Overview

About the S3

The S3 AR is a full-featured visual stakeout RTK receiver equipped with a high-performance, high-precision positioning OEM board that tracks all constellations and frequencies with full support for the BeiDou satellite navigation system. Featuring narrowband anti-interference technology and automatic signal optimization, it delivers intuitive AR real-scene stakeout in a single step. Pre-installed with STONEX's 4th-generation IMU tilt compensation technology, the unit features significant optimizations in aesthetics and weight over its predecessor, markedly boosting field engineering stakeout efficiency.

Specifications

The S3 AR is a fully featured visual stakeout RTK receiver equipped with a high-performance, high-precision positioning OEM board for full-constellation, full-frequency signal tracking, fully supporting the BeiDou satellite navigation system. It supports narrowband anti-interference technology and automatic ionospheric optimization. Featuring real-scene stakeout in one step, it comes pre-installed with Stonex 4th-generation IMU tilt compensation technology. The physical design and weight have been significantly optimized compared to the previous generation, markedly improving field engineering stakeout efficiency.

Real-Scene Stakeout · In One Step

The fusion algorithm of GNSS, IMU, and vision significantly mitigates the impact of electromagnetic interference, ensuring accurate stakeout. Combining RTK with live imaging, stakeout points are marked directly on the image for rapid point finding in a single step. Dual AR imagery from both the data controller and receiver supports intelligent guidance throughout the entire stakeout process, doubling operational efficiency.

Powerful Performance · Compact and Lightweight

As a versatile visual stakeout IMU RTK receiver, the S3 AR features a compact design with robust performance. With dimensions of 120 mm × 71.5 mm and a weight of only 513 g, it offers lightweight convenience for field operations.

IMU Measurement · Worry-Free Tilt

Equipped with Stonex 4th-generation IMU tilt compensation technology, it is immune to magnetic interference and requires no bubble leveling. Measure upon leveling the pole or stake out on the go, boosting operational efficiency by 50%.

Core Technology · High Efficiency & Tracking

Satellite Tracking - High-performance, high-precision positioning OEM board guarantees signal reception quality with full-constellation, full-frequency signal tracking and full BeiDou support, locking onto satellite signals rapidly. Signal - Supports narrowband anti-interference technology and automatic ionospheric optimization, actively detecting and effectively suppressing internal and external interference signals to meet surveying requirements in complex environments with efficient fixed solutions. Battery Life - Built-in dual smart lithium batteries provide 16 hours of daily operation. The Type-C port supports PD fast charging to reduce charge time. Power bank charging is supported for worry-free battery life in low-power situations. AR - Dual AR imagery on both data controller and receiver provides intelligent guidance throughout the stakeout workflow, doubling efficiency. Protection - IP67 industrial-grade protection resists dust ingress and prevents component damage, providing comprehensive protection even during prolonged water immersion. Network - Built-in eSIM enables instant surveying upon power-up with 3 years of free data, allowing network RTK operation without inserting a physical SIM card.
