Abstract: PURPOSE: A system for extracting and predicting initial data for a satellite simulator is provided to estimate the state of a satellite in the ground when an abnormality of the satellite is generated and generate a proper restoration procedure, thereby restoring the satellite. CONSTITUTION: A receiving unit(310) receives initial satellite state data and initial flight dynamic data. A data extracting device(320) extracts satellite state data and flight dynamic data from the initial satellite state data and the initial flight dynamic data. A data estimating device(330) predicts satellite state data and flight dynamic data of a future time point from the satellite state data and the flight dynamic data. The data estimating device includes a filter(335) and a dynamic model unit(336) connected to the filter. The initial satellite state data is received from a real-time operating system of a ground control system.

Abstract: PURPOSE: A NORAD TLE(North American Aerospace Defense Command Two-line Elements) data-based orbit determination system and a method thereof are provided to obtain high precision of position information by utilizing NORAD TLE data receiving from a JSPOC(Joint Space Operations Center) as pseudo measurement data. CONSTITUTION: A NORAD TLE data-based orbit determination system comprises a TLE preprocessing part(100), an orbit determining part(200), and a position information output part(300). The TLE preprocessing part propagates NORAD data to an SGP-based orbit propagator to obtain position data on an ECI(Earth-Centered Inertial) coordinate system; converts the position data on the ECI coordinate system to position data on an ECEF(Earth-Centered-Earth-Fixed) coordinate system; and converts the converted position data on the EDEF coordinate system to PCE format position data. The orbit determining part determines information on the position of an orbit determining target through a batch processing technique by using the PCE format position data as pseudo measurement data. The position information output part converts the information on the position of the orbit determining target to a preset data format and outputs the data.

Abstract: A hingeless rotor apparatus having stacked type flexures is provided to reduce a manufacturing cost by acquiring stability through a coupling stiffness without an additional apparatus such as a lead-lad damper. A hingeless rotor apparatus having stacked type flexures includes a rotor shaft connection unit(110), a plurality of blades(300), and a plurality of flexures. The plurality of blades are rotated by the rotor shaft connection unit. An end of the plurality of flexures is connected to a hub, and the other end of the plurality of flexures is connected to the blade. The flexures are stacked by a plurality of free flag layers having reinforced fiber and material. Any one of the plurality of composite material layers has a differently arranged reinforced fiber from a reinforced fiber length direction of the different layer.
