Get support for a range of customer applications

Based on the digital video broadcasting — satellite — second generation (DVB-S2) waveform standard DVB-S2, our DVB modems support commercial and military systems, including IPSTAR, WINDS, and TSAT. These custom modems span 4 Mbps to 1500 Mbps user data rates and operate in C-, Ku-, and Ka-bands.

Viasat can meet complex & custom design needs

Our modems incorporate complex (turbo/LDPC-based codes, higher order modulation, and high-speed) digital modems with implementation loss from theory around 0.5 dB. The DVB-S2 modem operates within 0.35 dB of theory with a QPSK rate 1/2 code running at 50 Msym/ sec.

We have also developed several distinct modems or modem subsystems exceeding data rates of 300 Mbps using turbo/LDPC-based FEC, as well as modems optimized for low size, weight, and power (SWaP) applications.

HI-BEAM transceiver

Ruggedized for on-ground/in-air operation

The Viasat highly integrated bandwidth-efficient advanced modulation (HI-BEAM) two-way modem is designed to provide high-speed, standards-based communication in a low SWaP environmentally-sealed package. Rigorously designed to work on ground vehicles, littoral buoys, fixed masts and towers, the HI-BEAM also operates on fixed-wing propeller aircraft and helicopters.

DVB-S2 mini-receiver

Low SWaP, easy transport

The Viasat DVB-S2 Mini-Receiver 5100 is an innovative satellite communications device leveraging the power and bandwidth efficiencies of the DVB-S2 waveform standard.

This DVB-S2 receiver’s low SWaP makes it ideal for transportable and small form factor satellite terminals, enabling deployed warfighters to securely access core Global Information Grid (GIG) services while on the move.
