Flowchart of the local troposphere augmentation for real-time (RT) PPP. The server end (top green box) determines the real-time ZWD fitting coefficients which are broadcast to the users. The user end (bottom red box) utilizes the real-time orbit/clock corrections and the real-time ZWD fitting coefficients to perform real-time PPP with local troposphere augmentation.
