CHC Navigation builds GNSS, LiDAR and UAV mapping hardware, CoMeta photogrammetry and 3DGS software, and CoViewer, a free desktop 3DGS viewer.

Location

Shanghai, Cn

Platform

Desktop apps (Windows 10 and 11, 64 bit), CoMeta for processing and CoViewer for viewing, plus CoCloud, a cloud native processing and viewing platform

GPU

None published. CoMeta is 64 bit Windows desktop software, and native 3DGS reconstruction at the scale CHCNAV describes, more than 100,000 images in one project, implies a discrete GPU. Distributed processing spreads the load across 15 or more cluster nodes. CoViewer lists only 64 bit Windows 10 or 11 and renders 3DGS locally on the machine's own GPU. CoCloud processes in the cloud or on a private deployment

Pricing

CoViewer is free. CoMeta pricing is not published and is quoted through CHCNAV sales and its dealer network. CoCloud offers a free plan and Basic and Advanced tiers, priced by configuration on inquiry

City scale UAV photogrammetry with native 3DGS output, and free desktop review of 3DGS deliverables

Updated

July 2026

CHC Navigation, which trades as CHCNAV, is a Shanghai company building mapping, navigation and positioning hardware and software. Its catalogue covers GNSS receivers, airborne and mobile LiDAR systems such as the AlphaAir 15 and AlphaAir 6, the X500 multirotor drone, the C30 aerial oblique camera, and machine control systems for excavators, dozers, graders and compactors. It sells worldwide through a dealer network alongside direct sales.

CoMeta is the product that carries gaussian splatting. CHCNAV launched it on September 10 2026 as professional desktop software combining photogrammetry and native 3D Gaussian Splatting in one processing environment, turning UAV and camera imagery with positioning and orientation data into georeferenced orthomosaics, digital surface models, textured meshes and 3DGS models. A single aerial triangulation result feeds every output type, so the measurement oriented deliverables and the photorealistic scene come from the same solve rather than from two separate runs.

Scale is the claim CHCNAV leads with. One CoMeta project can process more than 100,000 images, and distributed cluster processing spreads work across 15 or more computing nodes. CHCNAV says automated batch processing and dual engine computation completed end to end aerial triangulation, orthomosaic generation and mesh reconstruction roughly two to three times faster than the mainstream software configurations it tested, and that the 3DGS workflow cut manual retouching time by more than 70 percent on water surfaces, glass facades, vegetation and thin structures against the conventional mesh refinement workflow it compared with. Neither benchmark names the competing software or the hardware it ran on.

Format support is where CoMeta is unusual. Orthomosaics and digital surface models write to .tif, meshes to .osgb, .3dtiles and .obj, and 3DGS models to .ply and .3dtiles. Writing gaussian splats into 3D Tiles rather than only into PLY puts the splat output straight into the streaming tileset format that GIS and digital twin viewers already consume. CoMeta also carries a coordinate reference system library of more than 9,910 entries, and a calibration database of more than 400 camera profiles covering systems from DJI, Sony, Feima, RIY, Saier and others, so existing datasets from existing field equipment process without a proprietary acquisition platform.

CoMeta runs on 64 bit Microsoft Windows 10 or 11 and ships interface languages in English, Chinese and Russian. CHCNAV publishes no price and no system requirement for the software, and routes buyers through an inquiry form and its dealer network.

CoViewer is the free viewing side of the same catalogue. CHCNAV posted version 1.0.0, a build dated September 15 2026, to its support portal on October 8 2026 with sample data, and announced it the following day. The lightweight Windows desktop viewer opens PLY, 3D Tiles and CHCNAV's own HSC 3DGS models, and adds orbit flythrough, elevation clipping that strips upper levels away to expose floor layouts and interiors, and solid color or panoramic image backgrounds for presentation. Signing in to CoCloud, CHCNAV's cloud processing platform, from inside CoViewer downloads a cloud generated 3DGS project for offline review. CHCNAV tunes the viewer for handheld scanning data and complex indoor environments, lists it alongside its RS10 and RS7 handheld LiDAR scanners, and ships it for 64 bit Windows 10 or 11 in English and Chinese.

CoCloud is the cloud side of the catalogue. Users upload field data to the cloud native platform, which processes, stores and manages data from CHCNAV's AA9, AA10 and RS10 series and other devices and generates point clouds, orthophotos, 3D models and 3D Gaussian splatting results, then displays point clouds, meshes, panoramas and 3DGS online with measurement, annotation, sharing, APIs and private deployment. CoCloud is offered as a free plan and Basic and Advanced tiers, with pricing set by configuration and quoted through CHCNAV's inquiry page.

Frequently Asked Questions

What is CHCNAV CoViewer?

CHCNAV CoViewer is a free, lightweight Windows desktop viewer for 3D Gaussian Splatting models. Version 1.0.0 opens PLY, 3D Tiles and CHCNAV HSC 3DGS files, and adds orbit flythrough, elevation clipping and custom solid color or panoramic backgrounds for presenting scans.

Is CHCNAV CoViewer free?

CHCNAV CoViewer is a free download from the CHCNAV support portal, where version 1.0.0 was posted with sample data on October 8 2026. CHCNAV CoMeta, the company's processing software, is not free and is quoted through CHCNAV sales and its dealer network.

How does CHCNAV CoMeta create Gaussian splats?

CHCNAV CoMeta builds 3D Gaussian Splatting models from the same aerial triangulation that produces its orthomosaics, digital surface models and meshes, and exports the splats to PLY and 3D Tiles. One CoMeta project can hold more than 100,000 images, and processing can be distributed across 15 or more cluster nodes.

Can CHCNAV CoViewer open CoCloud projects offline?

CHCNAV CoViewer connects to CoCloud, CHCNAV's cloud processing platform. A user signs in to CoCloud through CoViewer, selects a 3DGS project, downloads it and opens it locally, so review and presentation continue without a connection.

What are the system requirements for CHCNAV CoMeta and CoViewer?

CHCNAV CoMeta and CoViewer both run on 64 bit Microsoft Windows 10 or 11, and CHCNAV publishes no GPU requirement for either application. CoMeta ships in English, Chinese and Russian, and CoViewer in English and Chinese.

What is CHCNAV CoCloud?

CHCNAV CoCloud is a cloud native processing and visualization platform that turns uploaded field data into point clouds, orthophotos, 3D models and 3D Gaussian splatting results and displays them online. CoCloud has a free plan and Basic and Advanced tiers, priced by configuration on inquiry.
