ARTAS (ATM suRveillance Tracker And Server) is a system designed by Eurocontrol in order to help in Aerial surveillance and Air traffic control. It can establish an accurate Air Situation Picture of all traffic over a well-defined geographical area (e.g. ECAC), and to distribute the relevant surveillance information to a community of user systems. ARTAS users A User of ARTAS in a general sense is defined in this context as any ATC subsystem having a requirement to receive at defined instants the best and most up-to-date estimate of all or selected aircraft state vector elements for all air traffic of interest to this User, e.g.: *Operator Display System, *Flight Data Processing System, *ATC Tools, *Flow-Control Management System, *Sequencing and Metering system, *Remote TMA’s, *Military Units, etc. ARTAS is a distributed system composed of a number of identical subsystems co-operating together. Each subsystem, called an ARTAS Unit, will process all radar data reports to form a best estimate of the current Air Traffic situation within a given Domain of Interest. Adjacent ARTAS Units will co-ordinate their tracks to build a unique, coherent and continuous Air Situation Picture over the complete area. ARTAS unit groups Four groups of main functions are implemented in an ARTAS Unit: *The TRACKER processes the radar input data and maintain the latest air situation represented in the Track Data Base. *The SERVER carries out the Track and Sensor Information Services, i.e. the management of all requests from Users and the transmission of the relevant sets of track/sensor data to these Users, and the so-called inter-ARTAS co-operation functions *The ROUTER BRIDGE handles the external interfaces to the Normal Users, the Broadcast Users, the Adjacent ARTAS Units and the surveillance sensors. It also implements the Radar Input Processing function. *The SYSTEM MANAGER carries out the functions related to the supervision and management of the ARTAS Unit. == ARTAS History == 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 forecast demand. EATCHIP: 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. EATMP: A programme has been established to provide the framework for meeting the objective of the ATM 2000+ Strategy, EATMP – the European Air Traffic Management Programme, as a follow-up of EATCHIP. The overall objective of the current “ATM 2000+ Strategy” is to enable the safe, economic, expeditious and orderly flow of traffic through the provision of ATM services which are adaptable to the requirements of all users and areas of European airspace for all phases of flight. These services are to accommodate demand, be globally inter-operable, operate to uniform principles, be environmentally sustainable and satisfy national security requirements. In the context of EATCHIP and the continuing EATMP, it has been proposed that a progressive integration of European Surveillance Data Processing Systems (SDPS) be introduced with the aim to: * make use of advanced tracking techniques, * eliminate the known shortcomings of tracking systems, * allow an efficient service to a large variety of user system of processed surveillance information, * and allow a seamless integrated operation in a mutli-centre environment across Europe. Launch of ARTAS With this aim, the development of a prototype ATM suRveillance Tracker And Server (ARTAS) was undertaken which would function as a Pilot System for the systems to be implemented in forthcoming decade by EUROCONTROL Member and other ECAC States The phased development of ARTAS started in June 1993. In parallel to the development, a comprehensive evaluation programme of the successive versions of the ARTAS Pilot system has been undertaken with a number of National ATM Organisations. Following the evaluation programmes, ARTAS has been gradually introduced as operational system and it is part of the surveillance infrastructure of numerous operational centres of Europe. It is believed that such an implementation of a harmonised Surveillance Data Processing System like ARTAS, together with the wide introduction of Radar Data Networks and the improvements of radar sensors created the necessary technical condition for improved ATM co-ordination and the uniform application of radar separation minima throughout a large part of Europe. In addition to the ARTAS system, a Central ARTAS software Maintenance and Operational Support (CAMOS) service for those versions of ARTAS that are in pre-operational or operational use was created. CAMOS collects the ARTAS system data and parameters needed to ensure the exchanges of surveillance data between the States implementing ARTAS and provides software enhancements to the commonly developed ARTAS System for functionality required by changes in the technical environment or common user needs Further evolution of the ARTAS system is taking place following Users requests, requests from Surveillance related Programme or due to technological advances Considerable savings are realised because of the large scale implementation of ARTAS. These benefits are due to the use of a common development and support structure instead of many independent structures.
