The system consists of a UAV integrated with Ground Penetrating Radar (GPR). The full integration is ensured by adding the onboard computer UgCS SkyHub 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 SkyHub integration kit for self-assembling.

The webinar gives an introduction to the use of #airborne #GPR on #drones - the possibilities offered by the GPR+drone integrated system. The webinar covers the basics of Ground Penetrating Radar (GPR) usage with a drone:
Radar Systems Zond-12e #Drone 1000a #GPR system is applicable to detect small objects with a diameter starting from 8cm and pipes/cables with a diameter starting from 3cm. The GPR+drone integrated system can be used both with a drone or for terrestrial surveys if conditions don't allow to use a drone.
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. More detailed about airborne GPR for bathymetry >>>
The result displayed in Figure 3 was gathered with the drone flying at an altitude of 2 meters above the water surface, speed 2 m/s. Airborne GPR datasets >>>
Strata 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 on the drone flying at an altitude of 1 meter over an asphalt-covered car parking lot. The 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 the best possible data by flying the GPR as low as possible mimicking the relief of the surface. Adding an altimeter to the system will enable to fly in True Terrain Following mode.
UgCS SkyHub 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.
