We focus on the research and industrialization of comprehensive PNT navigation countermeasure technologies, concentrating on the "wireless trusted PNT" direction. Addressing the core pain points of satellite navigation vulnerability to interference, deception, obstruction, and denial, we precisely meet the trusted navigation, positioning, and timing needs of key industries, providing comprehensive anti-interference and anti-deception solutions and related products for complex electromagnetic env
In recent years, cases of deception or interference with Global Navigation Satellite Systems (GNSS, such as GPS, BeiDou, GALILEO, GLONASS, etc.) have been increasing internationally.
Satellite navigation deception and interference is a technique that induces receiving equipment to calculate incorrect position, velocity, or time information by transmitting false satellite navigation signals. Unlike simple and crude suppression interference, deception and interference are more covert and dangerous. It does not interrupt the user's navigation signals but quietly rewrites their positioning data. Intermittent or continuous deception and interference can cause incalculable real or potential harm in severe cases.
We focus on the research and industrialization of comprehensive PNT navigation countermeasure technologies, concentrating on the "wireless trusted PNT" direction. Addressing the core pain points of satellite navigation vulnerability to interference, deception, obstruction, and denial, we precisely meet the trusted navigation, positioning, and timing needs of key industries, providing comprehensive anti-interference and anti-deception solutions and related products for complex electromagnetic environments. Among its core businesses, "Perception and Defense" is one of the main focuses, concentrating on the detection, alarming, and interference source location of satellite navigation spoofing interference. It provides systematic solutions, specifically encompassing three categories: dedicated spoofing detection products, integrated detection and positioning products, and anti-interference and anti-spoofing products. These products can be systematically configured according to actual application scenarios to achieve the most cost-effective navigation spoofing detection and spatiotemporal security protection.
The dedicated spoofing detection products address the needs of satellite navigation spoofing interference detection and alarming in key areas. They provide dedicated spoofing interference detection products for satellite navigation signals, covering commonly used satellite navigation frequencies and expandable as needed. They are compatible with various platforms, including portable, vehicle-mounted, airborne, shipborne, and networked distributed platforms. These products can be applied to integrated air-ground satellite navigation spoofing interference detection, alarming, interference source location, and investigation scenarios at fixed sites (which can be deeply integrated with mobile communication base stations, smart light poles, etc.), vehicle-mounted mobile stations, and airborne platforms in key areas.
Anti-interference and anti-spoofing products are designed to meet the reliable positioning and timing needs of satellite navigation. They offer timing security isolation and protection, airborne miniaturized dual-anti-interference receivers, multi-element anti-interference and anti-spoofing integrated terminals, and other anti-interference and anti-spoofing terminals. These products can be widely used in various infrastructures and mobile platforms for BeiDou anti-interference and anti-spoofing positioning and timing. In applications on various mobile platforms such as UAVs, they can collaborate with dedicated spoofing detection products to build an "air-ground integrated" spoofing interference detection and interference source location system, enabling the location and investigation of satellite navigation interference sources in complex urban environments.
