The TerraScan Mini is an autonomous survey drone designed to survey large areas of land without human piloting.

The TerraScan Mini is an autonomous survey drone and companion app designed to quickly fly over an area of land and take photographs that will be stitched together into one large image.
The user does this by selecting an area of a map in the companion app (A C# .NET MAUI Blazor hybrid application), which then determines the optimal flight path for the drone. it then compiles this into a mission file and wirelessly sends it to the drone, which receives and processes the file using the Raspberry Pi companion computer. The companion computer then sends commands to the flight controller to fly the drone along the mission path and takes photos of the ground below. Once the mission has been completed the drone returns to where it was launched from and reconnects with the app to transmit the images, which the app stitches together to make the survey.
The TerraScan Mini drone is being developed using the PX4 open source flight framework, and is controlled by a PixHawk flight controller. This setup is capable of converting guidance commands into actual flight, and is capable of correcting for things like wind gusts that would knock it off course.
