The usage of signals from Global Navigation Satellite Systems (GNSS) has revolutionized numerous applications in different areas of our society since the nineties. The most obvious examples of this development are probably the surveying and mapping and the usage of route guiding systems in almost every private car.
However in parallel GNSS techniques are nowadays also established for various geoscientific applications in Earth Observation. For this purpose receiver platforms as ground stations, vehicles, aircrafts, ships or satellites are used to cover the broad range of spatiotemporal scales of the investigated geophysical phenomena. One of the biggest successes hereby is the continuous and day-by-day use of GNSS data to improve regional and global weather forecasts since 2006. A major recent research focus is the usage of GNSS signals from water, ice, and land surfaces for remote sensing.
The topic area GNSS Remote Sensing, Navigation and Positioning at TU Berlin has these research topics:
- Development and improvement of scientific GNSS analysis software for Earth observation applications with focus on atmosphere sounding and remote sensing of water, ice, and land surfaces,
- Operational processing of satellite and ground based GNSS atmosphere sounding data and provision of corresponding data products for weather services,
- Development and application of GNSS analysis software considering real-time aspects for the application in Early warning systems and for atmosphere sounding,
- Multidisciplinary applications of GNSS based Earth Observation data for geosciences and for environmental monitoring,
- Development and realization of new satellite missions with GNSS components for precise orbit determination, atmosphere sounding and reflectometry,
- Development of specific and scientific GNSS receivers for GNSS Earth Observation applications.

A highlight of the scientific activities in the topic area during the recent years was an innovative climate research experiment with focus on Polar regions. This experiment was proposed within the Earth Explorer 9 call of the European Space Agency ESA by a large international team of scientist and engineers under joint lead of IEEC Barcelona and TUB/GFZ: G-TERN .
