Airborne BLoS SATCOM

Resource Type
Data Sheets

The Hughes Airborne Satellite Communications (SATCOM) System is an integrated solution providing a constant and reliable en route and outroute transmission of critical real-time information to support any airborne mission.

ISR Data Transfer

Ideal for Beyond-Line-of-Sight (BLoS) en route connectivity requirements, the innovative Hughes HM400 modem paired with an advanced airborne antenna that will provide high throughput communications over satellite. The HM400 can transmit HD video and other critical sensor information from of the aircraft for ISR missions and real-time situational awareness on the ground. It also has the capability of transmitting voice or command and control data to the aircraft for manned or unmanned operations.

En Route Communications

The multifunctional Hughes Airborne Microsat Modem (AMM) is focused on providing en route communications and a variety of military and commercial aircraft to include Very Important Person Special Air Mission (VIPSAM) platforms for senior leaders in the US Government. The platform features MF-TDM which facilitates the greatest overall modem efficiency and provides up to 30 Mbps for en route communications on the aircraft. This modem is built for transmitting voice and data for those on these aircraft in need of broadband on-the-go.

Open Architecture

Designed with an open architecture, the Hughes modems are Commercial-Off-The-Shelf (COTS) products that can be readily installed into a wide range of manned or unmanned, fixed, or rotary winged platforms, and can be interfaced with a variety of antenna solutions also with an open architecture. User flexibility is vital in today’s evolving technological environment, enabling the Hughes Airborne SATCOM System to be optimized for any mission. Based on a unique Software-Defined Modem (SDM) and employing the specialized Hughes Scrambled Multiple Access (SCMA) waveform, they deliver a superior level of mobile video, voice, and data capabilities for all airborne BLoS systems. Ground stations utilize the Hughes HM300 modem, which is designed with the same SDM and interfaced to a customized ground antenna. Packaged in a standard 1U rack-mountable enclosure, it can be readily installed in customers’ teleports and mobile ground stations anywhere in the world. Hughes has integrated its airborne system in a variety of platforms; utilizing different antenna options. The system’s architecture is based on customer-specified requirements with the desire to meet certain Size, Weight, and Power (SWaP), or performance characteristics.
