GNSS technology has revolutionised many high-precision industries, such as agriculture, mining, and marine, as well as modern warfare. These applications depend on satellite technology for accurate positioning, navigation, and timing (PNT).
However, GNSS signals received on earth are weak and susceptible to interference and intentional jamming. A simple low-power jammer can overpower GNSS signals within a large area, denying PNT solutions.
GNSS anti-jam technology is quickly evolving. Until recently, size and cost considerations meant anti-jam systems were only feasible for expensive assets, such as strategic aircraft and capital ships. Advancements in low size, weight, and power (SWaP) and commercial availability have enabled more widespread adoption of anti-jam technology.
Hexagon | NovAtel's approach to the problem is to build a range of compact and affordable anti-jam systems for land, sea, air (including unmanned aerial systems), and fixed installations.
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.
GAJT is a null-forming system that preserves the antenna's view of the GNSS satellites while ignoring jammers, ensuring the satellite signals required to compute precise position remain available. GAJT works with any installed GNSS receiver and is ready for M-Code. The GAJT range of products provides anti-jam performance for every platform and is available off-the-shelf for rapid deployment.
The performance of GAJT is expressed as interference suppression and varies depending on the model. The performance is scenario-dependent, and the whole system performance is the sum of GAJT interference suppression plus that provided by the installed receiver itself.
GNSS Anti-Jamming Navigation Kit
The GNSS Anti-Jamming Navigation Kit consists of an array antenna, anti-jamming unit, and GNSS positioning unit. Dual Frequency8 Channel Anti-InterFerence Terminal is a compact satellitenavigation and anti-interference integrate system tailored for civiliandrones and industrial users.lt supports dual-frequency signal receptionof BeiDou-3 RNSS B1/B3 and features anti-wideband interference capability on Bl/B3 frequencies with a maximum interference tolerance ofup to 3 simultaneous interference source.Interally integrated with antenna arrays,anti-interference components,and satellite navigation re-ceivers,it serves reliable navigation in fields such as drones and un.manned vehicles,protecting user terminals from various unintentiona!interferences and malicious attacks,significantly enhancing PNT(Positioning,Navigation,and Timing)information security.
The array antenna is capable of receiving signals across 8 channels covering the B1I/B1C/L1 C/A/E1/G1 frequency bands for anti-jamming processing. The system supports simultaneous suppression of interference across up to seven B1I/B1C/L1 C/A/E1/G1 interference sources while maintaining GNSS positioning capability.
Supported interference types include narrowband, broadband, pulsed, swept-frequency, and combined interference.
The anti-jamming unit incorporates a polarization-, spatial-, temporal-, and frequency-domain anti-jamming processing algorithm. By integrating multidimensional characteristics across polarization, spatial, time, and frequency domains, the system provides effective suppression against various forms of GNSS interference.
The GNSS positioning unit supports the reception, decoding, and processing of multi-constellation and multi-frequency satellite signals, providing high sensitivity and high-accuracy positioning performance.
The overall system is designed to maintain stable operation in dynamic environments while providing strong anti-jamming performance under complex electromagnetic conditions. It outputs real-time, highly reliable PNT (Position, Navigation and Timing) information and can be integrated into various platforms requiring reliable navigation and positioning in challenging operational environments.
