Workshop 2017

Global GNSS processing based on the raw observation approach

Workshop 2017 - Sebastian Strasser - GNSS processing similar to that of the IGS analysis centers (AC) is performed at Graz University of Technology (TUG) using the raw observation approach. This new approach offers some benefits compared to well-established approaches, such as a straightforward incorporation of new observables due to the avoidance of observation differences and linear combinations. GNSS products generated at TUG currently comprise GNSS satellite orbits and clocks, station positions and clocks, and code and phase biases. To evaluate the new approach, products generated using the GPS constellation and observations from the IGS station network are compared to those of the IGS ACs. The comparisons show that the products generated at TUG are on a similar level of quality to the products determined by the IGS ACs.
