Global Navigation Satellite Systems are the main method of positioning for geo-information data collection. However, ‘standard’ GNSS is often not accurate enough for that purpose. As a result, various augmentation techniques have been developed over the years. Examples are (public) Space Based Augmentation Systems (SBAS), Real Time Kinematic dGNSS (RTK) and Precise Point Positioning (PPP). Each of these techniques has its own advantages and disadvantages. In this E-learning you will learn about the differences between the various GNSS augmentation techniques.
