Rtk Gps for ground control points drone surveys

We supply RTK GPS Systems for ground control points What Are Ground Control Points? And, Their Role in UAV Mapping…. If you are a part of the UAV mapping industry, you must be aware of Ground Control Points (GCP’s). Ground Control Points can help you create more accurate drone maps. There are different kind of GPS available, each with varying accuracy. For creating Ground Control Points, you need to use RTK — GPS or PPK — GPS. RTK GPS or Real Time Kinematics can help you create drone maps with an accuracy level of 2 cm to 6 cm. Whereas PPK GPS or Post Processing Kinematics is even more accurate, and you can expect mm grade accuracy in UAV mapping. There are different kind of GPS available, each with varying accuracy.

And this is because of earth’s uneven surface which can be likened to a piece of crumpled paper. This makes collecting good elevation data particularly difficult. Particularly, if you need a survey team to sign off on your drone model, they will not do so unless you use GCP’s.
