UNIQUENAV U20 is a portable multi-functional GNSS. It has a built-in high-precision positioning module that supports tracking satellite signals from all systems and frequency bands. It is equipped with 4G full network access, WIFI and built-in data transmission radio. The high-precision IMU integrates AR and Laser to achieve tilt measurement, Laser measurement and AR real-Time Stakeout, making the measurement work more convenient and efficient.
Linux Smart System
Linux+ARM Cortex-A7 intelligent system platform offers efficient computation and unlimited product functionality expansion.
Full System GNSS Reception
The receiver integrates a high-precision positioning module, utilizing 1408 channels to support a comprehensive range of signals including BDS (B1I/B2I/B3I/B1C/B2a/B2b), GPS (L1/L2/L5), GLONASS (L1/L2/L3), Galileo (E1/E5a/E5b/E6), QZSS (L1/L2/L5),SBAS and NavIC.
Tilt Measurement
Built-in intelligent high-precision inertial navigation module for real-time tilt compensation, eliminating "fly points" in RTK measurement
Laser Measurement
Equipped with a high-precision millimeter-level laser ranging module, combined with high-precision inertial navigation for accurate laser targeting in complex environments.
AR Real-Time Stakeout
Utilizes a professional ultra-wide-angle camera to provide high-definition real-time plotting functionality, making stakeout tasks more accurate and convenient.
4G Full NetCom
The 4G NetCom solution based on the Linux platform fully supports 2/3/4G networks, offering better compatibility, stronger signals, and more stable connections
Long Endurance
Built-in large capacity lithium battery, to ensure normal operation, continuous working time more than 16 hours (network data link mode).
Reliable
Industrial design, strong magnesium alloy shell, meet the IP68 design requirements, safe and reliable
