The Implementation of DBLC Design Model for Orbital Database System

Abstract

Surveillance of artificial space objects must be performed, especially for re-entry objects that have the potential to fall into Indonesian territory. This system requires a database that contains the orbital parameter information of every artificial object orbiting the earth. The purpose of this paper is to design a database model by applying the DBLC method for the artificial space object surveillance system. Data sources are from a satellite catalog and bulk-TLE of all active and decayed objects derived from the Space-Track. Those data are aiming as input for the real-time surveillance system of re-entry artificial space objects and the web-based informative catalog of all artificial space objects with their properties. The result of the design is a relational database consisting of 7 tables and 6 relations. Hopefully, this design can assist in developing a surveillance system of artificial space objects and the orbital database information system for all objects registered in NORAD.
