GRM 950

rugged satellite modem

GRM 950

GRM 950 is a low-cost, rugged, outdoor iDirect 950mp satellite modem for use in challenging environments.

Developed in conjunction with leading satellite hardware and airtime providers, GRM 950 (GRC Rugged Modem) has been tested into iDirect hubs across multiple satellite service provider networks. Supporting both fixed location and mobile applications, it’s been extensively trialled on a diverse range of terminals from satcom on-the-move (SOTM), to man portable and 1.3m static dishes.

Compatible with Evolution and iDirect Velocity networks, IP67 rated and CE Marked, GRM 950 is designed to meet defence and commercial requirements, while still delivering a cost-effective modem, that’s flexible enough to operate on a diverse range of terminals and networks, yet intuitive enough for end users with minimal training.
