- Abstract
- ROS (Real-time Operations Subsystem) is main subsystem of SGCS (Satellite Ground Control System) for COMS (Communication, Ocean and Meteorological Satellite). The ROS performs reception and processing of telemetry data from COMS, planning and transmission of telecommand to COMS via S-band link. ROS supports satellite simulation using DSSS (Dynamic Satellite Simulator System) and CSS (COMS Simulator Subsystem), dwell telemetry management in case of satellite anomaly state, dump telemetry management for analyzing satellite status, ancillary telemetry transmission to MSC (Meteorological Satellite Center), KOSC (Korea Ocean Satellite Center) and IDACS (Image Data Acquisition and Control System) in SOC (Satellite Operation Center) periodically for image processing, operation procedure support by converting FOP (Flight Operation Procedure) delivered from Astrium into operation procedure for ROS and executing using command executor, telecommand authentication for satellite authentication. We designed ROS as UML (Unified Modeling Language) which includes use case modeling, domain modeling and also includes package design, component design, process design and deployment design. In this paper we will show the modeling and design of these ROS in detail. © 2007 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.
