Core Advantages & Differentiators
Industry-Leading Dual-Frequency Anti-Interference Performance
At the heart of this dual-frequency satellite navigation anti-jamming terminal is its exceptional interference suppression capability, with an ISR of ≥105dBc for single interference and ≥95dBc for up to three simultaneous broadband interferences. This industry-leading performance ensures uninterrupted positioning in the most challenging environments, from busy urban corridors to high-electromagnetic-interference mining and port sites.
Advanced Anti-Spoofing Protection for Critical Operations
Unlike basic anti-jamming solutions, this high-performance anti-spoofing antenna for ground vehicles features robust anti-spoofing technology, with an output residual spoofing signal CN0 of ≤20dB. This capability effectively detects and mitigates malicious spoofing attacks, protecting critical industrial operations from signal manipulation and unauthorized positioning control.
Dual-Frequency Multi-Constellation Reception
The terminal supports simultaneous dual-frequency reception for BDS B1i (1561.098MHz) and GPS L1 (1575.42MHz) constellations, delivering enhanced positioning accuracy, faster signal acquisition, and improved reliability in complex environments compared to single-frequency solutions.
Rugged Design for Industrial Vehicle Environments
Engineered for harsh ground vehicle operations, this BDS GPS anti-jamming system for fleet defense features a compact 150mm × 130mm × 22mm form factor and ≤520g weight, with a rugged build optimized to withstand vehicle vibration, temperature fluctuations, and harsh outdoor conditions. It provides full 0°360° azimuth and -90°90° pitch anti-interference coverage, ensuring consistent protection in all driving scenarios.
Industrial Applications & Use Cases
The 4CH TX2501-AJS-DPA anti-jamming anti-spoofing antenna is optimized for ground-based industrial applications where secure, reliable PNT is mission-critical. Key use cases include commercial and special ground vehicle fleets for logistics and security operations, autonomous guided vehicles for port and mining automation, critical infrastructure timing synchronization for power grids and communication towers, long-range industrial UAVs for surveying, law enforcement emergency response vehicles, and fixed-site security systems for critical facility protection.
