I investigates how optical atomic clock-based geopotential measurements can be integrated with existing geodetic techniques (GNSS, gravimetry, leveling) to improve the accuracy and temporal stability of Finland’s vertical reference frame.
The goal is to design an optimal measurement strategy for using clock data to refine the Finnish geoid and vertical datum, while better capturing geophysical processes such as Glacial Isostatic Adjustment (GIA) and seasonal hydrological variations.
Accurate height systems are essential for infrastructure planning, flood risk management, navigation, and climate change monitoring. Finland faces unique challenges due to GIA and water loading effects, which cause continuous height changes.
I uses a simulation-based approach with generation of synthetic observations, geoid computation and assessment to quantify the effect of atomic clock measurements.
