1 Oslo Airport Gardermoen Advanced Surface Movement Guidance and (A-SMGCS)

2 The Project: Advanced Surface Movement Guidance and Safe and efficient ground movements in all weathers, this was the main objective in the design of the new Oslo Airport Gardermoen. So the decision was to combine the Surface Movement Surveillance and the Airfield Lighting in order to procure an Advanced Surface Movement Guidance and. The main goal of the A-SMGCS is to provide visual guidance to pilots on the ground and surveillance facilities to air traffic controllers including automatic presentation of taxiroutes, alert functions, aircraft and vehicle detection and tracking. The project has been awarded to the Consortium formed by and under leadership of ADB. Airport Layout: Runways, taxiways and apron with airfield lighting Substations Surveillance movement radar Tower and tower control building Terminal building 1

3 Scope of supply for A-SMGCS Airfield lighting control system Project Details Surface movement surveillance system Consortium Oslo Airport Gardermoen The contract was awarded to the consortium of ADB, CARDION, HITT and Siemens AS where: ADB, as consortium leader, was reponsible for project management, has designed the taxiway guidance system and provided the airfield lighting control system and the individual lamp control and monitoring system, Brite II. Cardion, a Siemens Company designed and delivered the ground radar systems. The contract The content of the project was integration of an Airfield Lighting with a Surface Movement Surveillance to deliver the world s first A-SMGCS. This A-SMGCS provides seamless surveillance of ground traffic under all weather conditions including track and labelling functionalities for the ATC, a visual guidance to pilots with automatic calculation of taxiroutes and alert functions (e.g. for the unauthorized crossing of stop bars). The customer OSL, a company established by the Norwegian Civil Administration to plan, build and operate the new Oslo Airport Gardermoen. The A-SMGCS display The new Oslo Airport Gardermoen has two parallel runways and an initial capacity of million passengers, meeting a demand of 12 million in 2000 and incorporating the flexibility to continually expand in response to an estimated annualized growth of 3-4 % over the next 20 years.the airport layout allows up to 80 movements an hour. HITT, Hollands Institute for Traffic Technology, provided digitalized radar data providing tracks and labels, the multi sensor fusion, the central data processing system and developed the human interface for the ground movement traffic controllers. Siemens AS, Oslo, was responsible for the installation and delivery of radar cabins, tower and radomes. Contractual time schedule After a three months evaluation of the tenders, the contract for the A-SMGCS system was awarded in December 1995 to the consortium. The system was designed, built, installed and taken into operation in 30 months. The new Oslo Airport Gardermoen opened in October

6 A-SMGCS description The A-SMGCS combines two well known technologies, the airfield lighting control system and surface movement surveillance. Surveillance system Two surface movement radars provide full-coverage of the manoeuvring area. Aircraft and vehicles are detected and tracked under all weather conditions. The data processing system receives aircraft identification from the flight plans with additional data from the approach radar, the gate management system and the docking system. It generates tracks and provides labelling information to display the call sign, with aircraft type and allocated gate or runway on the Integrated Workstation. ATC ler Presentation Maintenance Personnel Radar Video Surface Movement Radar Sensors (SMRS) Airfield Lighting All airfield lighting fixtures are individually controlled and monitored by the Brite II system. The entire taxiways are equipped with centre line lights, intermediate intersection bars, stop bars and signs. The taxiway centre line lights are grouped into segments. The status of each segment is continuously provided at the Integrated ler Workstation (ICW) and the ALCS service. Maintenance Commands Status & Monitoring Data Flight Data Processing (ICW FDPS) Selection Status Flight Data Central Technical Management (CTMS) SMSDP and SMGCS ALCS Status Radar Data Processing (ICW RDPS) ALCS ALCS TAR Data By means of Brite II, taxiway centre line lights, stop bars and signs are indivually controlled, to provide continuous guidance to pilots. All lights are permanently monitored and the system generates alarms if two consecutive taxiway lamps are burnt. The number of taxiways centre line lights are switched on depending on the weather conditions and mode of operation meeting the ICAO recommendations for CAT.I or CAT. II/III operation. GMS: Ident. Gate Lead-in Light Lead-in Light Status Integrated ler Workstation (ICW) Operational Configuration Data Gate Management (GMS) Central Docking (CDCS) Data, Time Network Time Reference (NTRS) SMGCS display The Surface Movement Guidance and display presents the actual traffic situation together with the status of the visual aids required for ground movement of aircraft and airport vehicles on the airport manoeuvring area. The traffic situation is presented by showing simultaneously radar and synthetic data (tracks, maps, taxiway status, etc ). The display allows presentations of data in multiple windows, to combine a general traffic overview with a detailed view on a specific area of the airfield that requires special attention. Multiple windowing also allows simultaneous presentation of traffic situations and performing a more efficient management of the ground movements and possible maintenance activities. Selection may be performed by user-friendly drop-down menus, buttons and scrollable lists. The design is modular and in combination with the use of proven standards, results in an easily adaptable, expandable, maintainable and userfriendly display system. 5 The following diagram depicts the context of the Surface Movement Surveillance Data Processing (SMSDP) and Surface Movement Guidance and (SMGCS).

7 Summary A-SMGCS function Routing Based on information of gate number, aircraft position and runway, the system suggests a taxiroute which is presented to the air traffic controller on his display. Once accepted by the air traffic controller, all segments forming the desired route will be switched ON by the Airfield Lighting using the Brite II system to control the required taxiway lights. It also provides status feedback of each segment, presented on the display of the air traffic controller and ALCS services terminals. Guidance On the taxiway and manoeuvring area, taxiway centre line lights, signs and stop bar lights are used to provide the pilot with continuous guidance on his route from the gate to the runway and vice versa. For the final approach of the aircraft to the terminal, the docking systems sends a message to the Airfield Lighting to switch on the leadin lights in order to indicate the selected gate to the pilot. Stop bar control: The surface movement radar detects and tracks each aircraft. After an aircraft has passed a stop bar, it is switched on again automatically using the aircraft s position data from the surface movement radar. Brite II enables individual control of the stop bar lights. Stop bar lights will be lit automatically according to t he (weather dependant) mode of operation. Conflict alert: Based on the information from the surface movement radar, the system calculates whether an aircraft or vehicle has crossed an active stop bar, penetrated a runway area or a runway in use, or entered a closed area. Occurrence of these dangerous situations will generate an audible and visual alarm on the Integrated ler Workstation to alert the air traffic controller. Efficiency Thanks to the innovative taxiway guidance system, continuous ground traffic is guaranteed under all weather conditions, while the down time of a taxiway for maintenance of the AGL is reduced. This allows the airport to keep up a high rate of take off s and landings. ALCS display For the first time ever a surface movement radar and an airfield lighting system have been integrated to provide an Advanced Surface Movement Guidance and (A-SMGCS). This innovative system increases safety by reducing potential risks of ground collisions at Oslo Airport Gardermoen as well as increasing efficieny and is prepared for future growth.
