iDirect Government Unveils New Man-Portable SDR Modem for Satellite Communications

iDirect Government (iDirectGov), a provider of satellite communications to the United States military and government, has unveiled its REVOLUTION 450mp (man-portable) software-defined radio (SDR) modem that extends satellite communications orbit and waveform choices for the warfighter regardless of location.

The 450mp is the first 4-Series SDR, introduced with the new Evolution Defense 4.6 software. The Evolution Defense 4.6 platform incorporates improved security, including flexible key exchange for crypto-agility, strengthened transmission security (TRANSEC), and augmented Communication Signal Interference Removal (CSIR) technology.

With the 450mp SDR, the Department of Defense (DOD) has options for satellite orbits and waveforms for its mission-critical operations, including secure satellite communications and intelligence, surveillance, and reconnaissance (ISR).

Featuring a small footprint with an overall 30% reduction in overall size, weight, and power (SWaP), the 450mp SDR supports multiple orbits–geostationaryhighly Elliptical orbitmedium-Earth orbit, and low-Earth orbit and a variety of waveforms all on one modem. The high-performance and secure satellite modem expands resiliency for users at the tactical edge and provides flexibility for ever-evolving missions.

The man-portable modem allows operators to build and run multi-orbital communications networks that can stand up to cyber and electronic warfare threats. The 4-Series SDR modem is designed to meet government standards, namely the Federal Information Processing Standard (FIPS) 140-2 Level 3 and Wideband Global SATCOM.

“The REVOLUTION 450mp SDR focuses on security, resiliency and mobility—the crucial foundations of iDirectGov’s Defense platform,” said Tim Winter, president of iDirect Government. “Additionally, Evolution Defense 4.6 delivers enhanced communications, protection, performance, and efficiency in support of the company’s defense and government customers whenever and wherever they need effective satellite communications. Formidable together, the 450mp and Evolution Defense 4.6 will bring resiliency and flexibility improvements to mission-critical communications at the tactical edge.”

Since its beginnings in 2007, iDirectGov has supported the DOD and other agencies, solving their communications challenges with effective and exceptional delivery.
