The system consists of a UAV integrated with Ground Penetrating Radar (GPR). The full integration is ensured by adding the onboard UgCS data logger to the system. Drone's flight is planned and managed using the full functionality of UgCS.
You can choose between a ready-to-use system or components like the UgCS data logger integration kit for self-assembling.

The GPR-drone integrated system enables to measure the depth of water or profiling the bottom of freshwater rivers, lakes, ponds up to 15 meters in depth.
Benefits – possibility to do work even when the water is frozen or the surface of the water is partially covered with ice. Compared to bathymetry using a boat (equipped with echo sounders) the drone with a GPR provides better accuracy in following survey lines thanks to the inbuilt GPS and automated flight. Also, in most cases, a drone makes it a lot easier to deliver the necessary equipment to the desired area.
The results displayed in Figure 3 were gathered with the drone flying at an altitude of 20 meters above the water surface level to profile 8 meters deep frozen lake.

Soil layer profiling is a standard task that needs to be done before any serious area development or construction works. The standard technique is drilling dozens of holes or conducting a GPR survey on carts.
GPR-drone integrated system delivers higher work productivity and enables safer work conditions for the personnel in cases of rough terrain.
GPR allows finding any potentially dangerous underground water streams or lakes.
Data gathered by GPR-drone integrated system flying at an altitude of 5 meters over an asphalt-covered car parking lot is displayed in Figure 4. The soil layers are clearly visible.

Mapping of underground infrastructure is an important task before starting any construction works on previously developed territories or in cases when actual documentation and maps for underground infrastructure is missing.
Acquire best possible data by flying the GPR as low as possible mimicing the relief of the surface.
True Terrain Following enables the drone to fly at low altitudes (up to 1 meter) without a need to import precise Digital Elevation Model (DEM) height-map into UgCS.
