Over the years there has been an urgent demand for improving the spatial resolution and accuracy of marine geoid models, that are needed for many engineering navigation, mapping, and research applications. Near-coast improvements in marine geoid modelling and determining sea surface heights (SSH) are expected from data assimilation of space-borne, in-situ and hydrodynamic model data. Sophisticated satellite altimetry re-tracking schemes are applied to derive near-coast SSH. Inter-comparisons of the two reference models (geoid and SSH) are conducted for detecting abnormalities. Identifying reasons for the detected discrepancies enables to determine whether these are due to poor hydrodynamic representation or/and geoid model errors. Both models can be improved iteratively, e.g. by acquiring new data over suspicious areas and iterative modelling. The developed theory is tested and improved in a study area (Gulf of Finland), that contains a long time span of many different data sources.

The main objectives of the project are: 1) Connection of tide gauge markers with the GNSS network geometrically by the geodetic SAR technique in order to determine the relative vertical motion and to correct the tide gauge readings. 2) Determine a GOCE based high resolution geoid at tide gauge stations in order to deliver absolute heights of tide gauges with respect to a global equipotential surface as reference. 3) Joint analysis of geometrical and physical reference frames to make them compatible, and to determine corrections to be applied for combined analysis of geometric and physical heights. These objectives are addressed by the project team with complementary expertise. The Baltic Sea serves as test area with very good geodetic infrastructure in order to identify the capabilities of the geodetic SAR technique for height system unification and determination of the absolute sea level at tide gauges.

Peep Sürje scholarship
Teedeehituse ja geodeesia sektori 26 ettevõtet ühendasid jõud, et toetada tudengite õppimist ning valdkonna arengut – loodi fond, mis sai nime valdkonna kunagise eestvedaja ja Tallinna Tehnikaülikooli endise rektori Peep Sürje järgi.
Fondist jagatavad stipendiumid on mõeldud Tallinna Tehnikaülikooli kuni kümnele inseneriteaduskonna teedeehituse ja geodeesia eriala 2. ‒ 7. semestri üliõpilasele, kes täidavad edukalt õppekava, on oma eriala fännid ning kelle eesmärgiks on areneda tipptegijaks.
