Geoscan 401 Lidar
Geoscan 401 Lidar
The unmanned aerial system provides prompt digital terrain models development — even for forested areas
Geoscan 401 Lidar system with an AGM-MS laser scanner and a Sony A6000 camera
System description
The Geoscan 401 Lidar system is designed for laser scanning and upcoming development of digital terrain models or models of particular objects. Unmanned aerial vehicle (UAV) can take off from a 5 m radius site, operate within confined space and accurately bend round terrain. It carries an AGM-MS laser scanner with inbuilt GNSS-receiver and an option of connecting up the Sony A6000 camera. Such combination gives an opportunity of simultaneous carrying out the aerial photographic surveying and laser scanning. In order to increase accuracy and detail of 3D objects, dense point clouds created on the basis of both survey method can be compounded.
Advantages
High productivity
System is able to be airborne for 40 minutes and develop a speed of 50 km\h. UAV performs aerial photo survey of 1,7 km2. per one flight.
Efficiency
Lidar effectively generates dense point cloud even within forestry area and guarantees accurate terrain reconstruction. Simultaneous work of photo camera and lidar provide creating highly detailed 3D models.
Convenient operating
Specialized well-adjusted autopilot developed by Geoscan arranges customer’s tasks fulfillment requiring no alignment or refining. Software makes operation easy and safe.
Reliability
Manoeuvring system follows any complicated route providing accurate bending round the terrain and steers the course even at wind speed 12 m/sec in fully-automatic mode.
Utility
Vertical launch and landing make drone suitable for using in a tight city space or in a thick forest. Smart battery covered with special shell guarantees fail-safe operating at temperature range from – 40 to +40 °С (arctic option).
Key application fields
- Engineering and geodetic surveying
- infrastructure facilities modeling
- conditioning of roads and railways
- Data generation for geoinformation and computer-aided engineering systems of various purpose
The Geoscan 401 Lidar system effectively carries out the aerial survey of vertical surfaces (building faces), forests, areas with large-statured trees or high level difference (cast mines, mountainous areas). Laser scanning in accordance with designated route is performed automatically. Survey data can be used for developing geotagged orthophotomaps, 3D and digital models of terrain.
Depending on client’s goals complex can be equipped with AGM-MS1 or AGM-MS3 laser scanner.

Geoscan Planner. Software for flight assignment planning
Plan flights in a couple of clicks and use various flight modes. Just select flight area or upload it from the file. The program plans the flight assignment automatically, sends it to UAV during pre-launch preparation and monitors flight accuracy after the start.
Flight in automatic mode requires no permanent connection with laptop or direct involvement of operator. It guarantees task performance even if connection is lost and removes the human factor.
