Real-Time GNSS

Precise global navigation satellite system (GNSS) applications in the Earth and atmospheric sciences, navigation, surveying and mapping, as well as early warning systems for geo-hazards require solutions not only of high accuracy, integrity, and continuity, but often also an availability in real-time with a delay of only a few seconds. The group has been developing and operating a real-time precise positioning service since 2007, and as one of the real-time Analysis Centers of the International GNSS Service (IGS) provides corrections to the GNSS community. Our real-time products and observation data can also be accessed through our GNSS Caster.

The research focuses on developing theory and methods for improving the performance of multi-GNSS solutions, on the use of low-Earth orbit (LEO) satellites for positioning and atmospheric sensing, and on geoscience applications using real-time site displacements or ionospheric electron density variations for the monitoring of geohazards such as earthquakes and tsunamis.
