BNTTIM GNSS Anti Jamming Module: 3-Channel 105dB Guard

Ultra‑Compact GNSS Anti Jamming Module for Demanding Platforms

The BNTTIM GNSS anti jamming module is a miniature navigation terminal built for UAVs, electronic warfare systems, and communication base stations. With a footprint of just 65×65×30mm and a weight of 185g, this unit directly replaces most standard aviation or vehicle antennas. It processes GPS‑L1, BDS‑B1, and GAL‑E1 signals while actively suppressing broadband, narrowband, swept‑frequency, pulsed, and combined interference patterns.

This GNSS anti jamming module integrates a 4‑element antenna array, anti‑jam circuitry, and an M10S receiver into a single low‑cost, lightweight enclosure. It delivers reliable positioning in electromagnetically contested environments – a critical advantage for drone operations where size and power are tightly constrained.

Superior Jammer Suppression in a Tiny Package

Despite its small dimensions, the BNTTIM GNSS anti jamming module handles up to three simultaneous jammers arriving from distinct directions. Single‑interference rejection exceeds 105dB, while triple‑jammer suppression reaches ≥85dB. These figures place it among the most capable ultra‑light anti‑jam solutions available today. The module effectively counters typical threats like continuous wave tones, chirp sweeps, and impulsive noise – often encountered near radar sites or communication relays.

Integrated M10S Receiver and Dual RS232 Outputs

At the core of this GNSS anti jamming module lies the M10S receiver, a modern chipset offering fast acquisition and stable tracking across all three supported bands. Data output uses two independent RS232 ports (default 115200 baud) with NMEA0183 protocol. This dual‑serial design allows simultaneous streaming to flight controllers and telemetry systems, simplifying integration without additional multiplexing hardware.

Power Efficiency and Mechanical Flexibility

The BNTTIM GNSS anti jamming module accepts a wide 9‑36Vdc input and consumes only 7.5W nominal power – a key benefit for battery‑powered UAVs. Its operating temperature range spans -40°C to 70°C, ensuring functionality in arctic cold or desert heat. Four Φ2.8mm mounting holes on a 59.7×59.7mm grid enable direct drop‑in replacement for existing antenna footprints, minimising mechanical redesign efforts.

Deployment Scenarios for the BNTTIM Module

• Unmanned Aerial Vehicles – Maintains precise GNSS lock during low‑altitude flights near urban towers or military training zones.

• Electronic Countermeasure Pods – Provides resilient navigation for airborne jammer platforms that operate in dense signal environments.

• Tactical Ground Stations – Protects static and mobile command posts from accidental or adversarial interference.

• 5G Communication Synchronisation – Supplies stable 1PPS timing derived from jam‑free GNSS, protecting network handover integrity.
