RTK v/s PPK Drones: What's the best?

If you’re a drone enthusiast, you’ve probably heard terms like PPK, RTK, and GCP. Well-known drones on the market, such as the M300 RTK and Phantom 4 RTK, have these acronyms in their titles. But – what exactly are PPK and RTK? What are RTK and PPK drones used for? Which gives the best results? Do these questions confuse you? is for Simply put, the main difference between them occurs during position correction. RTK is fixed in flight, PPK is fixed later. Both methods correct for positional errors in drone mapping data and eliminate the need for GCPs, resulting in cm (sub-inch) absolute accuracy.

Drones are proving to be an invaluable asset in a variety of industries, including public safety, oil and gas, energy and utilities, construction, and agriculture. Drone-based solutions are an economical, practical, efficient and accurate alternative to existing workflows. Always remember that the efficiency of your investigation is related to choosing the right remediation method. But before getting to the heart of the matter, it’s essential to understand the concepts of GPS, GNSS, and GCPs.
