High-Rate 64-Channel LiDAR

The RS7 uses a 64-channel LiDAR scanner to capture dense 3D geometry as the operator walks through the project area.

• Single Return: 576,000 points/sec
• Dual Return: 1,152,000 points/sec
• Laser Wavelength: 905 nm
• Laser Classification: Class 1 Eye Safe
• Maximum Range: 40 m at 10% reflectivity
• Field of View: 360° horizontal × 189° vertical

Its ultra-wide field of view makes it easy to scan walls, ceilings, floors, corners, and surrounding structures without the repeated setup and repositioning associated with traditional stationary laser scanners.

Deep INS + SLAM Fusion

The RS7 combines LiDAR SLAM technology with high-precision inertial navigation to maintain reliable positioning while moving through complex environments.

Its integrated 500 Hz IMU helps improve trajectory tracking through corridors, staircases, and repetitive indoor spaces where conventional SLAM systems may experience positioning drift.

This allows operators to scan large areas continuously while minimizing interruptions to reposition equipment.

Survey-Grade Accuracy

The RS7 is designed to deliver high-quality measurements for surveying, engineering, and building documentation.

• Horizontal Absolute Accuracy: <3 cm RMS
• Vertical Absolute Accuracy: <3 cm RMS
• Relative Accuracy: <1 cm
• Repeatability: <2 cm

Actual accuracy depends on environmental conditions, scanning procedures, GNSS availability, control points, and processing methods.

Integrated GNSS – RTK, PPK & SLAM Workflows

Unlike scanners that operate exclusively in a local coordinate system, the RS7 includes integrated GNSS to support georeferenced scanning projects.

Supported workflows include:

• RTK Scanning: Uses real-time GNSS corrections to help establish accurately positioned scanning trajectories.
• PPK Processing: Combines recorded GNSS observations with base-station data during post-processing.
• Pure SLAM: Captures 3D point clouds without GNSS, making it suitable for indoor and underground applications.
• Control Point Adjustment: Uses surveyed control points to improve trajectory alignment and transform point clouds into known coordinate systems.

These flexible positioning methods make the RS7 suitable for indoor mapping, outdoor surveying, construction documentation, and projects requiring established coordinate systems.

SmartGo Field Data Collection

The RS7 operates through CHCNAV SmartGo, an Android-based scanning and data acquisition application.

SmartGo provides:

• Scanner connection and device monitoring
• Real-time point cloud visualization
• Live scanning trajectory display
• Project creation and management
• RTK/CORS configuration
• Control-point collection
• Point cloud colorization settings
• Battery and storage monitoring
• Scan start and stop controls

The RS7 also supports one-click scanning through its smart handle, allowing operators to initiate and complete scans without continuously interacting with their phone.

SmartGo handles field data collection, while CoPre and other optional software packages handle post-processing and deliverable creation.

CHCNAV RS7 Software Packages – Choose the Right Processing Solution

The CHCNAV RS7 is available with multiple software configurations depending on your intended applications.

Whether you only need to capture 3D scans, generate professional point clouds, produce CAD drawings, or create realistic 3D models, you can select the software package that best fits your workflow.

Scanner Only – No Processing Software

Best For: Customers who already own compatible third-party point cloud processing software or have an established reality capture workflow.

Includes the CHCNAV RS7 hardware and SmartGo data collection application.

• Capture scans using the RS7
• Monitor point cloud collection in real time
• Record scanning trajectories and project data
• Transfer collected data for processing

Important: No CoPre or CoProcess desktop processing licenses are included. Customers must have an appropriate compatible processing solution to turn their collected data into usable deliverables.

CoPre Standard – Perpetual License

Best For: Surveyors, contractors, architects, and scanning professionals who primarily need processed 3D point clouds.

Includes CHCNAV CoPre Standard with a permanent software license.

CoPre is the primary processing software for the RS7. It transforms raw LiDAR scans, positioning data, and captured imagery into refined 3D point clouds that can be viewed, shared, or imported into other compatible applications.

Key capabilities include:

• SLAM trajectory processing and optimization
• RTK and PPK trajectory processing
• Control-point adjustment and georeferencing
• Point cloud generation and refinement
• Noise filtering and point cloud optimization
• Point cloud colorization using captured imagery
• Coordinate system assignment
• Export of processed point cloud data

What can you do with CoPre Standard?

For example, you can walk through a building with the RS7, capture the entire interior, process the scan in CoPre, and export a detailed 3D point cloud.

You can then use that point cloud for visualization, measurement, documentation, or additional work in compatible third-party software.

What's not included? CoPre Standard does not include the dedicated CoProcess CAD drafting tools or the optional SLAM Mesh Modeling and 3DGS Modeling licenses.

Survey & CAD – CoPre + CoProcess Standard – Perpetual Licenses

Best For: Land surveyors, engineering firms, architects, construction professionals, and contractors who need CAD drawings and measurements directly from scanned point clouds.

Includes everything in CoPre Standard, plus CHCNAV CoProcess Standard, with permanent licenses for both applications.

While CoPre is responsible for converting your raw scans into usable 3D point clouds, CoProcess adds the tools needed to analyze those point clouds and convert them into professional CAD deliverables.

Additional capabilities include:

• Advanced point cloud visualization and management
• Point cloud measurement and analysis
• Distance, area, angle, and elevation measurements
• Point cloud slicing and cross-section viewing
• Vector linework and feature extraction
• 2D floor plan creation
• Building elevation and section drawings
• CAD drafting and annotation tools
• DWG and DXF CAD deliverable generation

What can you do with Survey & CAD that CoPre Standard cannot?

For example, after scanning a commercial building, CoPre generates the 3D point cloud. With CoProcess Standard, you can use that point cloud to trace walls, create detailed floor plans, extract building elevations, and prepare CAD drawings for renovation or construction planning.

Instead of simply delivering a point cloud to your customer, you can produce usable drawings and measured documentation from the scan.

This is our recommended package for most surveying, construction, and architectural applications.
