CENTIMETER LEVEL POSITIONING SYSTEM – PHANTOM 4 RTK
A new RTK module, integrated directly into the drone, provides real-time, centimeter-level positioning data. A non-RTK drone requires more ground control points (GCP) per square kilometer which can take several hours to place. The Phantom 4 RTK has an in-built centimeter-accurate RTK navigation positioning system. In addition, it has a high-performance imaging system. This reduces the number of GCPs, which saves at least 75% in set-up time. Sitting just beneath the RTK receiver is a redundant GNSS module, installed to maintain flight stability in signal-poor regions.
The RTK module can provide positioning accuracy of 1cm+1ppm (horizontal), 1.5cm+1ppm (vertical). Uniquely, the P4 RTK can get 5cm absolute horizontal accuracy of photogrammetric models. This drone can be integrated into any workflow, with the ability to connect its positioning system to the D-RTK 2 Mobile Station, using a 4G dongle or a WiFi hotspot.
