AIUB/DGFI-TUM: PhD positions in reference systems


Dear colleagues,

In the framework of a collaborative project, the Astronomical Institute
of the University of Bern (AIUB, Switzerland) and the Deutsches
Geodaetisches Forschungsinstitut of the Technical University of Munich
(DGFI-TUM, Germany) are accepting applications for two PhD positions at
AIUB and one PhD position at DGFI-TUM.

Positioning, navigation and monitoring of the earth system, especially 
sea level changes, require a very precise and long-term stable, unique 
global reference. The International Terrestrial Reference Frame (ITRF), 
which is calculated on the basis of long observation time series from 
the space-geodetic techniques VLBI, SLR, GNSS and DORIS, provides the 
global reference. However, the accuracy and long-term stability are not 
yet high enough to capture small changes in the Earth system with the 
target accuracy of 1 mm and 0.1 mm/year. Technical advancements in 
observation methods are expanding their individual potential, but this 
has not yet been fully exploited for the ITRF. A new joint project of 
AIUB and DGFI-TUM aims to improve the accuracy and long-term stability 
of future ITRF solutions by more effectively utilizing the strengths of 
different geodetic space techniques.

The complete position description is available at

and

Please circulate this information within your institute.


With best regards
Manuela Seitz and Rolf Dach
