Get started with WingtraOne PPK

WingtraOne post processing kinematics (PPK) enables high-precision mapping without the need for ground control points (GCPs) to correct a map generated from its captured data. Geotags on the images are corrected to centimeter-level precision after the flight. This happens through relative comparison of WingtraOne PPK raw measurements of satellite locations to raw measurements obtained through a base station operating as a reference station.


To understand how to get started with your WingtraOne please read this article. It guides you on how to deploy the PPK module and our PPK processing software WingtraHub. It also provides a summary of the PPK workflow.

All WingtraOne GEN II drones are equipped with a high-precision GNSS board and
antenna to produce centimeter-level accuracy with post-processed
kinematic (PPK)

WingtraOne PPK 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.

WingtraOne PPK module

The WingtraOne GEN II PPK module records signals from the following constellations:

  • GPS (L1, L2)
  • GLONASS (L1, L2)
  • Galileo (L1)
  • BeiDou (L1)

All WingtraOne GEN II drones with a Mosaic receiver have quad-constellation enabled by default. WingtraOne GEN II drones with an AsteRx receiver will be upgraded with the 2.12.1 version to enable quad-constellation

From the 2.12.1 version, WingtraHub supports multi-constellation for PPK processing to increase the accuracy of geotagging, even in challenging environments.

WingtraOne GEN I PPK module supports signals from GPS and GLONASS only. 

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-level 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 WingtraOne camera
  2. GNSS data from the WingtraOne PPK module
  3. Base files (RINEX) from your base station
  4. Base location of your base station in ITRF-based coordinate system with ellipsoidal height

To acquire images and the GNSS data, you need a WingtraOne PPK drone, with which you will 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, omega, phi, kappa, roll, pitch, yaw, horizontal accuracy, vertical accuracy, accuracy roll/omega, accuracy pitch/phi, accuracy yaw/kappa, coordinate system, vertical coordinate system and time. The high precision image geolocation and exterior orientation parameters result after processing in a high accuracy map.
