GPS Tri-Band Anti-Jamming Antenna
This product is a tri-band satellite navigation anti-jamming receiving antenna, featuring light weight, high integration and powerful anti-interference performance. It is suitable for receiving satellite navigation signals in complex environments such as airborne, vehicle-mounted and ship-borne scenarios
1. Main Features
Supported frequency bands: GPS-L1, GPS-L2, GPS-L5
Anti-jamming array configuration: Tri-band four-element anti-jamming design; each frequency band can suppress interference from up to 3 different directions
Anti-jamming capability (Jamming-to-Signal Ratio, JSR): 110 dB for single interference, 95 dB for three interferences within the same frequency band
2. Functions
Supports anti-jamming reception of three frequency signals simultaneously: GPS-L1, GPS-L2 and GPS-L5.
Each frequency band can counteract interference signals from a maximum of 3 directions. It can suppress typical interference types including wideband, narrowband, pulse, swept frequency, and any combination of the above signals.
Integrated GNSS full-band receiver (Model: ZED-X20P-00B), supporting multi-frequency or single-frequency positioning. The receiver model can be customized per customer requirements.
