Data Driven Thermospheric Density Modeling with Machine Learning

An ontology of and for space traffic management.

The OSEO (or OSO-Orbital Space Ontology) is conceived as an alternative to the SSAO. The latter was originally described as the overall domain, but by demarcating the domain more precisely the OSEO/OSO name may better capture the overall domain. Name change is TBD, pending further researcher and domain demarcation.
