Dual frequency eight channel anti-interference terminal(CRPA)

1. Product Overview

The BGS-009-8CH-BD-WG-DT Dual-Frequency Eight-Channel Anti-Jamming Terminal is a highly integrated satellite navigation anti-jamming unit designed for civilian UAVs and industrial users. This product supports dual-frequency signal reception for BeiDou-2/3 RNSS B1/B3 and GPS L1, and features powerful anti-jamming capabilities capable of suppressing up to 3 interference sources. It integrates an antenna array, anti-jamming processing components, and a satellite navigation receiver internally. Suitable for intelligent mobile platforms such as UAVs, UGVs, and USVs, it effectively resists both unintentional interference and malicious attacks, significantly enhancing the security and reliability of Positioning, Navigation, and Timing (PNT) systems.

2. Core Functions

1. Dual-Frequency Eight-Channel Anti-Jamming
   Supports dual-system (BeiDou & GPS) and dual-frequency signal processing with 8-channel parallel processing capability, adapting to complex electromagnetic environments.
2. Multi-System RNSS Signal Reception
   Compatible with BeiDou-2, BeiDou-3, and GPS systems, supporting civilian codes BIC, B31, and L1C/A signal reception.
3. Strong Anti-Jamming Capability
   Effectively suppresses various types of jamming including narrowband, broadband, pulsed, swept-frequency, and Gaussian jamming. Single-interference jamming-to-signal ratio ≥95dB; triple-interference jamming-to-signal ratio ≥85dB.
4. Built-in Navigation & Positioning Module
   Integrates a full-frequency navigation and positioning module, outputs data in NMEA0183 protocol via serial port or RF interface.
5. Software Upgradability
   Supports software upgrades for both the receiver and anti-jamming modules via serial port, facilitating functional expansion and performance optimization.
6. System Self-Test and Protection
   Features system self-test and status monitoring functions. Provides over-voltage protection, reverse-connection protection, and resists continuous wave power of no less than 10W, ensuring good safety and reliability.
