DJI Phantom 4 RTK

Recommended Field Workflow for PPK Processing

Equipment Needed

  • DJI Phantom 4 RTK Aircraft

  • Dual-band GNSS base station (e.g. Trimble R10, Leica GS16, or similar)

Note: this workflow does NOT utilize the DJI D-RTK2 base station.  Our testing has shown that utilizing 3rd party base stations from providers like Trimble or Leica produces more reliable results.

Field Collection Procedures

  • Set up your base station

    • Collect L1/L2 observations at a minimum of 1Hz (5Hz or 0.2 second observations are preferred, but not necessary)

    • If possible, set up your base station over a known point

    • Ensure your base station is setup to collect and store raw RINEX data (.19o and .19n files)

  • Set a minimum of 3 ground control points

    • These are used as check points to validate the accuracy of the RTK data

    • For large projects, we recommend 3 ground control points per flight

  • Fly your site to collect data using Aerotas’ best practices

Data Upload Procedures

Go to aerotas.com/upload to upload your data.  Be sure to include the following files:

  • Photos captured by the drone (.JPG)

  • GNSS files stored on the drone (EVENTLOG.bin, PPKRAW.bin, Rinex.obs and Timestamp.MRK)

  • Base Station RINEX and Navigation data files (.19o, .19n)

File Deliverables

Standard deliverables include a full-resolution orthophoto and digital surface model.
