The WL125 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 an
anti-jamming solution for multi-system integration. 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, commercial vehicles), UAVs, and
ships. It can be compatible with the power supply systems of
different devices to meet power supply requirements 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 (≤460g), suitable for
lightweight applications sensitive to weight (such as small UAVs);
aluminum alloy material (≤600g) has better structural strength,
suitable for scenarios with higher strength requirements (such as
fixed monitoring equipment), and can be selected according to
actual needs. Will the anti-jamming capability be affected under multi-system
signal fusion?Answer: The system has been specially optimized for multi-system
signals. Even when processing multi-system signals simultaneously,
it can still maintain the capability to counter 3 wideband
interference sources, with an anti-single wideband SNR of
≥105dB@-130dBm, ensuring positioning accuracy under strong
interference. What is the advantage of the system's positioning accuracy with
multi-system support?Answer: Multi-system signal fusion increases the number of visible
satellites and positioning redundancy. Even in urban canyons and
weak signal areas, it can achieve ≤10m high-precision positioning
through multi-system collaboration, improving the stability and
reliability of positioning.
