The Prototype of Orbital Database System for Satellite Tracking Information

Indonesia needs a satellite surveillance system for tracking its trajectory in real-time. Furthermore, this system is very useful in supporting the decision support system (DSS) through re-entry objects observation that has the potential to fall into Indonesian territories. System development leveraging a web-based application that can be easily accessed on various platforms. Commonly, applications rely on databases as the fundamental infrastructure for providing data input or storing the output produced by the model. Therefore, the proper database concept will enhance the application's reliability. This paper discusses the development of an orbital database system to support satellite surveillance applications. Our method combines relational and non-relational database approaches in collecting, querying, and writing data. We use a relational approach to store orbital parameter data from Space-Track API and a non-relational approach to record data yielded by the SGP4 model. As a result, this paper shows that our system can provide accessible data for the tracking application and display satellite trajectories map one hour ahead. In addition, we also present the orbital parameter information through a web-based catalog list providing detailed object properties.
