System Spoofing and Interference Capability

Coverage Range

For airspace below 500 m altitude:

Omnidirectional navigation spoofing distance ≥ 30 km

Directional navigation spoofing distance ≥ 50 km

For high-altitude airspace above 1500 m:

Directional navigation spoofing distance ≥ 100 km

Interference Capability Against Military GNSS Receivers

Although the system cannot perform actual spoofing against military GNSS receivers, it can effectively interfere with military satellite navigation equipment that uses encrypted codes, such as GPS P-code, M-code, BeiDou encrypted signals, etc.

The system can suppress these military signals, causing the equipment to be unable to perform real-time positioning and forcing it to stop outputting location data.

Interference Capability Against GNSS-Inertial Integrated Navigation

Because the system has a relatively wide coverage range, it can interfere with navigation equipment that relies on the combination of satellite navigation and inertial navigation.

Since the system denies the satellite positioning corrections necessary for inertial navigation error compensation, it significantly reduces the accuracy of such integrated navigation systems.

Adaptability in a Spoofed GNSS Environment

When satellite navigation signals are interfered with or spoofed by third parties, the system can still operate properly.

By using network time service, star ephemeris data, and other auxiliary methods, the system maintains stable operation and is not affected by interference or spoofing.

Deployment Adaptability

Whether the system is deployed on a fixed platform or a mobile platform, it can operate stably in both scenarios.

Methods for Breaking Through GNSS Anti-Jamming Technologies

Civil GNSS Receiver + CRPA Anti-Jamming Antenna Scenario

For civil GNSS systems equipped with CRPA (Controlled Reception Pattern Antennas) Anti-Jam antennas:

The system can impose a relatively good suppression effect on conventional jamming.

However, its suppression against Spoofer signals is weak.

By increasing the transmitted power, it is still possible to achieve satisfactory interference effectiveness.

Military GNSS Receiver + CRPA Anti-Jam Scenario

Although military encrypted devices cannot be spoofed, the Spoofing signal and military encrypted GNSS signals have high spectral similarity, enabling the system to achieve relatively good interference effects.

The interference performance is significantly better than noise jamming, barrage jamming, sweep jamming, etc.

Deploying multiple Spoofers in a circular formation, transmitting signals from multiple directions simultaneously, achieves a better suppression effect.

In general, three devices distributed circumferentially can achieve good results.

Anti-Spoofing Receiver + CRPA Anti-Jam Scenario

If the user deploys both Anti-Spoofing receivers and CRPA Anti-Jam antennas, the system can significantly suppress both Anti-Jamming filtering and Anti-Spoofing identification.

Using multiple Spoofers deployed in a circular formation, transmitting Spoofing signals from multiple directions simultaneously, can still effectively suppress such advanced receivers.

Typically, two devices in a circular configuration can achieve good results.

Typical Application Scenarios

Navigation Spoofing Against UAVs
The system is capable of spoofing UAVs that rely on satellite navigation positioning, which may cause the UAV to lose control and crash.
Navigation Spoofing Against Unmanned Surface Vessels (USV)
The system can spoof unmanned vessels that rely on satellite navigation, enabling operators to redirect or manipulate the vessel into circling or deviating from its intended route.
Navigation Spoofing Against Maritime Vessels
The system can spoof vessels navigating at sea, preventing them from acquiring accurate positioning or causing them to obtain incorrect coordinates, resulting in loss of direction and navigational deviation.
Construction of GNSS-Denied Zones
By using omnidirectional or directional spoofing modes, the system can establish GNSS-denied environments within designated areas.
