Using the RTK Module with PPK
While RTK technology represents a major step forward from using satellite data alone (especially if it isn’t corrected with ground control points), it does have some limitations. For example, if your drone loses connection with the controller or satellite, then real time data transmission won’t be possible. Some jobs, especially longer ones in challenging terrain, make it difficult or even impossible to maintain stable data transmission.
As a result, the RTK system is not the only way surveyors and other drone professionals correct satellite coordinates and ensure accuracy. Another method is called “post-processing kinematics,” or PPK for short. While often talked about together, it’s important to note that RTK technology and PPK are actually quite different.
PPK requires essentially the same equipment as RTK but is run with a completely different workflow. Unlike RTK, a PPK workflow means you won’t require any real time corrections. Rather, the drone system stores data onboard the drone, and calculations post-flight combine both the aircraft data and base station data, producing results in PPK software on a computer. Data is created with geotag coordinates from an on-board GPS unit. Your base station, meanwhile, will also keep track of the drone’s positional information. These numbers can then be compared against each other after the completion of a flight.
While you don’t get the convenience of on-the-go corrections, a PPK system requires fewer transmissions and thus can get the job done even with a poor network signal reception or other obstructions. To maximize the potential and cover the limitations of each method, many top-shelf enterprise drone solutions utilize both RTK and PPK technologies to ensure the most accurate positioning possible. The Cloud PPK Service for DJI’s Phantom 4 RTK, for example, can be used to conduct calculations on the drone’s remote controller, in addition to the DJI GS RTK flight planning app. This setup also means you can adapt the Phantom 4 RTK to the workflow that makes the most sense for the job.
The resulting data can be quickly imported into DJI’s advanced mapping software, DJI Terra, for additional analysis.
