Prof. Dr. Guenter W. Hein
is Director of the Institute of Geodesy and Navigation of the University FAF Munich. Present research activities include high-precision positioning and navigation using satellites and the combination with other terrestrial sensors. Prof. Hein´s main interest is the development of Galileo, Europe´s global navigation satellite system, where he serves as German delegate in the EC Galileo Signal Task Force. Prof. Hein received 2002 the Johannes Kepler Award for "sustained and significant contributions to satellite navigation" from the US Institute of Navigation.
Lecture: GNSS Under Development and Modernization
During this 90 minute lecture, Professors Per Enge and Guenter W. Hein will describe the worldwide development of GNSS. The following systems and developments will be summarized: modernized U.S. Global Positioning System, Wide Area Augmentation System, Russian GLONASS, European Galileo System, Chinese Compass System, Japanese Quasi-Zenith Satellite System, Indian IRNSS, Nigerian NIGCOMSAT. Finally, Professor Hein will provide a summary of all the worldwide developments.
Lecture: Constellations and Orbit Determination
During this 90 minute lecture Professor Hein will describe the different types of precise orbit determination. After reviewing fundamentals of celestial mechanics like Newton's equation of motion and Kepler´s laws, the general model of dynamic orbit determination and its solution is presented. The main perturbing force models are described as well as the relativistic corrections. Special emphasis is put on the GNSS force models and ephemeris representation. Finally GNSS orbit determination and time synchronization is summarized including pre-processing and validation, in particular in the context of Galileo.
