Electrical Ground Support Equipment (EGSE)Design for Small Satellite

摘要

This paper describes EGSE design for the small satellite such like KOMPSAT-2 satellite. Recent design trendrnof small satellite and EGSE is to take short development time and less cost. For this purpose, the design forrnKOMPSAT-2 satellite and EGSE are not much modified from KOMPSAT-1 heritage. It means that it is able to bernaccommodated the verified hardware and software modules used in KOMPSAT-1 satellite program if possible. Thernobjective of EGSE is to provide hardware and software for efficient electrical testing of integrated KOMPSAT-2rnsatellite in three general categories. (1) Simulators for ground testing (e.g. solar–simulation power, earth scenes,rnhorizons and sun sensor). (2) Ground station type satellite data acquisition and processing test sets. (3) OverallrnControl of Satellite using Hardline datum.rnIn KOMPSAT (Korea Multi-Purpose SATellite) program, KOMPSAT-2 EGSE was developed to supportrnsatellite integration and test activities. The KOMPSAT-2 EGSE was designed in parallel with satellite design.rnConsequently, the KOMPSAT-2 EGSE was based on the KOMPSAT-1 heritage since the spacecraft designrnfollowed the heritage. I.e) The KOMPSAT-2 baseline was elaborated by taking advantage of experience fromrnKOMPSAT-1 program. The EGSE of KOMPSAT-2 design concept is generic modular design with preference inrnpart selection with commercial off-the-shelf which were proven from KOMPSAT-1 programs, flexible/user friendlyrnoperational environment (graphical interface preferred), minimized new design and self test capability.
