Preliminaries of a Space Situational Awareness Ontology [PDF]
CoRR, 2016 Space situational awareness (SSA) is vital for international safety and security, and the future of space travel. By improving SSA data-sharing we improve global SSA. Computational ontology may provide one means toward that goal. This paper develops the ontology of the SSA domain and takes steps in the creation of the space situational awareness ...

Advances in soft X-ray emission of the Earth's magnetosphere
地球与行星物理论评, 2023 The coupling between solar wind and the magnetosphere and the dynamic processes in geo-space are the basic driving factors of space weather. Understanding these processes on the system level is essential to the studies of space physics and space weather.
