What is the definition of Post-processed kinematics (PPK)?
Stands for post-processed kinematics. PPK is an alternative technique to RTK usually delivered as a service or software application. With PPK workflow, GNSS correction information is applied post-mission, so is not suited to application requiring real-time corrections. It can, however, also provide the most accurate result with down to 0.008 m.
Example image showing GNSS satellite signals (red lines) to base station (left) and rover (centre). Corrected satellite data (green lines) is broadcast by base station for real-time solutions and archived for post-processing solutions. PPK solution (right) analyzes and processes archived correction data and GNSS data from mission (blue lines).
