National and regional geoid computation

With the ever increasing use of global positioning systems, requirements for the accuracy of geoid models are under constant revision. The research on national and regional geoid computation aims to improve geoid models for Finland and other regions. In the research we incorporate results of the global gravity satellites CHAMP, GRACE and GOCE.
