To get highly precise camera coordinates, there are two type of camera positioning systems on the market; real time kinematic (RTK) with corrections from a base station via a radio link while the drone is flying, and post processed kinematic (PPK) that doesn’t require real time base station data during the flight. Klau Geomatics Pty Ltd have developed a plug and play PPK system that works with virtually any drone and any camera. It captures camera exposure events with the GNSS data from a quality Novatel GNSS board. The photo centres are then input into the photogrammetry workflow with a proven, repeatable accuracy of 0.03m achieved over the entire project area. It is essential to know that the data you produce from your drone is reliable, repeatable and accurate. Klau Geomatics is working to further automate the PPK workflow and streamline precise map production from any drone. www.geomatics.com.au
