Overview

About the U1

The U1 AR visual RTK receiver features a compact, lightweight, and portable design. It is equipped with a high-performance, high-precision satellite positioning OEM board that supports full-constellation, multi-frequency GNSS signal processing and fully supports the BeiDou navigation satellite system. Featuring AR imaging capabilities, it enables dual AR real-scene stakeout on both the receiver and the data controller. Combined with the receiver's calibration-free IMU tilt compensation, field efficiency is significantly improved.

U1 AR Visual RTK Receiver: Compact Form, Visual Power

The U1 AR visual RTK receiver features a compact, lightweight, and highly portable design. Equipped with a high-performance, high-precision GNSS positioning OEM board, it supports all-constellation, multi-frequency GNSS signal tracking with comprehensive support for the BeiDou navigation satellite system. Featuring an AR camera system, it enables dual AR real-scene stakeout on both the receiver and data controller. Combined with calibration-free IMU tilt compensation, it significantly boosts field productivity.

Equipped with a high-performance, high-precision GNSS SoC chip to ensure premium signal tracking quality, it tracks all constellations and frequencies across BeiDou, GPS, GLONASS, Galileo, and QZSS, rapidly acquiring, locking, and processing GNSS satellite signals.

AR Enhanced • Multiplied Efficiency

Enhanced with AR, stakeout points are marked directly in the real-world video feed for fast, one-step point location. Dual AR visualization on both data controller and receiver provides intelligent guidance throughout the entire stakeout workflow.

Lightweight & Portable • Powerful Performance

As an IMU RTK receiver, the U1 AR delivers robust performance in an ultra-compact form factor. Measuring just 98 mm × H45.5 mm and weighing only 380 g, it provides exceptional portability for field operations.

Calibration-Free IMU • Effortless Tilt Stakeout

Boosts field efficiency by 50%, delivering pole-tip positioning accuracy of ≤3 cm at 30° tilt and ≤5 cm at 60° tilt.
