The WL181 Dual-Frequency Seven-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 GLO_G1 in
7 channels. It operates stably at a power voltage of +18V to +32V
and consists of four main components: antenna array, RF component, anti-jamming processing component, and
receiver. This system can counter six wideband interference sources and
provide high-precision positioning and precise timing services under strong interference conditions. Its RF output
supports external receivers. Which satellite navigation system signals does this system support?Answer: It supports signals from four major satellite navigation
systems: Beidou (BDS_B1), GPS (L1), Galileo (E1), and GLONASS (G1),
enabling multi-system integrated anti-jamming positioning. Which scenarios is the +18V to +32V voltage range suitable for?Answer: It is suitable for industrial-grade equipment such as
special vehicles, large UAVs, and ships, compatible with their
power supply systems to meet the power stability requirements in
complex scenarios. What is the practical value of being able to counter 6 interference
sources simultaneously?Answer: It can cope with ultra-complex electromagnetic interference
environments (such as dense urban areas, multi-base
station/electronic equipment interference areas), ensure the
continuity of navigation signals, and ensure that the positioning
accuracy does not degrade under strong interference. How do dimensions and weight affect installation?Answer: The dimensions of ≤Φ250mm×61.2mm and weight of ≤3kg can be
adapted to vehicle-mounted, ship-mounted, or fixed installation
scenarios, and are relatively friendly to installation space and
load-bearing requirements. How does multi-system fusion improve anti-jamming and positioning
accuracy?Answer: Multi-system signal fusion increases the number of visible
satellites and positioning redundancy, which not only enhances the
anti-jamming capability (can counter 6 interference sources
simultaneously) but also maintains high-precision positioning of
≤10m in signal-blocked areas (such as urban canyons), improving
positioning stability and reliability.
