Graz University of Technology - Institute of Geodesy/ Working Group Navigation

Teaching and research focuses on the complete aspect of navigation, which means that the thematic work goes beyond the determination of positions and trajectories, and also covers the sub-aspects of route planning and guidance. As far as Global Navigation Satellite Systems (GNSS) are concerned, the Institute of Geodesy was involved in research and development from the very beginning.

Regarding trajectory determination, the current topics mainly cover multi-sensor systems, e.g. the fusion of GNSS, INS including Kalman and particle filtering. Specific applications are autonomous driving, drone steering, pedestrian navigation, etc. Another research area is the determination of the Earth's gravitational field with the necessity of the provision of geoid heights with high accuracy for local to regional applications.

• Earth gravity field determination
• GNSS applications (GPS, GLONASS, Galileo)
• Precise Point Positioning (PPP)
• Sensor integration of GNSS and INS

The Institute of Geodesy owns a highly accurate Inertial Measurement Unit (IMU) which can be used as a sensor in multi-sensor environments. Mounted on a vehicle-based measurement platform, the existing IMU provides a way to verify cheaper and smaller sensors (MEMS, etc.) for their quality.
