The GR-310 is a rugged fully featured tactical Satcom radio solution delivering reliable field deployable communications with unparalleled value. ■[Wideband frequency band operation]-The GR-310 supports in wideband frequency band from 30MHz to 512MHz, so it is possible to use in land force, navy and air force in manpack/mobile conditions. ■[Lightweight and Compact Design]-Using the latest lightweight alloys the GR-310 weight 4kg(4.9kg with 11Ah/12V, Lithium Ion battery pack). Its small physical size makes it comfortable to wear and operate when deployed as a tactical manpack. Designed for the harshest field environments, the GR-310 complies with MIL-STD-810G and is fully immersible to a depth of one meter ■[Advanced calling feature]-The GR-310 radio supports advanced selective calling, banish calling, Automatic mode exchange, 5 digit SMS, Beacon, GPS tracking which are included as standard ■[Remote control]-The GR-310 radio has full operation access to the radio with remote control. ■[Enhanced DSP noise reduction]-MELP1000 vocoder system provides outstanding voice quality by reducing radio frequency interference (RFI), and the effects of electrical interference by enhancing audio signals to provide easier listing. The level of noise reduction can be easily selected to suit prevailing conditions. ■[Automatic antenna tuner]-Whips and untuned wire antennas are simply deployed using the inbuilt, fully automatic antenna tuner. For temporary fixed station and tunable tactical antennas are available. ■[Intuitive operation]-Glocom’s well known intuitive operator interface ensures that operating the GR-310 very simple. Principal key functions are performed using a keyboard array mounted on the front panel. The operator is guided by 128x32 LCD graphics display. The display has adjustable backlighting, allowing

maintenance of night vision or high levels of luminescence in poor visibility. Network station addresses and radio numbers are stored in easily accessible address books and as little as two key strokes will initiate a call. ■[Extended operation time]-The low current consumption of the GR-310 radio enables it to operate for over 20 hours on one battery pack. Spare quick change battery packs are small and lightweight. The battery packs contains the charger management system and can be charged when connected to the radio or separately with charger including grid charger, solar charger. ■[SATCOM function]- The GR-310 supports military tactical Satcom functionality, so it makes possible to communicate in beyond horizon condition. It is possible to communicate in worldwide in anytime, anywhere. ■[Digital Encryption and scrambling]-The GR-310 can be fitted with a variety of scrambling and digital encryption functions for voice and data security. The GR-310 includes secure calling(an innovative narrow band voice scrambler providing secure point to point or point to multipoint communication), AES 256 bit digital encryption assuring secure voice and data operation ■[Frequency Hopping]-The unique, easy to use frequency hopping function requires no central synchronization station, has short entry or late entry time delay and requires no hopping handshakes. Hopping rate of 10 hops per second, using 25 digit hopping encryption key, and user selectable hopping bandwidth to suit the antenna type in use, the system provides excellent protection against Electronic Warfare (EW) attacks.
