Frequently asked questions

What can the AlphaUni 20 be used for?

The AlphaUni 20 is a premium-grade, multi-platform LiDAR system that balances high-end performance with an economical entry point. It integrates CHCNAV’s cutting-edge technology into a versatile frame, allowing you to achieve exceptional data density and accuracy without the typical "premium-class" price tag.

How does AU20 mobile mapping system ensure data accuracy?

At the core of the AU20 is a high-precision Inertial Navigation System (INS) coupled with a Global Navigation Satellite System (GNSS). The system uses a proprietary navigation algorithm to fuse data from these sensors, maintaining a stable trajectory even when GNSS signals are obstructed by "urban canyons" or dense tree cover.

Can AU20 mobile mapping systems be used for large-scale projects?

Yes, the AlphaUni 20 is specifically engineered for high-efficiency, large-scale mapping. It combines a long-range capability of up to 1450 metres with an ultra-fast scanning rate of 2 million points per second.

This allows you to cover vast areas—such as extensive highway corridors or large forestry tracts—in significantly less time than standard sensors. Its multi-platform versatility also means you can switch from vehicle-based road surveys to airborne mapping in minutes, providing the operational flexibility required for complex, wide-area infrastructure projects.

What platforms are compatible with the AlphaUni 20?

The AlphaUni 20 is a truly multi-platform system, designed for seamless transition between air, land, and marine environments. Thanks to its lightweight 2.82 kg design and universal Alphaport connection, it is compatible with:

  • Aerial Platforms: Unmanned Aerial Vehicles (UAVs/drones), as well as crewed aircraft such as helicopters and light aeroplanes.
  • Land Vehicles: Easily mounted to cars, trucks, or trains for high-speed highway and railway inspections.
  • Marine Vessels: Suitable for mounting on boats or Unmanned Surface Vehicles (USVs) for coastal and riverbank mapping.
What's the maximum measurement range of the AU20?

The AU20 can measure up to 1450 metres.
