CHREDSUN 65×65mm 4-Element Anti-Jamming Antenna – High-Performance GNSS Navigation Solution for Electromagnetic Contested Environments

Meta Description:

CHREDSUN's 65×65mm 4-element anti-jamming GNSS antenna delivers superior jamming suppression up to 105dB, supporting BeiDou B1, GPS L1, Galileo E1, and GLONASS G1. Compact, lightweight, IP65 rated for harsh environments. Ideal for military UAVs, commercial drones, and critical infrastructure.

Overview

In today's complex electromagnetic environments, reliable satellite navigation is critical. The CHREDSUN 65×65mm 4-Element Anti-Jamming Antenna is meticulously engineered for robust GNSS signal reception, even under heavy jamming conditions.

Equipped with a 4-channel antenna array, this anti-jamming device simultaneously suppresses up to three jamming sources, including broadband, swept-frequency, and pulse interference. It supports multi-GNSS constellations, providing redundant and reliable positioning for mission-critical applications.

Key Features and Benefits

• Advanced Multi-Source Jamming Suppression: Effectively counteracts 1-3 simultaneous wideband, swept, and pulse jamming sources with jammer-to-signal ratios reaching 105dB (single-source) and 95dB (multi-source).

• Comprehensive Multi-GNSS Support: Compatible with BeiDou B1C/B1I, GPS L1C/A, Galileo E1, and extended GLONASS G1 frequencies for ultimate positioning reliability.

• Flexible Dual Operation Modes: Switch between Anti-Jamming Antenna Mode (clean RF output) and Built-in Receiver Mode (direct PVT solutions), simplifying system architectures.

• Compact and Lightweight Design: Measures just 65×65×23mm, weighs less than 150g, and consumes ≤6W power on a 9V-32V DC supply—perfect for drones and compact platforms.

• Robust Environmental Resistance: Operating temperature range from -40℃ to +70℃, IP65 ingress protection rating, and over 2000 hours MTBF ensure high reliability in demanding conditions.

Ideal Applications

• Military UAVs, precision-guided munitions, and ground vehicles operating in contested electromagnetic fields.

• Commercial drones, aerial surveying, emergency response vehicles requiring uninterrupted GNSS services.

• Critical infrastructure security including power grids and communication networks.

• Research platforms and specialized unmanned systems needing high-precision anti-jamming navigation.
