Väisälä Foundation: Earth radiation and satellite orbits

Projekt: Forskningsprojekt

Projektinformation

Allmän beskrivning

Precise Orbit Determination (POD) is involved in all satellite-based research and provision of related services, as well as for monitoring of space debris. For kinematic and dynamic POD, all factors perturbing the orbits need to be considered. We focus here on Earth radiation pressure (ERP) due to reflected solar radiation and thermal emission from the Earth system. Although it is an order of magnitude smaller than the direct solar radiation pressure, it is one of the least known orbit perturbation factors. Our vision is to significantly improve computation of ERP, and thus accuracy of POD.
