Overview

The Sokkia SR-S2 Handheld 3D Scanner is a compact SLAM-based reality-capture solution designed for fast, flexible, one-person data collection. Designed for construction surveying, geospatial mapping, engineering, utilities, facilities, infrastructure, stockpile measurement, and underground documentation, the SR-S2 allows crews to scan while walking through complex project environments.

Using advanced multi-sensor fusion, the SR-S2 combines MLF-SLAM, visual SLAM, RTK-SLAM, PPK-SLAM, LiDAR, IMU, visual data, and GNSS positioning enhanced with RTK corrections. This helps deliver stable, repeatable positioning across outdoor, indoor, and GNSS-challenged environments where traditional GNSS workflows may be difficult.

The SR-S2 is ideal for teams that need a portable handheld SLAM scanner to capture real site conditions quickly, create accurate 3D point clouds, verify project conditions, calculate quantities, and improve field-to-office documentation.

Built for Fast Reality Capture

The Sokkia SR-S2 is designed to help professionals capture more field data with less setup time. Instead of occupying multiple tripod scan positions, users can walk the site while collecting point cloud and imagery data in a continuous workflow.

Ideal applications include:

• Construction documentation
• Progress monitoring
• Topographic surveying
• Utility mapping
• Facilities documentation
• Infrastructure inspection
• Volume calculations
• Stockpile measurement
• Underground data capture
• Tunnel and mining documentation
• Indoor and outdoor mapping
• As-built surveys

This mobile scanning workflow helps reduce return visits, improve project documentation, and give crews more confidence that the required site data has been captured.

Strong Performance in GNSS-Challenged Areas

The SR-S2 is built for complex environments where GNSS signals may be weak, blocked, or unavailable. By combining LiDAR-based SLAM, visual SLAM, inertial measurements, and GNSS positioning with RTK corrections, the scanner helps maintain stable positioning across changing site conditions.

This makes it useful for interiors, tunnels, covered areas, dense construction sites, utility corridors, urban canyons, wooded areas, and other challenging environments where standard GNSS-only collection may not be practical.

Survey-Grade Accuracy in a Lightweight Scanner

The Sokkia SR-S2 delivers professional measurement performance in a compact handheld design. With absolute accuracy under 3 cm and relative accuracy under 2 cm, it provides dependable data for many field documentation, mapping, inspection, and quantity workflows.

The integrated 1408-channel RTK GNSS receiver supports major satellite systems and NTRIP corrections, helping improve georeferenced scan workflows when GNSS conditions allow. The system also supports PPK-SLAM and RTK-SLAM workflows for added flexibility.

Real-Time Point Cloud Preview

The SR-S2 supports real-time point cloud preview, helping crews verify coverage while still on site. This is especially useful when scanning complex spaces, structures, tunnels, utilities, or active jobsites where missed coverage can cause costly rework.

Post-processing produces accurate 3D point clouds and orthophotos, supporting workflows from quick field checks to complete 3D site documentation.

Optional Topnet Live Configuration

• 1 × Topnet Live Subscription, 1-Year

Topnet Live is included only when selecting the SR-S2 configuration with Topnet. This subscription provides access to GNSS correction services for RTK-supported workflows and helps improve positioning confidence when collecting georeferenced scan data.

What Is Topnet Live?

Topnet Live is Topcon’s real-time GNSS correction service used to improve positioning accuracy for compatible GNSS receivers in surveying, construction, GIS, mapping, agriculture, machine control, and related applications. Instead of setting up your own local base station, a compatible rover or RTK-enabled system can receive correction data through Topnet Live to achieve more accurate field positioning.

For the Sokkia SR-S2, Topnet Live is useful when you want stronger georeferenced scan data in supported coverage areas. It can help connect the scanner’s RTK workflow to correction services, improving positioning confidence during reality capture and site documentation.

Topnet Live includes different correction service options, including Realpoint RTK, Skybridge RTK backup, and Starpoint Pro PPP. Realpoint provides network RTK corrections via NTRIP, with horizontal accuracy listed at 2 cm, while Starpoint Pro provides global PPP corrections with horizontal accuracy of 3 cm and vertical accuracy of 5 cm.

In simple terms, Topnet Live helps the SR-S2 locate itself more accurately, especially when collecting georeferenced scan data for mapping, construction documentation, utilities, stockpiles, facilities, infrastructure, and site records.
