WNS-950 Dual frequency Four Channels GNSS Anti-jamming System

Vista general

The anti-jamming system is designed to receive, amplify, down-convert, filter, and perform anti-jamming processing for 4 channels of BDS_B1，BDS_B2，GPS_L1 and GPS_L2 frequency signals. It operates on a power supply voltage of +12V to +32V. It is composed of composed of four main components: antenna array, RF component, anti-jamming processing component, and receiver. It can counteract three broadband jamming sources, providing high-precision positioning and accurate timing even under strong interference conditions. 4-channels：BDS_B1，BDS_B2，GPS_L1 and GPS_L2 antenna array ( Selectable frequency points: GLONASS_L1/ BDS_B3 ) B1: 1561.098MHz 2.046MHz； RF output power: -55dBm to -65dBm； Supports BDS, GPS, and GAL positioning, signal reception, decoding, and information output, providing time, position, and other parameters； Anti-jamming types: Capability to suppress various jamming types such as broadband, frequency sweep, pulse, and combination jamming； Multi-jamming resistance: Capable of countering 7 interference sources from different directions simultaneously； Nominal Wideband Suppression(Single direction): Jamming-to-signal ratio (JSR) 100dB@-130dBm； Nominal Wideband Suppression(Three directions): Jamming-to-signal ratio (JSR) 90dB@-130dBm； Broadband jamming suppression capability: 60dB； Operating temperature: -40℃ to +75℃； Storage environment: -45℃ to +80℃； Dimensions: (140.0 0.5)mm (140.0 0.5)mm (60 0.5)mm； Positioning accuracy: 10m； Velocity accuracy: 0.2m/s.
