PPK Precision Add-on for Phantom 4 RTK
Fail-safe surveying with the world's most compact
RTK drone

Our PPK Worflow for DJI Phantom 4 RTK

RTK-accurate measurement even without live correction data

  • PPK calculation of camera positioning with a very high accuracy (up to 1 cm e.g. with SAPOS correction data)
  • Elimination or shortening of the duration of the RTK fix loss
  • Enables surveying with only a few GCPs
  • Eliminates the need for LTE, UMTS, GPRS or GSM coverage and permanent communication between drone and base station during the mission
  • Thus no danger of aborting the mission due to signal loss
  • Highest accuracy using free selection of satellites and satellite types as well as further parameter adjustments for position calculation in the PPK process
  • Prevention of typical RTK errors (e.g. cycle slips) through forward and backward calculation of the positioning

System specifications (UAV + Add-on)

GSD (Altitude/36,5) cm/Pixel
Max. Operating area* 1 km²
Mapping Accuracy The relative deviation of the drone camera position to the phase center of the built-in D-RTK antenna has already been applied to the image coordinates stored in the EXIF metadata
Data Acquisition Efficiency** 5 cm (absolute horizontal precision for photogrammetric models)
* For a single flight at an altitude of 182 meters. This results in a GSD of approx. 5 cm/pixel and meets the requirements of the ASPRS Class III accuracy standard for digital orthophotos.
** At an altitude of 100 meters, 2.7 GSD, sunny conditions. Mapping accuracy meets ASPRS Class III accuracy standards for digital orthophotos. Actual accuracy depends on lighting conditions and patterns, drone height, mapping software used, and other factors during shooting.
