CAKAO - Combined analysis of kinematic orbits and loading observations to determine mass redistribution

Project: Research project

Project Details


The project focuses on the improvement of time variable gravity field information by consistent
combination of two different measurement techniques. Gravity field estimates derived from
GPS tracking of low Earth orbit satellites will be augmented by incorporating observations of
station displacements on ground. Permanently operating GPS stations worldwide provide
highly accurate measurements of the mass loading induced displacements, which will be used
to supplement and improve the satellite based measurements. Especially for continental areas, which are of high interest for different applications, e.g. Hydrology, an improvement in
terms of accuracy can be expected.
