Post Processing GNSS Data with Emlid Studio

High-accuracy location information is critical for direct georeferencing or for ground control with UAS image photogrammetry. While we typically prefer to have real-time kinematic (RTK) GNSS data where corrections are being applied to our location measures in real time, that isn’t always possible or sometimes even desirable. In these situations, we can use a post-processed kinematic (PPK) approach to correct our GNSS data after the fact. This requires that we have a RTK/PPK capable GNSS receiver and either a local base station or access to correction files from a nearby reference station (e.g., a CORS network site). In some cases, PPK can provide more accurate results than RTK because there are no transmission lags between the base and rover to worry about. In this walkthrough we'll use a free software app called Emlid Studio to post-process data collected with our Emlid Reach RS GNSS system.
