- An integrated Mission Analysis and Planning System (MAPS) has been developed for the KOMPSAT-2 mission operations. MAPS provides the satellite mission analysis functions such as orbit determination, orbit prediction, orbit maneuver, fuel accounting, and antenna pointing data generation. MAPS also provides the satellite mission planning functions including event prediction, mission scheduling, command planning, and ground track display. Ground based antenna tracking and ranging data will be used for the orbit determination during Launch and Early Orbit Phase (LEOP) operations. GPS based orbit determination will be used when the GPS receiver on-board the satellite is switched on. Two types of orbit determination will be performed for the satellite using GPS data. One is the operational orbit determination using GPS navigation solutions and the other is the precision orbit determination using GPS raw measurement data for the position accuracy of 1 meter. Orbit maneuver planning generates in-plane and out-of-plane maneuver parameters for maintaining the orbit. Integrated event prediction functions including satellite orbital events, user requested imaging events, and satellite operational events have been implemented. Mission scheduling functions have been realized to detect the mission conflicts considering the user specified constraints and resources. A conflict free mission scheduling result is mapped into the spacecraft command sequences in the command planning functions. The command sequences are directly linked to the spacecraft operations using eXtensible Markup Language (XML) for command transmission. Ground track display shows the satellite ground trace and mission activities on a digitized world map with zoom capability. In this paper, design, implementation, and test of the integrated Mission Analysis and Planning System for the KOMPSAT-2 Mission Operations are presented. An Object Oriented Design (OOD) approach is used for the process of system analysis and design. System analysis is composed of Use-Case Model and Domain Model. System design consists of User Interface Design and Architecture Design. Logical View, Implementation View, Process View, and Deployment View are the four views of the architecture design. © 2006 by the American Institute of Aeronautics and Astronautics, Inc.
