HM400 Modem August 09, 2018 Resource Type Data Sheets Categories: HM Systems HM400 HeloSat Download data sheet 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. Download the Data Sheet to learn more!
