The Yuneec H520E camera drone is also available in a variant with RTK support. This system allows you to make photogrammetric measurements of exceptional precision, in a range of 1-1.5 cm. The system is ideally suited for surveyors and other users who want to generate professional, accurate orthophotomaps, 3D models or other surveying or construction documentation. In addition, the use of RTK makes it possible to improve the drone's stability in places where errors in reading the position from GPS may occur due to reflected signals (so-called multi-path error), e.g. next to tall buildings or in mountainous areas.
