BNTLS8 Signal Anti Jamming Module: 7-Jammer 110dB Supreme Guard

Eight-Element Signal Anti Jamming Module for Maximum Protection

The BNTLS8 signal anti jamming module represents the pinnacle of GNSS interference protection, engineered for environments where multiple jammers threaten navigation integrity. Featuring an eight-element antenna array and quad-band coverage across L1, B1, G1, and E1 frequencies, this unit supports GPS, BeiDou, GLONASS, and Galileo systems. What sets this signal anti jamming module apart is its capacity to handle up to seven simultaneous jammers—a capability unmatched by conventional four-element designs.

Eight-Element Array: The Advantage of More Elements

The eight-element array provides additional spatial degrees of freedom, allowing the signal anti jamming module to null more interference directions while preserving satellite visibility. With more antenna elements, the module creates deeper nulls and sharper beam patterns, resulting in superior rejection performance. This extra element count directly translates to the ability to handle seven distinct jammers, making the BNTLS8 the go-to choice for high-threat environments such as electronic warfare zones, contested airspace, and dense urban deployments.

Seven-Jammer Suppression Capability

Where most anti-jamming solutions top out at three or four jammers, the BNTLS8 signal anti jamming module pushes the limit to seven simultaneous interferers from different directions. Single-jammer suppression reaches ≥110dB, triple-jammer rejection stands at ≥95dB, and even with seven active jammers, the module maintains ≥85dB suppression. It effectively counters broadband noise, narrowband tones, pulsed spikes, swept-frequency chirps, and combinations of these patterns—ensuring continuous positioning regardless of the complexity of the jamming environment.

Integrated X20P Receiver and Versatile Interfaces

At the core of this signal anti jamming module sits the Ublox X20P receiver, a high-sensitivity chipset that delivers rapid acquisition and stable tracking across all four constellations. Data output is supported via RS422 (default 115200 baud) for robust long-distance communication and UART at LVTTL 3.3V levels for direct embedded integration. Both interfaces output NMEA0183 protocol, simplifying connection to flight controllers, ground stations, or telemetry systems. A dedicated 1PPS pin (LVTTL 3.3V) provides precise timing synchronisation for external equipment.

Mechanical Design and Environmental Resilience

The BNTLS8 signal anti jamming module accepts a wide 9-36Vdc input and consumes 18W nominal power. Weighing 670g, it features a low-profile enclosure measuring 170×150×20±0.5mm—ideal for ground vehicles, fixed installations, marine platforms, and airborne applications. The operating temperature range spans -40°C to 70°C, ensuring reliable performance in extreme climates. Four Φ4.2mm mounting holes on a 160×120mm grid enable straightforward mechanical integration.

Typical Deployment Scenarios

• Electronic Warfare & Defence Systems – Handles dense jamming environments with up to seven simultaneous interferers across all four GNSS bands.

• Critical Infrastructure Protection – Safeguards GNSS timing and positioning for power grids, telecom networks, and data centres.

• High-Threshold UAV Operations – Supports drone missions in contested airspace where multiple jamming sources are expected.

• Marine Navigation – Provides dependable positioning for naval vessels operating near electronic countermeasure zones.
