The integration of GNSS technology and the drone industry is helping to improve the work of drone pilots!

The job of a surveyor is to obtain accurate data. Moreover, the accuracy of the data relies on the skills of the surveyor and their expertise. In recent years, advancements in technology, including drones, have made the surveying process faster, safer, and more efficient. From the beginning, the establishment of ground control points (GCP) has been a necessary step in drone surveying, but advancements in GNSS technology have evolved the methods of Real-Time Kinematic (RTK) and Post-Processing Kinematic (PPK). However, each of these processes has its own advantages and disadvantages. *For more detailed information, please refer to the related links.
