STRAMIK – Struktural analysis with microwave interferometry

Research area: Mikrowave interferometry

STRAMIK was a project conducted in contract for the German railways (DB Netz AG). In a first phase the potential of microwave interferometry for the structural analysis of building structures was demonstrated, in order to support and validate the static and dynamic modeling. In STRAMIK bridge constructions were the primary subjects. In a second phase the research-like prototypic methods of microwave interferometry were adapted to railway-specific structures and optimized for a largely automated routine operation on-site at railway bridges.

RESAH – Reprocessing of data of the Hessian SAPOS network and analysis of station stability and velocity field

Research area: GNSS, Geokinematics

Data of the Hessian SAPOS network of the period 2003 to 2012 has been reprocessed according to IERS conventions and recommendations of the IGS. Based on the reprocessed daily network solution the time series of station positions have been analysed and a velocity field estimated. The significiency of intra-plate motions has been assessed and a comparison with geological models was carried out. The research project was funded by Hessisches Landesamt für Bodenmanagement und Geoinformation.

Funding period: 2011 – 2014

GNSS Real Time Monitoring

Reseach area: satellite geodesy – GNSS

The goal of the project, which was a joint effort between PSG and Bundesamt für Kartographie und Geodäsie (BKG), who was responsible for the funding, was the development of a GNSS Real Time software for monitoring the BKG EUREF and GREF stations. The GMON software made the real time monitoring of the data quality and the coordinates of the BKG permanent stations possible. In a further development the GEORB software was created on the basis of GMON to estimate clocks for the GNSS satellites. The goal was to offer real time streams for the precise point positioning with PPP via NTRIP. The project was completed 2014.

GPS Seismic

Reseach area: satellite geodesy – GNSS

In cooperation with the Real Instituto y Observatorio de la Armada en San Fernando, ROA, Spain, PSG developed a real time analysis and evaluation method to process high frequency data from GNSS permanent stations (continuously operating GNSS reference stations, CORS). The goal of the project was to expose transient signals, which had been caused through seismic activities, especially earth quakes and tsunamis, in GNSS time series in real time. The project concentrated on the high frequent CORS in Spain and Morocco, i.e. the tectonic zone in the area of the Strait of Gibraltar. The results were published in the PhD thesis of L. Mendoza (

IGS station Addis Ababa

Reseach area: satellite geodesy – GNSS

In joint cooperation with the Geophysical Observatory of the University of Addis Abeba, Ethiopia and the Bundesamt für Kartographie und Geodäsie, Frankfurt am Main) PSG installed a IGS station on the campus of the Addis Ababa University.

International collaboration in satellite geodesy

GEO2TECDI is a joint Thailand-EU project to enhance skills and joint research capabilities of Thai researchers in applying and exploiting three space geodetic techniques, namely Global Navigation Satellite System (GNSS), Interferometric Synthetic Aperture Radar (InSAR) and Satellite Altimetry (SALT), for the detection, monitoring and modeling of land surface motion and deformation due to tectonic processes, land subsidence and sea level change. The project under the lead of TU Delft comprised the Chulalongkorn University in Bangkok, the Ecole National Superieure Paris and TU Darmstadt. PSG dealt with GNSS, Altimetry and GRACE.

Duration 2009 bis 2014.


Research area: satellite altimetry

Within project RECOSETO (REgionalCOastalSEa level change and sea surface Topography from altimetry, Oceanography, and tide gauge stations in Europe) funded by the German Research Foundation DFG PSG analyzed the Sea Surface Topography in Coastal Zones.

Funding Period: 2007 – 2009


Research area: satellite altimetry

Project STREMP (Spatial and Temporal resolution limits for REgional Mass transPort and Mass distribution) was funded in the framework of the DFG Priority Pogramme SPP 1257 „Mass Transport in the System Earth“. Goal was the determination of gravity variations due to mass variations in the Mediterranean and Black Sea, see STREMP project web page.

Funding Period: 2007 – 2011

Coastal sea level (COSELE)

Research area: satellite altimetry

Satellite altimetry in the coastal zone has the potential to yield a large amount of unique information for coastal management and long-term monitoring of sea level change. Project information on website of Deutsche Forschungsgemeinschaft.

Funding period: 2011 – 2016

Exupéry: Managing Volcanic Unrest – The Volcano Fast Response System

Research area: microwave interferometry

The project was funded in framework of the Geotechnology program of the Ministry of Research and Technology. The main goal of this project was to develop a hybrid, ground based, continuous deformation monitoring system, consisting of the ground based Radar IBIS-L and a network of geodetic GPS receivers, and to integrate the system in the “Volcano Fast Response System” (VFRS) with the intention to deliver nearly on line terrain displacements and surface mass movements. The VFRS was successfully tested at the volcano Fogo on the Acores. EXUPERY final report.

Duration 2007-2010.
