Overview

About the U1

The U1 is an engineering-grade IMU RTK receiver equipped with a high-performance, high-precision satellite positioning OEM board. It supports full-constellation, full-frequency GNSS signal processing with comprehensive support for the BeiDou satellite navigation system. Featuring narrowband anti-interference technology and automatic ionospheric optimization, it satisfies surveying demands in complex environments. Supporting IMU tilt compensation technology, it enables instant measurement without leveling for efficient on-the-go stakeout. Its compact and lightweight body is easy to carry, significantly boosting field productivity.

Specifications

The U1 is an engineering-grade IMU RTK receiver equipped with a high-performance, high-precision GNSS OEM board. It supports full-constellation, full-frequency GNSS signal tracking with comprehensive support for the BeiDou navigation satellite system. Featuring narrowband anti-jamming technology and automatic ionospheric mitigation, it meets the survey requirements of challenging environments. Supporting IMU tilt compensation, it allows instant measurement without leveling, enabling seamless walking stakeout. Compact and lightweight, it significantly boosts field productivity.

Full-Constellation, Full-Frequency • Fast Signal Lock

Equipped with a high-performance, high-precision GNSS SoC chip to ensure signal reception quality, it tracks all constellations and frequencies across BeiDou, GPS, GLONASS, Galileo, and QZSS, enabling rapid satellite acquisition, tracking, and processing.

Lightweight & Portable • Powerful Performance

As an IMU RTK receiver, the U1 delivers powerful performance in a compact body, measuring only Φ98 mm × H45.5 mm and weighing just 380 g, making field operations light and convenient.

Calibration-Free IMU • Effortless Tilt Survey

Increases field productivity by 50%, with pole-tip positioning accuracy of ≤3 cm at 30° tilt and ≤5 cm at 60° tilt.

Stable Signal

Supports narrowband anti-jamming technology and automatic ionospheric mitigation, actively detecting and effectively suppressing internal and external interference signals to meet survey demands in complex environments. One-Click Fixed: One-click configuration for nationwide CORS differential services, achieving fixed solutions upon startup and supporting direct measurement in CGCS2000 and other coordinate systems. Worry-Free Battery Life: Built-in smart lithium battery supports up to 12 hours of daily operation; the Type-C port supports PD fast charging and power bank supply for uninterrupted field work. Dual Data Backup: Survey data can be simultaneously backed up on both the data controller and receiver for double data security. 3-Year Free Cellular Data: Ready to measure out of the box with 3 years of free data. Industrial-Grade Protection: IP67 industrial protection prevents dust ingress and component damage, providing complete protection even against prolonged water immersion.
