Making use of aerial technology for aerial inspections, thermographic surveys, and mapping is an effective technique which is especially suitable because of the overall safety of the method and the lack of any requirement to halt work or transport, because it represents a contact-free methodology. SG Geotechnika holds an "Authorisation to Provide Aerial Services Using Unmanned Aircraft" issued by the Civil Aviation Authority. Currently, the company makes use of 2 unmanned systems (UAS) featuring cameras that record images in three spectral ranges. Thanks to this equipment, SG Geotechnika can provide all photogrammetric and thermographic imaging for various industries.
The Vespadrones Xyris 6 is a six-metre drone whose take-off weight is 9 kg and load capacity is 3 kg. It features a pluggable gimbal for various sensors, as well as a ballistic safety system. It may be used for autonomous flights to image mid-size and large areas, as well as for piloted flights for special applications where thermographic cameras are necessary. The DJI Phantom 2 is a four-engine drone whose take-off weight is 1.25 kg.
Its size makes it an excellent choice whenever imaging in close proximity to structures is required. It features an RGB GoPro5 camera that records detailed photographs from hard-to-access locations, and can fly even under stressful climatic conditions.
