Online Precise Point Positioning (OPPP) for Low-cost GNSS Sensors

Status: Abgeschlossen, August 2013

Bearbeitung: M.Sc. Paola M. Gonzalez

In this master thesis, a MATLAB algorithm was implemented to compute absolute SSR-related positions from single frequency receiver observations. The goal was to use open IGS SSR-products, like precise orbits, ionosphere information and stable models for the processing.
