Product Description

Product Overview

The CHREDSUN 230×230 mm Dual 16‑Element GNSS Anti‑Jamming Antenna is a high‑performance, low‑cost solution designed for platforms that demand robust, multi‑band protection against GNSS interference and jamming.

With two 16‑channel arrays and a built‑in GNSS receiver, this module simultaneously processes BDS B1 / GPS L1 /

Galileo E1 plus GPS L2 or GPS L5, delivering resilient positioning even in environments with up to 15 jammers from different directions. It is ideal for UAVs, manned aircraft, vehicles, maritime systems and critical infrastructure that require dual‑band GNSS and enhanced PNT resilience.

Key Features

Dual‑band, dual 16‑channel design: 16‑channel B1/L1/E1 + L2 or 16‑channel B1/L1/E1 + L5, with integrated anti‑jamming processing and PVT solution output.
High anti‑jamming performance: suppresses 1–15 wideband, sweep and pulse jamming sources across both bands, with SIR up to 105 dB at –130 dBm for single‑direction interference.
Built‑in GNSS receiver: outputs static position and velocity after anti‑jamming processing, so the antenna can act as both a protected RF front‑end and a complete navigation unit.
Rugged 230×230 mm housing: ≤25 mm height, ≤1.5 kg, IP65 waterproof rating, designed for harsh environments and tested to GNSS/UAV shock and vibration standards.
Flexible interfaces: J30J‑15ZKP power/data connector (RS422 + dual RS232 channels) and dual SMA‑K RF outputs for the two frequency bands.
Wide input voltage & low ripple: 9–36 V DC (nominal 12 V) with ≤100 mV ripple, average power consumption ≤50 W.
