ViaSat and STM Group successfully demonstrated waveform interoperability between the STM SatLink 2000 modem and the ViaSat Joint Internet Protocol Modem (JIPM) for the U.S. Department of Defense, the companies announced April 27.
    ViaSat said the demonstration milestone establishes the JIPM as the government-standard IP network satellite modem for connecting U.S. forces. The JIPM standard is based on the adaptive and variable coding modulation techniques used in the global DVB-S2 and DVB-RCS standards.
    "The JIPM modem combines the flexibility of the commercial standards with information assurance to deliver secure, high-speed IP communication to military and government agencies. Powered by an IP networking backbone across the service area, warfighters using JIPM-compatible satellite modems can efficiently share voice, video and data communications over military and commercial satellites, including X- and Ka-band," ViaSat and STM said in a joint statement.
    The JIPM program, initiated by the U.S. Defense Information Systems Agency (DISA) aims to provide more options and lower costs to Pentagon and NATO forces through interoperability between modems from different manufacturers.
