Power lines inspection

The Geoscan Group of Companies provides monitoring with an unmanned aerial vehicle (UAV).

Monitoring with an UAV equals in-situ one and sometimes surpasses it. For instance, when determining the distance between overhead line towers, data inaccuracy with an UAV is less than 10 cm while manual GPS receivers may contain inaccuracy up to 5 m.

Since 2016 the Geoscan Group of Companies has carried out projects on aerial survey of PTL for Russian and foreign companies by using their own UAVs. The whole length of surveyed PTL is more than 20 000 km.

Besides the report and described data, specialized “Sputnik LEP” GIS with uploaded results of the survey is provided.

Sputnik LEP is a convenient instrument to analyse and inspect PTL.
