Description

A Ground Penetrating Radar (GPR) mounted on a drone enables to see through the surface of ground, ice, rocks, freshwater, and buildings or through structures at unsafe and hazardous environments without compromising the safety of staff, providing an additional solution for more efficient surveying.

Currently, SPH Engineering provides two configurations for the GPR-drone integrated system setup. Both are using DJI M600 Pro drone and Radarteam Cobra Plug-In GPR, but the antenna is different in each setup:

 - SUBECHO-70 (SE-70) antenna

 - SUBECHO-150 (SE-150) antenna

Antennas differ in their frequency range and centre frequency. SE-70 has a centre frequency of 80 MHz and can penetrate the ground more – up to 80 meters in good conditions (ice or dry sand). SE-150 has a centre frequency of 124 MHz and penetration up to 40 meters in good conditions, however, the resolution is much better.

Mapping of underground infrastructure

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.

Please note that the current GPR-drone integrated system does not enable to map small or thin objects such as cables or thin pipes. It is capable of detecting objects with an approximate size of 5 - 10% of depth, such as concrete sewage channels, tunnels, bunkers, etc.

Specifications
