PPK
Pre-Flight PPK Assessment
-
Verify Flight Time: Always confirm flight times for PPK maps are more than the specified times for certain regions. This is required for the corrections to be accurate.
- 10 or more minutes of flight time is required
- RTK Module: Ensure that the RTK module on the drone is mounted even for PPK flights

FAQs
What should I expect in terms of accuracy?
Expected accuracy is < 3 cm horizontal RMS error and < 6 cm vertical RMS error. This is independent of the region as long as the solution has converged. Ensure you have checkpoints in place to validate accuracy.
When is my drone collecting observations?
While powered on with an RTK module attached
Do I have to fly with DroneDeploy’s Flight App?
No, we support processing of data sets captured in a variety of ground control apps.
Do I still need GCPs or Checkpoints?
As with RTK, PPK maps will generally be more accurate than a non-RTK/PPK map without GCPs. DroneDeploy still recommends the use of GCPs for the highest level of absolute accuracy (as well as checkpoints to verify against known benchmarks).
