Abstract: A drone swarm control method is provided. The drone swarm control method includes displaying a drone swarm and a three-dimensional (3D) terrain projected onto a virtual reality (VR) space by using a VR headset, based on user manipulation, selecting a small-scale drone swarm, provided in a region of interest (ROI) set in the 3D terrain, from the drone swarm by using a VR controller, based on the user manipulation, and dividing, by using a server, the ROI into a plurality of cells, respectively allocating the divided plurality of cells to drones included in the small-scale drone swarm, and automatically generating a 3D flight path of a drone allocated to each of the divided plurality of cells, based on user input information representing the small-scale drone swarm and the ROI.

Abstract: The present disclosure provides a communication device which is suitable for use in an unmanned aerial vehicle operating in an unmanned aerial vehicle collaboration system including multiple unmanned aerial vehicles and enables both a data communication with another unmanned aerial vehicle and a measurement of a distance to another unmanned aerial vehicle. According to an aspect of an exemplary embodiment, a communication device of an unmanned aerial vehicle includes: an ultra-wideband (UWB) communication circuit configured to perform a UWB communication with other unmanned aerial vehicle; and a UWB communication manager configured to send transmit data to the other unmanned aerial vehicle and receive data sent by the other unmanned aerial vehicle through the UWB communication circuit, and transmit or receive shared data to be shared by unmanned aerial vehicles in a form of being appended to a distance measurement frame.

Abstract: Disclosed is a UAV quality certification system. The UAV quality certification system according to an embodiment of the present disclosure may include: a virtual UAV configuring unit determining information on hardware devices included in a UAV, and configuring a virtual UAV; a UAV simulator performing simulation for the virtual UAV; a UAV flight learning unit controlling learning for a UAV flight learning model that receives the information on hardware devices included in the UAV as an input, and outputs a result of the simulation; and a quality evaluation unit performing quality evaluation on at least one target included in the UAV by using the UAV flight learning model.

Abstract: A method of randomizing a size of a packet is provided. A randomization method may include recognizing a maximum segment size (MSS) defined for transmission and reception of a packet with a reception terminal, and randomizing a size of the packet to be less than the MSS.

Abstract: Provided is a task processing apparatus and method that may select a task corresponding to predetermined task selection information when a task execution is completed and thus, an idle server occurs in at least one server, may separate the selected task into a first task and a second task, and may control the first task and the second task to be allocated to an existing allocation server of the selected task and an idle server, respectively.

Abstract: A flight dynamics subsystem (FDS), a velocity increment calculation module, and operational methods of the same are provided. A used fuel quantity actually used in a satellite is calculated, and a velocity increment is calculated using the calculated fuel quantity. Therefore, an orbit of the satellite may be estimated more accurately.

Abstract: Provided are an apparatus and a method that differently sets the access authority of a user for individual parts of an online document. For every parts of the online document, the user authority is set and the parts are edited only by a user that can access the part. Finally, the parts of the documents are combined as the final document. According to the present invention, the document is divided into parts and the access authority of the user is variously set, which results in maximizing the efficiency of editing the document. The editors of the individual parts inherit the authorities to other people, so that it is very efficient for the cooperative job of a document in the organization having a hierarchy.

Abstract: Provided is a cloud computing service providing system that may generate a list by classifying at least one information providing terminal based on platform information and content information received from the at least one information providing terminal, may provide the generated list to at least one user terminal, and, when a selection signal indicating that one of the at least one information providing terminal is selected by a user terminal, may connect the user terminal with the selected information providing terminal based on a peer-to-peer (P2P) scheme.

Abstract: Provided is a method for transmitting a file based on a multiplex forwarder using a session join time interval. The method includes the steps of: a) transmitting a session join request message to a source and joining to a corresponding session; b) when a member joins the session, transmitting a forwarder candidate list request message to the source and receiving a forwarder candidate list; c) skipping a specific member among members on the transmitted forwarder candidate list; and d) transmitting a forwarder request message to the members on the forwarder candidate list excluding the specific member, selecting a member permitting the request as a forwarder, and receiving a gift, which is a packet, from the selected forwarder.

Abstract: Provided is a mission scheduling method. The mission scheduling method includes: when a time window representing a time range that a plurality of missions are executed and a duration of the missions are given, determining an execution start time and finish time of each of the missions; selecting a first mission that is first finished among the missions; selecting second missions which collide or do not collide with the first mission depending on the execution order of the second missions; and including in a schedule a mission that is first finished when the first mission and the second missions are respectively executed according to a combination of orders, wherein the first mission and the second missions according to the combination of orders do not collide with each other.
