Product Description

Product Overview

The CHREDSUN 150×150 mm 16‑Element Anti‑Jamming Antenna is a high‑performance GNSS front‑end designed to keep positioning and timing services available in heavily contested RF environments. With an integrated 16‑element array, advanced anti‑jamming processing and optional built‑in GNSS receiver, it delivers resilient navigation for defense, aviation, maritime and critical infrastructure applications.

The antenna receives, filters and processes BDS B1, GPS L1, Galileo E1 and optionally GLONASS G1 or BDS B3, suppressing up to 15 simultaneous jamming sources from any direction. Powered over a wide 9–36 V DC input and housed in a compact 150×150×24 mm IP65 enclosure, it is ideal for new designs and retrofit upgrades where GNSS robustness is mandatory.

Key Features & Benefits

16‑element CRPA‑type array for spatial filtering and deep jamming suppression in B1/L1/E1 (extended G1) or B3 bands.
Up to 15 concurrent interferers rejected, including broadband, narrowband, sweep and pulse jamming scenarios.
Integrated anti‑jamming processor + optional GNSS receiver, supporting both RF‑front‑end mode and full PVT output mode.
High jamming‑to‑signal resilience:

Single broadband: J/S ≥ 105 dB @ –130 dBm
Three broadbands: J/S ≥ 95 dB @ –130 dBm
Fifteen broadbands: J/S ≥ 80 dB @ –130 dBm

Full sky protection with 0°–360° azimuth and –90° to +90° elevation coverage for jamming suppression.
Embedded receiver accuracy: horizontal ≤ 7 m, vertical ≤ 9 m (95%), velocity ≤ 0.2 m/s (95%).
Ruggedized design: –40 °C to +70 °C operating range, IP65 or better ingress protection, MTBF ≥ 2000 h.
Flexible integration via SMA‑K RF connector and J30J‑15ZKP power/data interface with serial configuration.
