Deploy Software-defined, Mission-aligned SATCOM Service

Connect to your warfighters anytime and anywhere with multi-orbit HM System satellite ground technology that’s flexible, scalable and secure.


For the modern warfighter, connectivity is more than a communications line. It’s a lifeline when the certainty of secure communications means everything. It’s also why we invented the Scramble Code Multiple Access (SCMA) waveform to protect SATCOM transmissions in every theater – on a helicopter, aboard an RPA, on the water and on the ground. 

Built into our HM System, the SCMA waveform sets apart our software-defined satellite ground capability for military applications. It’s enabled industry firsts, like through-the-rotor, multi-megabit data transmission; multi-orbit SATCOM to and from RPAs; and on-demand, satellite-enabled cellular connectivity for emergency comms.

Flexible and cost-effective, the commercially based HM System meets mission requirements for Department of Defense (DoD) customers with features such as:

  • Open standards architecture
  • Multiple frequency bands (L-, Ku-, Ka-, Mil Ka, and X-band) and orbits (GEO, NGSO)
  • Portable modems with low Size Weight and Power (SWaP)
  • Ruggedized equipment able to withstand high altitudes, lightning strikes and Electromagnetic Interference (EMI)

Manufactured in the Hughes factory in Maryland, U.S.A., HM System equipment includes:

  • HM400 Modem designed for SATCOM on-the-move with flexibility and resiliency in mind. Ideal for a range of applications, including disaster response, storm tracking, military operations, as well as agriculture surveillance and airborne geological surveys.
  • HM100 Hub available for use as a standalone SCPC modem or integrated into a robust, scalable HM Gateway for Communications-on-the-Move capabilities.
