Product Description

Product Overview

This 16-element anti-jamming antenna is a high-performance GNSS front-end device designed to maintain positioning and timing services even in contested environments with complex RF conditions. Integrating a 16-element antenna array with advanced anti-jamming processing technology—and offering an optional built-in GNSS receiver—it delivers robust navigation capabilities for industrial and agricultural drones, unmanned ground vehicles, mobile mapping systems, marine equipment, robotics, and other civilian autonomous platforms that rely on reliable position, velocity, and timing data.

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 200 x 200 x 26 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.
