Product Overview

The KGR-JRL1-65 is a high-performance four-channel GNSS anti-jamming and anti-spoofing system designed for high-precision positioning and timing scenarios under complex electromagnetic interference environments. Adopting professional RF signal processing and intelligent anti-interference algorithms, the device independently completes full-process signal processing including GNSS signal reception, amplification, down-conversion, filtering and interference suppression.

This system supports multi-system GNSS signal reception covering BDS, GPS and GLONASS, and focuses on high-efficiency anti-jamming protection for BDS_B1 and GPS_L1 core frequency bands. It can effectively suppress 3-channel broadband interference as well as sweep frequency, pulse and combined compound interference signals. Built with independent anti-spoofing capability, it thoroughly solves positioning failure and timing deviation caused by malicious jamming and deception attacks.

Featuring ultra-compact size, lightweight design and low power consumption, the KGR-JRL1-65 integrates four core components: antenna array, RF module, anti-interference processing unit and receiver module. It supports wide-range DC voltage input and standard serial port output, perfectly adapting to vehicle-mounted, UAV-borne, portable and fixed high-precision PNT (Positioning, Navigation and Timing) equipment integration.
