The WL168 Four-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, Galileo, and GLONASS_L1
(optional frequency points: GLONASS_L1/BDS_B3) in 4 channels. 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. Which satellite navigation system signals does this system support?Answer: It supports L1 frequency band signals of four major
satellite navigation systems: Beidou (BDS_B1, optional BDS_B3), GPS
(L1), Galileo (E1), and GLONASS (L1, optional G1), providing a
multi-system integrated anti-jamming positioning solution. 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 can be compatible with the power supply systems of
different devices to meet power supply requirements in complex
environments and improve scene adaptability. What is the impact of the weight difference between aluminum alloy
and magnesium alloy materials on applications?Answer: Magnesium alloy material is lighter (≤700g), suitable for
lightweight applications sensitive to weight (such as small and
medium-sized UAVs); aluminum alloy material (≤900g) has better
structural strength, suitable for scenarios with higher strength
requirements (such as fixed monitoring stations, vehicle-mounted
equipment), and can be selected according to actual needs. Is the anti-jamming performance stable when processing multi-system
signals simultaneously?Answer: The system has been specially optimized for multi-system
signals. Even when processing multi-system signals simultaneously,
it can still stably counter 3 wideband interference sources, with
an anti-single wideband SNR of ≥110dB@-130dBm, ensuring that the
positioning accuracy is not affected under strong interference. How does multi-system integration improve positioning accuracy?Answer: Multi-system signal integration increases the number of
visible satellites and improves positioning redundancy. Even in
urban high-rise areas and signal-blocked areas, it can achieve ≤10m
high-precision positioning through multi-system collaboration,
significantly improving the stability and reliability of
positioning.
