Visual Positioning Technology

Leica GS18 I is a survey-grade GNSS RTK rover designed to expand what can be measured in the field. It enables professionals to capture images of the site and measure points directly from those images with survey-grade accuracy.

As a result, points can be measured either immediately in the field or later in the office. This approach reduces the need to physically reach each point and allows greater flexibility during data collection. For the GS18 I, the “I” represents imaging.

Visual Positioning is created through the fusion of GNSS, IMU, and camera sensors. Together, these technologies allow users to measure what they see. In addition, Leica GS18 I includes all the functionality of the GS18 T. Users can map points using either a tilted or levelled pole, depending on site conditions.

• Measure points more efficiently in areas with an obstructed view of the sky.
• Capture points that were previously difficult to reach with a GNSS rover.
• Gain greater flexibility and control without the need for additional time-consuming equipment.
• Map hundreds of points with survey-grade accuracy within minutes.
• Capture the scene quickly and decide later what should be measured, even if the scene changes or is no longer accessible.
• Select points directly on an image to measure them in the field or in the office.
• Work quickly and thoroughly to ensure every detail is captured.

ENGAGING SOFTWARE

Leica Captivate field software is designed to work seamlessly with the GS18 I, providing an intuitive and efficient field experience. With easy-to-use applications, measured and design data can be viewed and utilised clearly in both 2D and 3D environments. Captivate supports multiple industries and applications and allows users to switch between workflows with simple interaction, whether working with GNSS, total stations, or a combined setup.

INTERNAL MEMORY

All GS18 models provide flexible data logging options, allowing users to store raw data either on an SD card or directly within the internal memory, depending on project requirements and workflows.

IMPROVED PERFORMANCE

Multipath reduction and interference mitigation options in Captivate boost GNSS signal tracking quality under harsh environments, which improves RTK availability and accuracy. Also, an interference toolkit will enable filtering to remove in- and out-of-band distortions for even more robust GNSS signal tracking.

TILT COMPENSATION

GS18 I tilt compensation is based on sensor fusion between GNSS and IMU, making it immune to magnetic interference and ready to use immediately without calibration. This technology allows surveyors to measure points using either a levelled or tilted pole while automatically storing tilt values for each measurement. This ensures confidence and reliability in every recorded point.

4G LTE & EXCELLENT MEASUREMENT QUALITY

Multi-frequency GNSS signal tracking is standard across all Leica Geosystems GS sensors. Combined with a high-quality GNSS antenna element and a position update rate of 20 Hz, GS18 I delivers consistent and reliable measurement quality in demanding conditions.

ACTIVE CUSTOMER CARE

Active Customer Care (ACC) connects users to a global network of experienced professionals who are available to provide guidance and support when needed. With a Customer Care Package (CCP), operating costs can be controlled while ensuring coverage and peace of mind anytime and anywhere.
