HM System

Engineered based on software-definable modem (SDM) technology and Hughes enhanced scrambled code multiple access (SCMA) waveform, the HM System brings cost-effective and commercial-off-the-shelf (COTS) communications products and solutions ideal for government applications.

The HM System employs a commercially-based, open standards architecture and frequency band-agnostic platform that enables affordable, resilient solutions to meet a wide variety of mobility and portability requirements for government users. With the first gateway installed in September of 2015, the rapidly growing HM System can now provide global satellite-on-the-move for airborne, maritime and land-mobile platforms and on-the-pause capabilities for users in the field.

Suitable applications for the HM System include intelligence-surveillance-reconnaissance (ISR), border patrol, search and rescue, disaster response, wildfire monitoring, oil platform communications, cellular backhaul and airborne BLOS communications for manned/unmanned, fixed and rotary-wing platforms.

HM 100 HUB Modem

HM100

The HM100 is the gateway modem for the Hughes HM System, an efficient and agile SATCOM system for government applications, whether fixed, mobile, or portable. A commercially based platform for ground station deployment, the HM100 boasts an open standards architecture and is frequency band-agnostic. It enables resilient, affordable networking solutions to meet the wide range of mobility and portability requirements demanded by government users.

The HM100 can be used as a standalone SCPC modem or be integrated into a robust, scalable HM Gateway. In the HM Gateway configuration, it is fully integrated under the HM Network Management System to support larger networks. HM Gateways provide Communications-on-the-Move (COTM) capabilities globally for airborne, maritime, and land-mobile platforms.

Engineered with Hughes Software-Definable Modem (SDM) technology and Scrambled Code Multiple Access (SCMA) waveform, the HM100 brings cost-effective and Commercial-off-the-Shelf (COTS) communications that make it ideal for government applications. The innovative Hughes SCMA waveform enables highly secure, the next-generation performance of mobile video, voice, and data capabilities for SATCOM applications.

The Hughes HM400 is the next-generation software-defined modem for satellite communications (SATCOM) on-the-move. Building off the success of the award-winning HM200, the HM400 leverages the unique Hughes Scrambled Code Multiple Access (SCMA) Waveform technology that enables efficient bandwidth use for smaller antennas. The HM400 can operate over multiple frequencies (L-, Ku-, Ka-, Mil Ka, and X-band) and provides the capability to host a large suite of standardized and commercial waveforms like DVB-S2X. The HM400 also provides the capability to access worldwide SATCOM services through existing VSAT and MobileSat service providers or customer-specific networks/gateways.

The HM400 was designed with flexibility in mind, leveraging an open architecture that enables use with any qualified system components that are best suited for delivering mission-specific requirements. One key enhancement in the HM400 includes increased resiliency to withstand the harsh environmental conditions, such as high altitude flight, lightning strikes, and Electromagnetic Interference (EMI). This makes the unit ideal for applications ranging from disaster response, storm tracking, and military operations to agriculture surveillance and airborne geological surveys. The enhanced resiliency enables reliable Beyond-Line-of-Sight (BLoS) video and data communications, even in harsh environmental conditions.

Benefits: 

  • High throughput data rates for efficient video and sensor data transmissions 
  • Enhanced resiliency with SCMA Waveform 
  • Ruggedized to support high altitude flight applications Lightning/EMC/EMI protection circuitry 
  • Open architecture for use with variety of qualified small antennas 
  • Low Size Weight and Power (SWaP) footprint 
  • Frequency band agnostic 
  • Supports mobility on land, sea or airborne platforms
HM500 ManPack Terminal

The Hughes HM500 ManPack Terminal is a lightweight, multiband man-pack satellite terminal that provides forward deployed teams a highly portable and secure communications solution. At a transport weight of less than 31 pounds, it exemplifies the growing market trend for manpack terminals - reduced Size, Weight and Power (SWaP) requirements.

Designed with advanced commercial satcom technology for defense and public safety missions, the HM500 transportable terminal offers multi-band operation in a very lightweight ruggedized package using pre-configured settings over one of multiple frequencies, including Ku-, Ka-, Mil Ka- and X-band. Its simplified set-up, quick deployment and high data rates brings international users an ideal portable communications solution needed across a wide range of applications, from disaster relief to military operations. The HM500 is available for operation on any of the Hughes system platforms to suit specific requirements, including the innovative software-defined HM System and the industry-leading JUPITER™ System, the first VSAT platform with System on a Chip (SoC) technology incorporating the latest DVB-S2X air interface standard.
