Overview

About the U3

Powered by AR imaging, real-scene AR stakeout delivers a 'what you see is what you measure' experience, significantly boosting stakeout efficiency. Full-constellation, multi-frequency GNSS tracking with a powerful RTK positioning engine delivers strong signals and fast fix. The onboard IMU tilt compensation module requires no dedicated initialization, ready to measure right out of the box. Integrated nationwide CORS high-precision differential service enables one-click fix and direct output of CGCS2000 coordinates.

Specifications

Enhanced with AR imagery and real-scene visual stakeout, what you see is what you measure, doubling stakeout efficiency. Full-constellation, full-frequency GNSS satellite tracking with a powerful RTK engine delivers robust signals and fast fix times. Onboard IMU tilt compensation module requires no calibration or initialization, ready to measure immediately upon power-on. Built-in nationwide high-precision CORS differential service enables one-click fix and direct output of CGCS2000 coordinates.

Built-in CORS Service

— One-click setup, instant fix upon startup. Built-in nationwide CORS differential service achieves a fixed solution right upon power-on, supporting direct surveying in various coordinate systems including CGCS2000.

AR Visual Imagery

— AR-powered, doubling efficiency. Dual AR cameras on both data controller and receiver provide intelligent visual guidance throughout the entire stakeout workflow, dramatically boosting RTK stakeout efficiency.

Calibration-Free IMU

— No calibration, naturally efficient. Upgraded calibration-free IMU tilt compensation requires no dedicated initialization—ready to use out of the box, measuring fast and accurately.

Full Constellation

— Strong signals, reliable precision. High-performance GNSS chip with full-constellation tracking, adaptive anti-jamming technology, and an all-new RTK engine for fast fixes and high accuracy.
