Source: (EUROCONTROL SDDS Website ) RMCDE (SuRveillance Message Conversion and Distribution Equipment〔(【引用サイトリンク】url=http://www.eurocontrol.int/services/surveillance-message-conversion-and-distribution-equipment-rmcde )〕) is the name of a system designed to distribute the surveillance information to a community of user systems. A user of surveillance data in a general sense is defined in this context as any Air Traffic Control (ATC) subsystem having a requirement to receive at defined instants the best and most up-to-date position information for all air traffic of interest to this user (e.g. Operator Display System, Flight Data Processing System, ATC Tools, Flow-Control Management Units, Remote Terminal Maneuvering Area's, Military Units, etc.). The data can be originating from a surveillance sensor (e.g. radar, ADS-B receiver, Multi-lateration system) or a surveillance data processing system (e.g. ARTAS) RMCDE is a Multibus II based multiprocessor system composed of a number of subsystems (processor and IO boards) connected through a parallel data bus. In addition to its distribution function, the RMCDE offers additional capabilities to manage the surveillance data flow like data validation, conversion and filtering. ==RMCDE History== Until 1990, each ATC centre was serviced by a dedicated set of (local) radars. Radar data exchange was only done at a limited scale, one of the reasons being that the sensors were using proprietary, incompatible formats. An exception to this practice is the Eurocontrol Maastricht Upper Area Control Centre (MUAC). Designed from the beginning as an international centre handling only en-route traffic, it does not have its own sensors since the MUAC airspace was already sufficiently covered by the sensors of the 4 participating states (Belgium, Netherlands, Luxembourg and Germany). In April 1990, the Ministers of Transport of the European Civil Aviation Conference (ECAC) launched the "En-route Strategy for the 1990's" - a multilateral strategy designed to ensure that, by the end of the century, Air Traffic Control capacity will match forecasted demand. This strategy drove an initial programme, EATCHIP - the European ATC Harmonisation and Integration Programme, developed and managed by Eurocontrol to undertake the progressive harmonisation and integration of Air Traffic Services throughout the ECAC area. One of the key pointpoints in this strategy was to harmonise the data formats used in ATC data exchange. The format chosen for surveillance data was ASTERIX (All Purpose Structured Eurocontrol SuRveillance Information Exchange). The combination of harmonisation, MUAC data needs and the emergence of computer network technology led the way to the development of a X.25 based surveillance data distribution network:〔(EUROCONTROL Surveillance Data Distribution System Information )〕 RADNET. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RMCDE」の詳細全文を読む スポンサード リンク
