,Lightweight Portable Spoofing Signal Source
In an era where GNSS reliability is threatened by jamming and spoofing, ensuring the resilience of navigation systems is critical. For applications like reference networks and drone surveillance, the degradation or loss of GNSS signals can be catastrophic.
Jamming is a interference of the GNSS signals caused by the emission of radio frequency noise. This can lead to loss of the navigation and timing information provided by GNSS receivers, affecting their accuracy and reliability.
Spoofing occurs when a malicious attacker feeds wrong signals into a GNSS receiver to hijack its positioning output. Spoofing is a “smart” form of GPS interference. During a spoofing attack, the GPS receiver reports wrong positioning
Anti jamming GNSS systems are advanced solutions designed to detect, suppress, and mitigate intentional or unintentional interference, ensuring reliable positioning, navigation, and timing even in highly contested environments. As GNSS disruptions become more frequent worldwide, these technologies have shifted to a critical component across defense, aviation, maritime, and autonomous systems.
GNSS Anti-Jamming Navigation Kit
The GNSS Anti-Jamming Navigation Kit represents a complete end-to-end solution for maintaining accurate positioning and timing in heavily contested electromagnetic environments. Comprising an array antenna, an anti-jamming processing unit and a multi-constellation GNSS receiver, the system is specifically engineered to overcome the limitations of standard GNSS receivers when faced with intentional or unintentional interference.
Equipped with an 8-channel array antenna, the kit receives signals in the B1I, B1C, L1 C/A, E1 and G1 bands and can simultaneously null up to seven independent interference sources. It effectively counters a broad spectrum of interference types, including narrowband, broadband, pulsed, swept-frequency and combined forms of jamming. This capability ensures that the system continues to deliver usable satellite signals even under severe interference conditions.
The anti-jamming unit utilizes an advanced multi-domain processing algorithm that jointly exploits polarization, spatial, temporal and frequency characteristics of the received signals. This multidimensional approach enables precise interference suppression while safeguarding the quality of the desired GNSS signals. The integrated GNSS positioning unit supports multi-constellation and multi-frequency reception, decoding and processing, delivering high-sensitivity and high-accuracy positioning results. Designed for stable performance in dynamic environments, the kit provides continuous, highly reliable PNT information and can be readily integrated into platforms that demand dependable navigation under complex operational conditions.
