Brief Introduction

GNSS Anti-Jamming Receiver AJ7E mitigates jamming by creating nulls in the antenna gain pattern in the direction of Jammers, providing significant anti-jamming protection even in dynamic multi-Jammer scenarios. jamming mitigation is achieved by applying proprietary digital nulls forming algorithms to the signals, creating dynamic nulls to give protection against narrowband and broadband jamming sources.

It has high accuracy in a compact package, it’s designed to meet the mission needs of missile and munitions applications. It provides you with a highly accurate, reliable system in a compact, cost-effective package. The AJ7E Anti-Jamming Antenna delivers accurate GNSS navigation either as a stand-alone system or when integrated with an existing INS Reference System.

Features:

-- Affordable protection for position, velocity and time.

--High anti-jamming immunity.

-- Simultaneous GPS, BeiDou 2-B3 and GLONASS.

-- Adaptive digital nulling, able to reject 6 independent jamming sources.

-- 96 hardware channels for simultaneous tracking of all visible satellite signals.

-- Integrated dual-channel L-band receiver.
