Leader: LVNL


The main aim of this Implementation Project is to upgrade the Advanced Surface Movement Guidance and Control System (A-SMGCS) surveillance system at Schiphol Airport to provide the high performance surveillance information required by (is a pre-requisite for) A-SMGCS routing & planning functions and airport safety nets. The A-SMGCS routing & planning functions and airport safety nets require full coverage of the Runways and Airfield Surface Movement area including the gate areas (for detection of push-backs) and a high availability of the surveillance information. The full coverage requires optimal sensor locations to guarantee detection by surveillance sensors and to improve the quality of the surveillance data. The high availability requires a redundant design for the communication between sensors and central processing units and redundant central processing Ground Surveillance units. The high availability of the new system prevents disturbing outages at Schiphol thus improving resilience. The A-SMGCS surveillance system provides its information to the Air Traffic Control Tower system in which further processing takes place for various functions. These Tower system function are not in the scope of the Implementation Project.
A state of the art tower system (flight processing system), that is also a prerequisite for A-SMGCS Routing and Planning Functions, is realised by the implementation project 2015_187_AF2 ""TWR System at Amsterdam Schiphol"". In this tower system project, the last part of the data processing chain needed for A-SMGCS level 1&2 will be realised according to the PCP requirements (Family 2.2.1). The first part of the chain consists of the A-SMGCS surveillance system. In a future CEF call LVNL will propose the activities for adding A-SMGCS Routing and Planning Functions to the tower system. There are no overlaps between the proposed implementation project and the implementation projects 2015_187_AF2 ""TWR System at Amsterdam Schiphol"" and 2016_150_AF2 _GND ""Enabler for Surface Movement & Safety Nets"". These implementation projects have a clearly separated scope and complement each other. Flexible routing by means of individual lamp control in the manoeuvring area requires route information provided by the tower system. The tower system will use A-SMGCS surveillance information and the A-SMGCS Routing and Planning Functions for the Airport safety nets function.

Specific objectives:
The A-SMGCS surveillance system specifically aims to use co-operative airport surveillance sensors at Schiphol which provide both Multi LATeration (MLAT) and Automatic Dependent Surveillance Broadcast (ADS-B) updates. MLAT uses Time Difference Of Arrival (TDOA) measurements to determine the position of transponder equipped aircraft and vehicles. ADS-B forwards the position measured on board of the aircraft or vehicle (usually a GPS position). The implementation project ensures optimal A-SMGCS surveillance coverage at Schiphol Airport by the right number of sensors and optimal sensor locations, installing state of the art sensors which support multiple central surveillance processing systems. The sensor locations are selected in consultation with Amsterdam Airport Schiphol. The installation of additional antennas and communication cables is carried out in good cooperation with Schiphol Airport. High availability of the sensor information is guaranteed by using a redundant data communication infrastructure, and a redundant central surveillance processing system. Then sufficient quality of surveillance data can be obtained for further A-SMGCS processing and use by the tower system.

Expected Results:

  • The optimal coverage of the airport with an optimal number and location of the Ground Surveillance sensors is defined.

  • An improved (redundant) communication infrastructure between sensors and central units is deployed.

  • New surveillance sensors are installed at optimal locations at Schiphol Airport to provide optimal coverage of the airfield.

  • Sensors can be controlled by multiple central units.

  • The central surveillance processing system is upgraded to a redundant system. A second central surveillance processing system is installed (which shares the ground surveillance sensors with the present central surveillance processing system).

  • The upgraded A-SMGCS Surveillance System at Schiphol airport is deployed including validation of the system.

  • New & optimised back-up procedures to improve availability in outage situations are deployed.

  • Technical and operational personnel are trained for the system.

  • Transition of the system into operation is ensured.

  • The system is handed-over to the change and maintenance organisation.

Performance Benefits:
The implementation project improves the ability to withstand and recover from low visibility conditions which cause a loss of nominal capacity. The deployment of the A-SMGCS Surveillance System improves the quality of surveillance data by a better coverage of the Schiphol Airport area and sensor redundancy. The loss of air traffic situation picture in limited visibility conditions is very unlikely but the resilience is improved. Scheduled downtime – related to maintenance and central surveillance processing system upgrades – are being minimised by adding a second central processing system. A second central system allows LVNL to execute maintenance and test activities during regular office hours (thus enabling more effective use of human resources).
A-SMGCS is required for providing aerodrome surveillance as well as planning, routing and guidance for the control of aircraft and vehicles in order to maintain the declared surface movement rate under all weather conditions within the aerodrome visibility operational level (AVOL) while maintaining the required level of safety. The deployment of a high performance A-SMGCS surveillance system at Schiphol Airport is a prerequisite and critical enabler to deploy additional performance improvements (on safety, capacity and predictability) that can be obtained by implementing routing & planning functions and airport safety nets in the Air Traffic Control Tower system."
