WL839 Dual Frequency Four Channel Global Navigation Satellite System (GNSS) Anti Interference System

1. Product Introduction

The WL839 Dual-Frequency Four-Channel Global Navigation Satellite System (GNSS) Anti-jamming System is designed to receive, amplify, down-convert, filter, and perform anti-jamming processing on frequency signals of Beidou BDS_B1, GPS_L1, and GPS_L2 in 4 channels (GPS_L2 frequency can be replaced with BDS_B2 or other frequency points). It operates stably at a power voltage of +12V to +32V and consists of four main components: antenna array, RF component, anti-jamming processing component, and receiver. This system can counter three wideband interference sources and provide high-precision positioning and precise timing services under strong interference conditions.

3. FAQ (Frequently Asked Questions)

  1. Can the supported frequency points of the system be customized?Answer: Yes, the GPS_L2 frequency can be replaced with BDS_B2 or other frequency points to meet the frequency band requirements in different scenarios. For specific customization solutions, please consult the manufacturer.
  2. Which scenarios is the +12V to +32V wide voltage power supply suitable for?Answer: It is suitable for industrial-grade equipment such as vehicles (e.g., special vehicles, engineering vehicles), UAVs, and ships. It is compatible with the power supply systems of different devices, improving adaptability in complex scenarios.
  3. What is the impact of the weight difference between aluminum alloy and magnesium alloy materials on applications?Answer: Magnesium alloy material is lighter (≤850g), suitable for lightweight applications sensitive to weight (such as small and medium-sized UAVs); aluminum alloy material (≤1050g) has better structural strength, suitable for scenarios with higher strength requirements (such as fixed monitoring equipment, vehicle-mounted terminals), and can be selected according to actual needs.
  4. What is the advantage of the dual-frequency design (e.g., B1/L1, B2/L2)?Answer: The dual-frequency design can utilize the complementarity of signals in different frequency bands to improve positioning accuracy and stability in scenarios such as signal occlusion and multipath interference. At the same time, it enhances anti-jamming capability and ensures positioning reliability in strong interference environments.
  5. How to maintain positioning accuracy ≤10m under strong interference?Answer: Through dual-frequency signal fusion, anti-jamming algorithm optimization, and hardware design, the system can still stably achieve a positioning accuracy of ≤10m even when countering 3 wideband interference sources, meeting the requirements of high-precision applications.
