iDirect Government releases 450 rackmount software-defined modem for enhanced satellite communications

iDirect Government (iDirectGov) has announced the release of the 450 Rackmount (RM) software-defined modem (SDM) that delivers resilient and secure connectivity across theatres, airspace and all mission phases.

The 450RM operates on iDirectGov’s Evolution Defense, Viasat GX, SES Flex and DVB-S2X networks, as well as the military-standard 188/165B Enhanced Bandwidth Efficient Modem (EBEM). It supports operations across geostationary (GEO), highly elliptical (HEO), medium Earth orbit (MEO), and low Earth orbit (LEO) constellations, while maintaining the highest security standards.

Designed for space-constricted environments, the half-rack unit allows two 450RMs to be mounted side-by-side in the rack, minimizing rack space requirements while providing a protected, durable form factor.

“The 450RM is resilient, secure and flexible to suit our troops’ satellite communications at the tactical edge,” said Tim Winter, iDirectGov president. “Its multi-technology architecture delivers optimized performance and efficient operations.”

The 450RM is powered by the 4‑Series SDM architecture, which integrates iDirectGov’s Communication Signal Interference Removal™ (CSIR™) technology and a Federal Information Processing Standards (FIPS)-140-3 Level 3 approved Advanced Encryption Standard (AES) Cryptographic engine for secure, resilient communications. This architecture enables a TRANSEC‑compliant network design that exceeds U.S. government standards and delivers high‑quality voice, video and data across contested environments.
