The WL380 Six-Frequency Eight-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 multi-channels including Beidou BDS_B1,
BDS_B2, GPS_L1, GPS_L2, GPS_L5, GLONASS_L1, GLONASS_L2, GALILEO_L1,
GALILEO_E5A, QZSS_L1, QZSS_L2, QZSS_L5, IRNSS_L5, and IRNSS_S. It
operates at a power voltage of +28V to +32V and consists of three
main components: antenna array, RF component, and anti-jamming processing component. It enables efficient anti-jamming for multi-system and
multi-frequency signals, providing a guarantee for high-precision
positioning in complex scenarios. Which satellite navigation systems and frequency points does this
system support?Answer: It supports multiple systems and frequency points including
Beidou (BDS_B1, BDS_B2), GPS (L1, L2, L5), GLONASS (L1, L2),
GALILEO (L1, E5A), QZSS (L1, L2, L5), and IRNSS (L5, S). It is one
of the anti-jamming solutions with the most supported systems and
frequency points currently. Which scenarios is the +28V to +32V voltage range suitable for?Answer: It is suitable for industrial-grade and military-grade
equipment such as special vehicles, ships, and large monitoring
platforms, matching their high-voltage power supply systems to meet
the power stability requirements in complex scenarios. How does it perform in extreme scenarios when countering 7
interference sources simultaneously?Answer: It can cope with ultra-dense electromagnetic interference
environments (such as multi-base station clusters, electronic
countermeasure areas). Even with 7 interference sources from
different directions, it can still ensure the effectiveness of
navigation signals and maintain high-precision positioning of ≤10m. What are the installation requirements for dimensions and weight?Answer: The dimensions of (370±1)mm×(370±1)mm×(220±1)mm and weight
of ≤18kg are suitable for fixed installation scenarios (such as
ground monitoring stations, ship-borne equipment). When installing,
the spatial layout and load-bearing capacity need to be considered. How does multi-system and multi-frequency fusion improve
positioning accuracy?Answer: Multi-system and multi-frequency fusion greatly increases
the number of visible satellites and positioning redundancy. It not
only maintains high precision (≤10m) under strong interference but
also improves the continuity and reliability of positioning in weak
signal areas (such as remote areas, indoor edges).
