed Martin (NYSE:LMT)-built AEHF-5 satellite is now responding to the squadron's commands as planned. The squadron began "flying" the satellite shortly after it separated from its United Launch Alliance Atlas V 551 rocket approximately 5 hours and 40 minutes after the rocket's successful 6:13 a.m. ET liftoff. AEHF-5 complete a geostationary ring of five satellites delivering global coverage for survivable, highly secure and protected communications for strategic command and tactical warfighters operating on ground, sea and air platforms. Besides U.S. forces, AEHF also serves international partners including Canada, the Netherlands and the United Kingdom. "This fifth satellite adds an additional layer of flexibility for critical strategic and tactical protected communications serving the warfighter. This added resilience to the existing constellation will help ensure warfighters can connect globally to communicate and transmit data at all times," said Mike Cacheiro, vice president for Protected Communications at Lockheed Martin Space. "In the weeks ahead, AEHF-5 will move towards its operational orbit, deploy all of its solar arrays and antennas, and turn on its powerful communications payload for a rigorous testing phase prior to hand over to the Air Force." AEHF-5, with its advanced Extended Data Rate (XDR) waveform technology, adds to the constellation's high-bandwidth network. One AEHF satellite provides greater total capacity than the entire legacy five-satellite Milstar communications constellation. "Individual data rates increase five-fold compared to Milstar, permitting transmission of tactical military communications, such as real-time video, battlefield maps and targeting data," said Cacheiro. "AEHF affords national leaders anti-jam, always-on connectivity during all levels of conflict and enables both strategic and tactical users to communicate globally across a high-speed network that delivers protected communications in any environment." Lockheed Martin designed, processed and manufactured all five on-orbit AEHF satellites at its advanced satellite manufacturing facility in Sunnyvale, California. The next AEHF satellite, AEHF-6, is currently in full production in Silicon Valley and is expected to launch in 2020. The AEHF team includes the U.S. Air Force Military Satellite Communications Systems Directorate at the Space and Missile Systems Center, Los Angeles Air Force Base, Calif. Lockheed Martin Space, Sunnyvale, Calif., is the AEHF prime contractor, space and ground segments provider as well as system integrator, with Northrop Grumman Aerospace Systems, Redondo Beach, Calif., as the payload provider.
