GNSS Anti-jamming System

(Multi Constellation/Frequency Anti-jamming System)

Product Overview

Joint space-time processing technology is adopted to break through the limitations of time-domain processing and space-time processing anti-jamming algorithm, increases the freedom of the array without increasing the array elements, and can suppress the interference in space and time two dimensional at the same time. It has the ability to resist the wideband and narrow band jamming signals of GPS L1, GLONASS R1 and BDS B1 simultaneously.

Product Composition

The product is composed of array antenna, anti-jamming processor and supporting cable. The anti-jamming processor is composed of three independent anti-jamming modules (GPS, GLONASS, and BDS) and power module.

Features

· Four element array antenna to anti 3 jammers simultaneously.

· Adopting pace-time adaptive anti-jamming processing algorithm, and has the anti-jamming ability of GPS L1, GLONASS R1 and BDS B1 simultaneously, support GPS L2, GLONASS R2 and BDS B3.

· Single RF cable connection between anti-jamming unit and array antenna, separated cable adjustable.

· Computer controllable and configurable, and each frequency switchable through peripheral communication interface.

· Each frequency adopts independent module design, which is convenient for maintenance and repair.

· Small size, light weight, easy to install.
