Get Started with WingtraOne PPK

The WingtraOne PPK (post processing kinematics) enables high-precision mapping without the need of using GCPs (ground control points) to correct a map that is created based on images captured by the WingtraOne. The geotags of the images are corrected to centimeter precision after the flight by relative comparison of the satellite logging of WingtraOne PPK to a base station operating as reference station on the ground.


Together with your WingtraOne PPK unit you will receive a brochure. It guides you in how to deploy the PPK module and our PPK processing software WingtraHub. Furthermore it gives a summary of the PPK workflow.

If you bought a WingtraOne directly with PPK option, the PPK module will be already installed when you receive your unit. If you ordered the WingtraOne PPK add-on then you have to install PPK module on your WingtraOne by following the instructions in the Wingtra Support Doc - Install PPK module.

WingtraOne PPK processing is done using WingtraHub Windows Software. To install and run a tutorial project follow the instructions in the Install WingtraHub - PPK processing toolchain article.

Further information about the required base station data and the different options to obtain PPK correction data are detailed in the PPK Base Station article.

PPK Briefly Explained


Post processing kinematics (PPK) uses correction data of a fixed base station on ground to correct the GNSS data of WingtraOne after your flight. It allows assignment of centimeter precision geotags to your images. This geotagging process happens within the Windows WingtraHub application after your flight(s), typically back in the office. You will need the following data:

  1. Images from camera on WingtraOne
  2. GNSS data from PPK module on WingtraOne
  3. Base files (RINEX) from your base station
  4. Base location of your base station in ITRF based coordinate system with elliposidal height

To acquire images and the GNSS data, you need a WingtraOne PPK drone with which you perform a normal flight. All data will be saved to the camera SD card in an organized manner, focus on your flight - WingtraOne will ensure that your data (images and GNSS data) is saved on the SD card.

Correction data of the base station is logged into "Receiver Independent Exchange Format (RINEX)" files. You have to provide these base files (RINEX) and the exact location of your base station.

The images will be tagged in WGS84 coordinates (if base location is given in WGS84) with ellipsoidal height. Together with the tagged images, WingtraHub will save a geotags.csv file and a geotagging report for every project. The geotags.csv file contains the following columns: image_name, lat, lon, alt, 0, 0, 0, horizontal accuracy, vertical accuracy. PPK geotagging is not adding attitudes to the csv file, this is why you will see 3 columns with value zero. Due to the high-precision position information, the final accuracy in the map is best if no attitude information is used while processing.
