DroneDeploy and Trimble focuses on the accuracy of drone surveying techniques.

This whitepaper from DroneDeploy and Trimble focuses on the accuracy of drone surveying techniques, specifically Real-time Kinematic (RTK) and Post-Processed Kinematic (PPK) workflows. The paper investigates the accuracy of different PPK correction methods, including Trimble's Applanix POSPac PPK with PP-RTX service and local base station corrections, as well as how the number of Ground Control Points (GCPs) and flight duration affect accuracy. It also compares the accuracy of PPK workflows with RTK workflows and outlines recommendations for choosing the most appropriate workflow based on job site requirements.
