We look at what are GCPs (ground control points), their importance for accuracy of drone mapping and compare them with RTK/PPK methods.

GCPs, RTK or PPK - which method is the best for accurate drone mapping and 3D models? We explore the pros and cons in this post.

In this article, we look at how drone PPK works and how Hammer Missions can be used to create RINEX files for drone PPK workflows.
