YellowScan, the lightest LiDAR for UAVs aided by the Ellipse-E miniature inertial navigation system.

YellowScan research and development team was searching for a high performance, light, and ITAR free inertial navigation system for motion compensation and data georeferencing.

Rueil-Malmaison, France, September 4th 2015 - SBG SYSTEMS joins YellowScan to present the lightest LiDAR in the world at the Intergeo trade show in Stuttgart. YellowScan is the lightest LiDAR in the world for fixed or rotary wings UAVs while being highly efficient and easy-to-use. YellowScan embeds an Ellipse-E, the miniature inertial navigation systems from SBG SYSTEMS which helps obtaining a clear and accurate point cloud.

The UAV market is continuously growing, especially for professional applications like 3D surveying. Developed for this application, YellowScan has been designed to be the lightest all-in-one LiDAR in the world. It can be easily mounted on rotor or fixed-wings UAVs. To finely adjust the YellowScan, the R&D team has been working closely with researcher and professionals of several industries such as Construction, Surveying, Mining, and the study of forest, rivers, etc. It results in a comprehensive, high performance, and easy-to-use LiDAR.


YellowScan is a ready-to-use LiDAR, which is operational at up to 75 meters. It delivers a highly dense point cloud accurate to 10/15 centimeter. This comprehensive solution includes a LiDAR with a ±50 degree angle that measures 40,000 points per second, an Ellipse-E inertial navigation system coupled with a centimeter-level RTK GPS, an on-board computer, and an integrated battery.

Once mounted on the drone, the user pushes the yellow button and YellowScan is ready to survey. LED lights give useful information on YellowScan state, for instance if the GPS is receiving RTK corrections or not. The user can launch the UAV and begins the survey. Once the task accomplished, a USB stick is used for downloading the data. An office software is also delivered to visualize the point cloud in a few clicks, before opening it in an industry specific software like Terrasolid, AutoCAD, ESRI, etc.


YellowScan research and development team was searching for a high performance, light, and ITAR free inertial navigation system for motion compensation and data georeferencing. They tested the Ellipse-E, the new miniature inertial navigation systems from SBG. Weighting only 12 grams as OEM version, it provides roll and pitch data accurate to 0.2 degree. The heading is accurate to 0.5° with only one antenna. Indeed, the heading computation relies on GPS and accelerometers data. This method is used when GPS positioning is widely available and punctuated by frequent accelerations like turns. The R&D team found the test results very satisfying, and a point cloud highly clean We are very satisfied with this little Ellipse-E, it perfectly matches our technical needs, and we even gained 5% on the total weight of the YellowScan to conclude Tristan Allouis, CTO at YellowScan.


Ellipse-E is an inertial navigation system. It has the particularity of being able to connect to any survey grade GPS receiver and to fuse in real-time GPS position with inertial information. Ellipse-E maintains a reliable position even if GPS masks occur. In this application, the Ellipse-E is coupled with AsterX-m OEM card from Septentrio. This receiver uses GPS and GLONASS constellations and works with all types of RTK reference stations.

YellowScan enters the UAV-based surveying market with an original and innovative approach. It is an integrated solution, highly powerful and extremely easy to use, which can be installed on the drone of your choice, with additional sensors if necessary.

YellowScan will be presented on booth # F8.014
The ELLIPSE-E will be presented on booth # G4.079
