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. 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. 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. 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. 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. 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.
