Home > GRX-8000
The GRX-8000 is Elbit Systemsâ fifth generation of advanced ECCM NATO Band IV and NATO Band III+, Dual Mode – fixed frequency (FF) and frequency hopping (FH) line-of-sight broadband radio system. With advanced jamming-resistant electronic counter-countermeasures (ECCM) the multi-interface GRX-8000 software-defined radio relay system enables secure, interference-free PtP, PtMP and IP tactical communications.
The GRX-8000 Multi Channel Radio (MCR) system provides high capacity, robust wireless connectivity and high link availability between general HQs and field command posts, in field and in maritime deployed CPs, EW or surveillance platforms to regional centers for video/high definition data links. The battle-proven system is designed to support latest IP and legacy communication protocols.

- Remote control facility (SNMP)
High-Capacity robust tactical communications
The GRX-8000 provides enhanced performance with multi-mode, high speed data transmission, providing aggregated data transmission capacity up to 200 Mbps. Featuring an extremely high system gain, the dual mode system supports long distances over 100Km at Line-of-Sight conditions.
Advanced ECCM for jamming immunity
The GRX-8000 performs synchronous and adaptive fast frequency hopping for simultaneous, interference-free communications. Embedded reliable Forward Error Correction (FEC) and adaptive coding and modulation (ACM) provide jamming immunity. Various encoding, jammed packets retransmission and advanced iterative decoding in conjunction with interleaving techniques eliminate the effects of high-power and long-time pulse jammers, as well as heavily jammed environments.
Advanced TRANSEC cryptographic techniques
AES256 bit encryption/decryption for data and System Control (SysCon).
Frequency Hopping
The GRX-8000 is capable of Synchronous Full Band Fast Frequency Hopping (FH) with Hybrid ARQ protocol covering the total 600 MHz frequency range in NATO Band IV.
Point-to-multi-point configurationÂ
Up to 6 points in fixed frequency (FF) and frequency hopping (FH) modes. The RF output in trunk node may be transmitted through a sectorial antenna or can be split to several directional antennas (with each antenna pointed to a different access point).
Automatic and fast link tuning and establishment
Implemented using Elbit Systems’ two axes electro-mechanical antenna rotator controlled by the GRX-8000.
Multi-interface
The GRX-8000 supports a wide variety of services ranging from traditional telephony to broadband multimedia for the very latest C4I applications. The GRX-8000 includes a wide range of interfaces including Ethernet LAN / IP 1000Base-T, G.703 E1 (2Mbps).
