Anti-Jamming GNSS Antenna for Drones, Communication Networks

CHREDSUN 100×100mm 4-Element Anti-Jamming GNSS Antenna – Ensuring Precise GNSS Navigation in Challenging Electromagnetic Environments

CHREDSUN's compact 100×100mm 4-element anti-jamming GNSS antenna supports BeiDou B1, GPS L1, Galileo E1, and extended GLONASS G1. With superior jamming suppression up to 110dB and IP65 protection, it is designed for military UAVs, commercial drones, and critical infrastructure requiring uninterrupted satellite navigation.

Product Highlights

The CHREDSUN 100×100mm 4-Element Anti-Jamming Antenna is engineered to maintain stable satellite signal reception in highly contested electromagnetic fields. It effectively counters 1 to 3 simultaneous sources of broadband, frequency-sweeping, pulse, and other types of jamming across BeiDou, GPS, Galileo, and GLONASS signals. Thanks to advanced array technology, this antenna ensures steadfast positioning reliability even under complex interferences.

Key Advantages

Powerful Anti-Jamming: Jamming-to-signal ratios reach up to 110dB for single broadband sources and 100dB for three broadband sources simultaneously.

Multi-GNSS Support: Full compatibility with BDS B1C/B1I/B1A, GPS L1C/A, Galileo E1, and extended GLONASS G1 ensures redundant and accurate positioning.

Dual Operation Modes: Switchable between Anti-Jamming Antenna Mode with clean RF output and Built-in Receiver Mode producing full PVT solutions, simplifying integration.

Compact & Efficient: Dimensions of 100×100×25mm, weighing less than 300g, with low power consumption (≤10W) for installation on size- and power-limited platforms.

Reliability & Ruggedness: IP65 waterproof rating, operating temperatures from -40℃ to +70℃, and mean time between failures over 2000 hours guarantee durability in harsh conditions.
