NTGIM-4B Multi-Constellation GNSS Anti-Jamming Overview
The NTGIM-4B Satellite Navigation Anti-Jamming All-in-One is a high-performance navigation terminal targeting application scenarios such as UAVs, automated platform protection, and communication base stations. It achieves anti-jamming processing for interference forms including broadband, narrowband, frequency-sweeping, pulse, and combined jamming at GPS-L1/BDS-B1/GLONASS-L1 frequency points. This product integrates a 4-element antenna array, anti-jamming module, and navigation receiver into one unit. Adopting a low-cost, miniaturized, and lightweight design, it is suitable for precise navigation needs in complex electromagnetic environments, with outstanding performance especially in the UAV field.
NTGIM-4B Multi-Constellation GNSS Anti-Jamming Primary Capabilities
- Comprehensive Multi-System Tracking: Delivers robust signal tracking compatibility across diverse frequency links including GPS-L1, BDS-B1, GLONASS-L1, and Galileo-E1 bands.
- High-Attenuation Nulling Thresholds: Restores positioning continuity by executing spatial nulls reaching single interference ≥110dB and three concurrent interferences ≥95dB.
- Concurrent Multi-Directional Shielding: Isolates and suppresses high-power radio frequency threats arriving from up to 3 different directions simultaneously.
- Broadband and Pulse Signal Filtering: Dampens continuous and transient suppressive jamming signals such as broadband noise, narrowband carrier lock, frequency-sweeping, and combined emissions.

NTGIM-4B Compact Enclosure Mechanical Dimensions / Structural Profile
The mechanical housing architecture of the terminal is defined by a low-profile envelope measuring 132mm×132mm×20mm with a strict dimensional tolerance of ±0.5mm. Weighing 480g, the fully shielded metal assembly provides integrated protection for internal sensor chipsets while maintaining a low weight impact. Secure fixed hardware mounting is established through 4x Φ3.2mm layout through-holes arranged symmetrically at a grid spacing of 125mm×125mm, enabling rigid direct platform interface lock-down.
