The anti-interference system is designed to receive, amplify, down-convert, filter, and perform anti-interference processing on the GPS L1 and GLONASS L1 frequency signals of 4 channels.
It is powered by +5V voltage and consists of three parts:
antenna array component, RF component, and anti-interference processing component. It can resist three broadband
interference sources and provide high-precision positioning and precise timing under strong interference conditions.

Overview
Key Features
Multi-Channel Anti-Interference Processing
The system can receive, amplify, down-convert, filter, and perform anti-interference processing on GPS L1 and GLONASS L1 frequency signals of 4 channels, ensuring high-precision positioning and timing even under strong interference.
Broadband Interference Resistance
It can suppress diverse interferences such as broadband, sweep frequency, and pulse, providing reliable performance in challenging environments and able to simultaneously resist 3 interference sources from different directions.
Compact, Rugged, and Lightweight Design
Weighing less than 360g, the system is designed to be compact and rugged, ensuring reliable performance in harsh conditions such as extreme temperatures ranging from -45°C to +80°C (operating: -40°C to +75°C).
Low Power Consumption and High Efficiency
With a power consumption of less than 9.5W, the system is energy-efficient, suitable for various applications with limited power resources, while maintaining high positioning accuracy of ≤ 10m and speed measurement accuracy of <0.2 m/s.
