If you fly a WingtraOne drone, you can use the Propeller PPK workflow to process the images with high accuracy. For most sites, the Phantom 4 RTK (P4R) with the Propeller PPK workflow will be sufficient, but for certain sites or situations, a vertical take off and landing (VTOL) drone, such as the WingtraOne, is the better solution.
When using a WingtraOne there are some considerations you must make to produce as accurate of a model as possible. Here is a list of the items you should consider.
Although AeroPoint 2s are required for most situations, there are circumstances where a model can be produced using AeroPoint 1s, such as sites located in the Propeller Corrections Network (PCN) and set up on a published coordinate system. Please see the figure below for specific ground control requirements for Propeller PPK with WingtraOne.
Camera and Mission Settings
Propeller recommends the following mission settings:
The recommended camera settings change depending on your hardware.
These settings should produce the most accurate final model, but adjustments may be necessary depending on weather conditions, lighting, etc.
You do not need to geotag the images in WingtraHub when using Propeller PPK.
Upon the drone’s first upload, you will be prompted to register the drone in Propeller.
The WingtraOne saves GPS information necessary for PPK processing in .SBF and .JSON files. You can either drag both the DATA and IMAGES folders for each flight, or drag the entire project folder(s), into Propeller during the upload process, as shown below.
If you have already geotagged in WingtraHub, additional files will be created and placed in the DATA folder. Please do NOT include these additional files when uploading using Propeller PPK. The only two files from the DATA folder that should be uploaded with your images are FlightName WingtraOne.SBF and FlightName.JSON.
In most cases, if you are using the WingtraOne PPK drone with Propeller AeroPoints, you do not need to use WingtraHub to geotag your images before uploading. You could simply proceed with Propeller’s PPK workflow.
However, there are some situations where you would use WingtraHub, including:
- You do not use AeroPoints.
- You have your own base station.
- You have only AeroPoint 1s and you are not within the Propeller Corrections Network (PCN).
- You have only AeroPoint 1s and are on a local grid site.
Please talk to your assigned customer success engineer or Wingtra Support about any other situations.
