Product Description

Walk the site. Leave with a georeferenced point cloud.

The CHCNAV RS7 is a handheld LiDAR SLAM scanner with RTK GNSS built in, and it’s the tool for the jobs where a rover can’t hold a fix and a tripod scanner would take all day: topo under canopy, stockpiles, building as-builts, and anything underground. You walk the site at a normal pace. The RS7 tracks its own position, builds a colorized point cloud as you go, and shows it live on your phone so you can see gaps before you leave.

Put it on your coordinates three ways: RTK corrections through your phone, control points checked and adjusted in CoPre, or a local system when the job doesn’t need more. Under the hood: up to 1.15 million points per second, a 360° × 189° field of view, a 0.5°/h IMU that holds the trajectory where SLAM usually drifts, dual HD cameras, and 3D Gaussian Splatting output. 1.2 kg in the hand.

Where it fits

SLAM (Simultaneous Localization and Mapping) means the scanner solves its own position continuously from the geometry around it. No setups, no targets required, no GNSS required. Instead of occupying stations and registering scans afterward, you walk one continuous path and the registration happens as you go. Add the RS7’s onboard RTK and the cloud lands on your project coordinates without a separate tie-in.

That makes it the instrument for the work that falls between a GNSS rover and a terrestrial scanner:

• Topo on sites where the canopy or the buildings kill your fix
• Stockpile and pit volumes without walking a rover over every breakline
• As-builts and interiors at a walking pace instead of a dozen setups
• Tunnels, vaults, basements, and anything else with no sky

It is not a replacement for your rover or total station on boundary and control work. It’s the tool for everything else.

Three ways to put it on your coordinates

RTK. The RS7 has a multi-constellation GNSS receiver onboard (GPS L1/L2/L5, GLONASS, BeiDou, Galileo). Corrections come in over NTRIP through your phone’s data connection, using your existing network subscription. Absolute accuracy is under 3 cm RMS, horizontal and vertical, in open sky. Initialize outside and walk in; the SLAM trajectory carries your coordinates through the door.

Control points. Shoot or occupy control anywhere, inside or out, and check and adjust the cloud to it in CoPre. This is the workflow for tight tolerances, for sites with poor sky, and for anyone who wants check shots on the record.

Local coordinates. For interior-only work, skip georeferencing and work in a local system. Tie it in later if the job changes.

What the accuracy numbers mean

The datasheet gives three figures, and they answer different questions.

In practice: right for topo, as-builts, volumes, interiors, and underground mapping. Not for boundary or control-level precision; that stays with your rover and total station.

Why it holds up where SLAM drifts

SLAM on its own struggles where there’s little distinctive geometry: a long blank corridor, a stairwell, a tunnel, a warehouse aisle, repetitive floor plates. The RS7 fuses its SLAM engine with a high-grade inertial system, gyro bias instability better than 0.5°/h at a 500 Hz update rate, so the trajectory holds through those stretches instead of wandering. Fewer failed loops, fewer re-walks, cleaner data on exactly the jobs that break lighter units.

Full coverage in one pass

A 64-channel LiDAR at up to 1.15 million points per second in dual-return mode (576,000 single return), 40 m range at 10% reflectivity, and a 360° horizontal by 189° vertical field of view. Floors, walls, ceilings, the pile and the ground around it, all in the cloud from one walk. No tilting the unit for ceilings or re-walking corners.

Color, imagery, and 3D Gaussian Splatting

Dual 12 MP cameras (48 MP sensors, pixel-binned for low light) colorize the cloud and hold up in dim interiors and vaults. CHCNAV’s HPGS 2.0 engine turns the same capture into a 3D Gaussian Splatting model: a photorealistic, navigable scene a client can read at a glance, alongside the measurable cloud.

Field to deliverable

• SmartGo NEO (Android) runs the scanner over Wi-Fi: project setup, NTRIP connection, live point cloud, playback, and upload. Android phone or tablet required; there is no iOS version.
• CoPre, included with a perpetual license, does the office work: trajectory processing, control-point adjustment and refinement, point cloud generation, and 3D modeling, with colorized point clouds, mesh models, and 3DGS as outputs. Export to standard point cloud formats [FORMATS: LAS/LAZ, E57, etc.] for Carlson, Civil 3D, or whatever you draft in.
• CoProcess (optional) adds point cloud processing with built-in CAD tools for scan-to-CAD, sections, and terrain modeling.
• CoCloud (optional) gives you one-click upload from the field and automatic processing to point clouds, meshes, and 3DGS, with project management for a team.

What surveyors are running it on

Here’s what the surveyors we know with an RS7 are actually using it for.

Topo under canopy and on obstructed sites. Walk the site with RTK, let SLAM hold position where the sky closes in, and hit control on the way out. Surfaces and contours from the cloud instead of a rover fight.

Stockpiles and volumes. Walk around and, where safe, over the pile. Build the surface and run volumes in CoProcess or the package you already use. Repeat next month and compare.

As-builts and building interiors. Every floor, wall, ceiling, and stair in one pass, colorized. Floor plans, sections, elevations, and scan-to-BIM from the cloud.

Underground, tunnels, and utility vaults. No sky, no problem. Tie in at the portal or to control inside, and the IMU carries you through the featureless stretches.

FAQ

Does the RS7 have RTK? Yes, on every unit. The GNSS receiver is built in, and corrections come in over NTRIP through your phone’s data connection. Open-sky absolute accuracy is under 3 cm RMS.

Can I tie it to survey control? Yes. Shoot or occupy control points or targets, indoors or out, and check and adjust the cloud to them in CoPre. Most interior-only jobs run in local coordinates and skip this step.

How accurate is it? Under 1 cm relative, under 2 cm repeatability, under 3 cm RMS absolute with RTK. Field results depend on loop closure, walking speed, sky, and environment. Right for topo, as-builts, volumes, interiors, and underground; not for boundary or control.

What do I need to run it? An Android phone or tablet with SmartGo NEO, a network correction subscription if you want RTK, and a PC for CoPre. There is no iOS app.

Do I need CoCloud? No. CoPre is included and handles processing. CoCloud is optional for automated cloud processing and team project management.

How long does a battery last? About 150 minutes per handle under standard test conditions. The battery is built into the handle. [KIT: how many handles ship with it]

What does it cost? $9,945 for the standard kit. Financing available, trade-ins welcome, and we’ll quote CoProcess, CoCloud, extra batteries, and training as options.
