Antennas for the Navigation Systems

Anti-jamming Satellite Navigation System Receiver

Product Description:
BDS/GPS/GLONASS airborne anti-jamming device can simultaneously receive satellite signals of BDS B3, GPS L1 and GLONASS L1 frequency points. The self-adaptive filtering technology points the null direction of the array combining pattern to the direction of the interference, and the beamforming technology is used to direct the high gain direction of the array combining to the direction of the effective satellite, so as to suppress the interference and improve the satellite collection performance. In the complex electromagnetic environment, when the ordinary satellite navigation system loses the positioning ability, the anti-jamming antenna can still receive the navigation satellite signal normally, and realize the real-time positioning, speed measurement and timing of the missile body. The airborne anti-jamming device can simultaneously resist multiple suppressive interference, including continuous wave, frequency sweep, pulse, narrowband, broadband, etc.

Multi-frequency anti-jamming: can realize anti-jamming processing of BDS B3, GPS L1 and GLONASS L1 at the same time
Integrated design: The anti-jamming processor can be integrated according to the reserved space of the carrier
Online phase correction: support online phase correction
Star collection performance: Use multi-azimuth beamforming technology to maximize the star collection performance in non-interference directions
Interface configuration: Through the configuration interface, various anti-interference parameter configurations, program programming, fault detection, selection of channel signal pass-through, output signal strength, detection of interference and interference strength can be performed through the configuration interface.
Anti-vibration shock: strong ability to withstand shock and vibration, stable and reliable performance
Military-grade quality: strong environmental adaptability, meeting the requirements of military-grade equipment
