Understanding High-Accuracy GNSS Workflows for Modern Drone Operations
RTK and PPK are often discussed together, but they solve accuracy challenges in very different ways. Understanding how each workflow functions helps operators choose the right tool for every mission, environment, and delivery timeline.
As drone platforms continue to mature, expectations around positional accuracy have risen just as quickly. In surveying and mapping, asset inspection, and research applications, meter-level accuracy is no longer sufficient. Data is expected to align cleanly with CAD drawings, GIS layers, and engineering models, often with centimeter-level precision.
Two of the most widely adopted techniques for achieving this level of accuracy are Real Time Kinematic (RTK) and Post-Processed Kinematic (PPK). While both rely on GNSS corrections, they differ in how corrections are delivered, when they are applied, and how they fit into real-world operations.
This article breaks down RTK and PPK in practical terms, using the integration of Sentera RTK and PPK workflows with Inspired Flight Technologies’ IF1200 or IF800 Tomcat aircraft as a real-world reference point.
