Get Coordinates for Ground Control Points with PPK Rover

Updated: Feb 25, 2022

Using the RoboDot, it's easy to obtain precise coordinates for ground control points (GCPs). GCPs can later be used in photogrammetry projects with Pix4D, Metashape Pro, or similar software. Here's a minimalist solution to acquiring GCPs with a single RoboDot Rover and freely obtainable observations from Continuously Operating Reference Stations (CORS).

First, know where your base or CORS corrections are located relative to your project. Increasing the distance between the base and rover will decrease the accuracy of each measurement. Distances between rover and base under 20km are recommended.

RoboDot allows users to choose between mounting it on a monopole, bipod or placing it directly on the point of interest to take a PPK rover shot. If you plan on returning, consider marking the location of the GCP with paint or a surveying pin.
