Integrates an 8-channel dual-band CRPA antenna array, adaptive anti-jamming processing, and a GNSS receiver within a single rugged enclosure.
Compact Ø240mm × 42mm housing with a total weight of ≤1,550 g, combining dual-band anti-jamming and GNSS positioning in a highly integrated system.
Supports GPS L1/L5, Galileo E1, and BeiDou B1, providing multi-constellation GNSS reception and dual-frequency positioning capability.
Suppresses up to 7 simultaneous jammers per frequency band, with a specified anti-jamming capability of up to 100 dB J/S. Supports adaptive mitigation of broadband, narrowband, pulsed, sweep-frequency, and chirp interference.
The AJS-8L1/L5-240L is a lightweight, high-performance GNSS anti-jamming terminal that integrates an 8-channel dual-band (L1/L5) antenna array, an adaptive anti-jamming module, and an UBLOX receiver into a single rugged enclosure.
Supporting GPS L1/L5, GAL E1, and BDS B1, the unit provides active spatial defense against multi-source suppression interference. Its advanced adaptive filtering and optimized antenna geometry ensure exceptional signal integrity and continuous high-precision positioning in RF-contested environments.
The 16-element CRPA array dynamically identifies jamming signals and creates “Deep Nulls” in their direction. Even with multiple or mirrored jammers, the antenna maintains a high-gain beam toward GNSS satellites, ensuring uninterrupted PNT (Position, Navigation, and Timing) in contested environments.
