Leica GS18 I: Advanced GNSS RTK Rover with Visual Positioning Technology

Introduction to the Leica GS18 I

The Leica GS18 I is a high-performance, survey-grade GNSS RTK rover designed to revolutionize modern surveying workflows. Equipped with cutting-edge Visual Positioning technology, this device enables professionals to capture images on-site and measure precise points directly from those images—either immediately in the field or later in the office.

This capability makes the GS18 I an ideal choice for surveyors seeking speed, accuracy, and flexibility in challenging environments.

Key Features of the Leica GS18 I

1. Visual Positioning Powered by Sensor Fusion

The GS18 I integrates three advanced technologies—GNSS, IMU, and an onboard camera—to create a seamless Visual Positioning system. This fusion allows surveyors to measure points with survey-grade accuracy directly from captured images.

How Visual Positioning Enhances Productivity

• Enables precise point measurement from images

• Works effectively in both field and office environments

• Reduces the need for direct physical access to difficult terrain

2. High-Speed Data Capture

The GS18 I is engineered for efficiency. Users can capture detailed site imagery and extract hundreds of measurement points in just minutes.

Benefits of Fast Image-Based Measurement

• No need to physically reach every target point

• Less time spent on-site

• Fewer return visits, even if site conditions later change

3. Unmatched Versatility in the Field

With powerful imaging and multi-sensor capabilities, the GS18 I removes traditional fieldwork limitations. If you can see it, you can measure it—without switching tools or navigating obstacles.

Versatility Advantages

• Easily measure points with limited sky visibility

• Access locations that were previously out of reach for GNSS rovers

• Reduce reliance on time-consuming supplemental equipment

• Capture entire scenes and decide later which details to measure

4. All the Functionality of the Leica GS18 T

In addition to Visual Positioning, the GS18 I includes all the core features of the Leica GS18 T, including the ability to measure with a tilted or leveled pole.

Enhanced Measurement Capabilities

• Survey-grade point collection with pole tilt freedom

• Reliable results in obstructed environments

• Image-based measurement with simple tap-to-measure functionality

Top Benefits of Using the Leica GS18 I

Hassle-Free Measurement Through Imaging

Captured images can be used to measure points later, even if the site changes or becomes inaccessible.

Improved Accuracy and Detail Capture

By combining GNSS precision with visual data, surveyors can ensure comprehensive project documentation.

Maximized Team Efficiency

The ability to measure points remotely frees up personnel and eliminates workflow bottlenecks.
