How to log data for PPP services

This guide shows how to record logs for Precise Point Positioning (PPP) and download them from Reach M+/M2 using ReachView 3.

Precise Point Positioning or simply PPP is a technique that requires processing a raw data log from the standalone receiver for further removing or modeling GNSS system errors to provide a high level of position accuracy.
