As drone technology proliferates and electromagnetic environments grow increasingly complex, ensuring the integrity of Positioning, Navigation, and Timing (PNT) data has become a core challenge for defense, energy, transportation, and other sectors. BNT Technology has officially released its new-generation anti‑jamming antenna product line – the BNT2511 16‑Element Anti‑Jamming Antenna and the BNT8AT 8‑Element Anti‑Jamming Antenna – delivering robust GNSS positioning through advanced array signal processing technologies.
BNT2511: 16‑Element Anti‑Jamming Antenna for Extreme Electromagnetic Threats
The BNT2511 is an all‑in‑one solution integrating a 16‑element anti‑jamming array, a multi‑constellation receiver, and RF front‑end. Its key strengths include:
-
Superior Interference Suppression: With 16 independent processing channels, it can form spatial nulls against up to 15 simultaneous jammers. Test data shows a jamming‑to‑signal (J/S) ratio of 100 dB against a single interferer, and still maintains 70 dB against 15 interferers, effectively countering narrowband, broadband, pulsed, swept, and Gaussian jamming.
-
Multi‑System Compatibility and High Precision: Fully supports GPS L1, GAL E1, and BDS B1 (including B1c and B1i civil signals). In jamming‑free conditions, horizontal and vertical positioning accuracy both reach ≤1.5 m (95%) ; under active jamming, it maintains ≤10 m positioning accuracy, with velocity accuracy ≤0.2 m/s and timing accuracy ≤100 ns.
-
Integrated Compact Design: A built‑in high‑sensitivity receiver (u‑blox ZED‑F9P) eliminates the need for an external positioning module, simplifying cabling. Dimensions are only 230×230×24 mm, weight ≤1250 g, power consumption ≤25 W, and it accepts 12‑32 V DC input, making it ideal for medium‑sized UAVs, ground vehicles, and fixed installations.
-
Environmental Robustness: Operating temperature range from ‑40°C to +55°C, meets GJB150A rain requirements, includes overvoltage/reverse‑polarity protection, and withstands ≥10 W continuous‑wave interference. Firmware can be upgraded in the field via serial port for easy long‑term maintenance.
BNT8AT: 8‑Element Anti‑Jamming Antenna – Balancing Lightweight and High Performance
For platforms more sensitive to size, weight, and power (SWaP), BNT Technology simultaneously introduces the BNT8AT 8‑element anti‑jamming antenna. This product delivers excellent interference suppression while achieving extreme miniaturization.
-
Efficient Interference Suppression: With an 8‑element array, it can form up to 7 spatial nulls simultaneously. J/S ratio reaches ≥110 dB against a single jammer and remains ≥90 dB against seven interferers, effectively securing GPS L1 and GLONASS G1 signal reception.
-
Compact and Lightweight: Ultra‑thin housing of 150×150×22.5 mm, weight under 720 g, power consumption only 19 W, supports 8‑34 V wide input, perfectly suiting small‑to‑medium UAVs, unmanned ground vehicles (UGVs), and man‑portable equipment.
-
Flexible Output Options: Provides both TTL serial (NMEA or UBX protocol) and SMA RF output interfaces. Users can choose direct connection to flight controllers or external GNSS receivers based on system architecture, and firmware upgrades are supported in the field.
-
Rugged and Reliable: Operating temperature from ‑40°C to +70°C, meets GJB150A environmental standards, with MTBF of 3000 hours, suitable for long‑term deployment in harsh environments.
About BNT Technology
Founded in 2006, BNT Technology is a leading global manufacturer of RF and microwave modules, specializing in high‑power drone jammer solutions and high‑end anti‑jamming antenna technologies.
