Abstract: The present invention relates to an apparatus and a method for simulating a satellite mission operating state. The apparatus, according to the present invention, comprises: a satellite operation procedure rule definition unit for registering a satellite operation procedure rule which defines a satellite operation procedure keyword and attribute corresponding to a satellite's state of performing a mission of interest; a satellite operation procedure processing unit for receiving a satellite operation procedure which includes a series of operation procedures prepared for the satellite to perform the mission, and extracting, from the received satellite operation procedure, a keyword and attribute value corresponding to the keyword and attribute included in the registered satellite operation procedure rule a mission list storage unit for storing a list of mission performance actions arranged in the order of execution time, wherein the mission performance actions correspond to the extracted keyword and attribute value; an orbit data storage unit for storing orbit data of the satellite; a time management unit for providing a current time; and a control unit for confirming an orbit and the mission performance action corresponding to the current time from the orbit data of the satellite and the mission list, and causing the satellite's state of performing the mission of interest to be visually displayed.

Abstract: The present invention relates to a conjunction summary message (CSM)-based analysis system for a collision that includes space debris which moves in space, a user satellite which is operated by a user, a joint space operations center server which receives information collected through a space debris monitoring satellite and radar or an optical camera and calculates orbit information and covariance information about the user satellite and the space debris, and a collision risk analysis server which analyzes a collision risk between the satellite and the space debris based on the orbit information and the covariance information calculated by the joint space operations center server, thereby having effects on improving precise prediction of collision between the satellite and the space debris based on a CSM informing the collision risk between the satellite and the space debris while operating a global space monitoring network, and significantly reducing a total time taken in determining and analyzing a precise orbit of the space debris and making an optimized collision-avoidance maneuver plan, through the effective user interface and system.
