Abstract: A safe landing point search device for searching for a safe landing point of an unmanned exploration device that lands on and explores a celestial body, includes a terrain map obtaining unit configured to obtain a terrain map, a contour line generating unit configured to generate contour lines based on a reference minimum height value and a height interval value by using the terrain map, a largest empty circle (LEC) searching unit configured to search for one or more LECs having a radius greater than or equal to a lower-limit radius in a contour line map including the contour lines, and a safe landing point outputting unit configured to output a safe landing point having a largest radius among the one or more LECs and transmit the safe landing point to the unmanned exploration device.

Abstract: Disclosed is a metaverse platform operating method and system for implementing a virtual universe space. The metaverse platform operating method includes: obtaining a plurality of satellite data from a satellite vehicle on a predetermined period for a predetermined time; constructing space situational awareness (SSA) information associated with the satellite vehicle by processing the plurality of satellite data; generating a metaverse-based virtual universe space in which the satellite vehicle is positioned for the predetermined time, through three-dimensional (3D) modeling of the SSA information; at an access request from a device, identifying a satellite-related organization to which the device belongs, using a login account included in the access request; and visualizing the metaverse-based virtual universe space on the device according to an information access right of the satellite-related organization.
