8 Elements Anti-Jamming Terminal

The product model is 8 Elements Anti-Jamming Terminal. It serves reliable navigation and timing applications in communication, transportation, finance, and power sectors, protecting user terminals from various types of unintentional interference, malicious attacks, electronic deception, and so on, significantly enhancing the security of PNT information.

The 8-element anti-jamming terminal produced by our company has the following core advantages: strong resistance to interference, extensive coverage, and a wide range of applications.
 

Principle: CRPA Adaptive Nulling Array with N elements can simultaneously suppress up to N-1 interference sources from different directions. An 8-element array can counteract up to 7 spatially independent interferences, compared to a 4-element array (maximally handling 3 interferences), significantly enhancing performance in multi-interference environments. Suitable for aircraft, UAVs, vessel and vehicle-mounted special platforms.

Custom Design • High RF Performance • Global Delivery

The antenna module is highly integrated with signal processing modules for BDS_B1, GPS_L1, GAL_E1, and GLO_G1 frequency points, featuring low noise figure, high gain, good array element consistency, and small mutual coupling. It adopts space-time joint adaptive anti-jamming technology, which can simultaneously counteract interference from seven different directions and combinations of different types. The 8 Elements Anti-Jamming Terminal is equipped with a high-performance ublox-F9P receiver, with the default protocol being the built-in UBLOX protocol. Users can use the ucenter software for adaptive configuration.

1. Simultaneous suppression of multiple interference sources, strong adaptability to complex electromagnetic environments

It can simultaneously perform spatial nulling on interference signals from seven different directions, suppressing multi-path jamming from all sides (broadband, narrowband, swept-frequency, pulse, and combined interference).

In high-density electromagnetic jamming scenarios with multiple interfering devices operating simultaneously, the system does not fail directly due to the large number of jamming sources. However, a 4-element array can only handle up to 3 jamming signals at a time, leading to a sharp decline in performance or even failure in locating 4 or more jamming sources.

It provides 360° all-round, large elevation range airspace filtering with zero-stabilization compensation for carrier attitude changes (aircraft maneuvers, UAV rolls, vehicle jolts).

2. Better airspace filtering performance with less satellite signal loss

The space-time adaptive(STAP) beamforming algorithm is employed to deeply nullify interference directions while forming a gain beam for useful satellite signals, effectively suppressing interference while preserving weak GNSS satellite signals as much as possible.

With higher zeroing accuracy, it is less likely to "misidentify" valid satellite signals when the interference source is close in angle to the satellite signal, compared to low-element products, ensuring satellite reception count and positioning continuity.

Under single-path interference, the interference suppression depth is high, and positioning, speed measurement, and timekeeping outputs remain stable even in strong interference environments.

3. Compatible with multiple platforms, robust in motion carrier performance

Suitable for high-maneuverability airborne platforms, drones, and high-speed special vehicles: The carrier can rapidly change its attitude; the array has high degrees of freedom, enabling quick self-adaptive re-zeroing, and is less prone to positioning jumps or brief loss of lock during maneuvering.

Supports multi-system and multi-frequency points for BeiDou, GPS, Galileo, and GLONASS, with dual-frequency/multi-frequency anti-jamming capabilities, while also possessing a certain level of resistance to navigation spoofing signals.

It supports wide voltage power supply, wide temperature range operation (- 45℃ to +70℃), meeting the stringent requirements of airborne and vehicular environments.
 

• Used for aircraft and drones: Resist GNSS (satellite navigation) interference and spoofing, ensuring aircraft positioning, velocity measurement, and time synchronization. In hostile electromagnetic interference environments, maintain position information without loss, supporting flight navigation and approach landing.
   
• Used for vehicles and autonomous vehicles: Vehicles rely on BeiDou/GNSS for positioning, speed measurement, and time synchronization. Resist suppression interference from external jammers, prevent navigation signals from being blocked, and ensure the vehicle does not lose its position;
   
• Used for boats and yachts: Ship navigation, avoidance, port entry and exit, and anchoring height rely on satellite navigation.Resist suppression interference: prevent navigation signals from being blocked by noise interference, avoid positioning loss and track disappearance. Resist navigation deception and interference: prevent false navigation signals from tampering with the ship's position, avoid ship deviation and entering dangerous waters by mistake;Stable output of position, speed, and time information is available in offshore, nearshore, and port areas, supporting the normal operation of ship automatic identification system(AIS) and electronic chart system.
