TL;DR
This paper develops a formal ontology for satellite databases, enabling better data sharing, integration, and domain understanding in space situational awareness.
Contribution
It introduces the UCS Satellite Ontology (UCSSO) and demonstrates how it can reuse or replace existing space domain ontologies like SSAO.
Findings
UCSSO facilitates semantic data integration for satellite databases.
The ontology can reuse, extend, or replace SSAO in different applications.
The ontology resources are publicly available online and on GitHub.
Abstract
This paper demonstrates the development of ontology for satellite databases. First, I create a computational ontology for the Union of Concerned Scientists (UCS) Satellite Database (UCSSD for short), called the UCS Satellite Ontology (or UCSSO). Second, in developing UCSSO I show that The Space Situational Awareness Ontology (SSAO) (Rovetto and Kelso 2016)--an existing space domain reference ontology--and related ontology work by the author (Rovetto 2015, 2016) can be used either (i) with a database-specific local ontology such as UCSSO, or (ii) in its stead. In case (i), local ontologies such as UCSSO can reuse SSAO terms, perform term mappings, or extend it. In case (ii), the author's orbital space ontology work, such as the SSAO, is usable by the UCSSD and organizations with other space object catalogs, as a reference ontology suite providing a common semantically-rich domain model.…
