Developed in conjunction with leading satellite hardware and airtime providers, GRM (GRC Rugged Modem) have been tested into iDirect hubs across multiple satellite service provider networks. Supporting both fixed location and mobile applications, they have been extensively trialled on a diverse range of terminals from comms-on-the-move (COTM), to man portable and large static dishes.
Compatible with Evolution and iDirect Velocity networks, IP67 rated and CE Marked, GRM modems are 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.
