Abstract:
The present invention relates to an electromagnetic wave jamming technology and, more particularly, to a global positioning system (GPS) jamming alert system and a method thereof which continuously generate a jamming alert by determining a signal as a GPS jamming attack if the signal exceeds a predetermined range of message validity, a message update rate, a standard error, and a maximum movable range by the maximum velocity, and improves the reliability of determination for GPS jamming according to the number of continuous generations. According to the present invention, an operator can always identify the validity of location and/or time information provided from the GPS, take an action according to the events, and perform tasks without interruptions by immediately generating a GPS jamming alert by receiving and analyzing location and time information provided from the GPS when a GPS jamming event occurs.

연동 장비의 운용 상태를 통합 관리하기 위한 함정 전투 시스템 및 그 방법이 개시된다. 연동 장비의 운용 상태를 감지하여 생성한 운용 상태 감지 정보를 송신하는 연동 노드와, 상기 운용 상태 감지 정보를 수신하고, 수신된 운용 상태 감지 정보를 이용하여 상기 연동 노드의 운용 상태 정보를 가용 상태 또는 비가용 상태로 설정 또는 변경하고, 상기 설정 또는 변경된 운용 상태 정보를 각 연동 노드별로 통합 표시하는 통합 관리 노드를 포함하는 연동 장비의 운용 상태를 통합 관리하기 위한 함정 전투 시스템을 구성한다. 상기와 같은 연동 장비의 운용 상태를 통합 관리하기 위한 함정 전투 시스템 및 그 방법에 의하면, 지휘 노드에서 지휘자가 각 연동 노드의 동작 상태를 한 눈에 파악할 수 있는 효과가 있다. 그리고 연동 노드에서 동작 오류가 발생할 시에는 어떠한 종류의 동작 오류가 발생했는지도 파악할 수 있는 효과가 있다. 함정, 노드, 통합 관리, 연동, 모듈, 운용 상태, 하트비트
Abstract:
PURPOSE: A device and a method for searching a still path performing data distribution service in a ship battling system, and a computer readable medium recording a program performing the same are provided to reduce an error of a main memory device and time for searching a path and increase availability of a main memory device of each node by searching a path based on an individual file included in a DDS object related to an application program. CONSTITUTION: An individual discovery file generating unit(210) generates an individual searching file which includes the collected DDS object. An individual discovery file storing unit(220) stores the individual file. A still path searching unit(230) searches still path by suing the stored individual search file.
Abstract:
PURPOSE: Battle system and method of managing the operation states of linked facilities are provided to enable the kind of operating errors to be recognized if an operating error occurs on a linked node. CONSTITUTION: A battle system for managing the operation states of linked facilities comprises a linked node(200) and a managing node(300). The linked node transmits operating-state sensing information, which is generated by the sensing of the operating state of a linked facility. The managing node receives the operating-state sensing information. The managing node sets or changes the operating state information of the linked node to an available state or an unavailable state using the received operating-state sensing information. The managing node displays the set or changed operating state information by each linked node. The managing node set or changes the operating state information to an unavailable state if each operating-state sensing information of the multi board of the linked facility is in an unavailable state.
