ADB SAFEGATE Gothenburg Landvetter

Gothenburg-Landvetter Airport in Sweden was one of the very first airports to use individual control and monitoring of airfield lighting. Their very first system is still in operation but has over the years gradually been extended to include all airfield lighting at the airport: taxiway, stop bars and sensor systems.

The first system at Gothenburg-Landvetter included taxiway systems, stop bars, lead-on segments, runway guard lights, lead-in lights at gates and so on. There are also vehicle traffic lights and CAT II signs connected to and controlled through these ASP-SafeControl system circuits. Most of the taxiway lights are inset lights with two individually controllable lamps and about 2200 lamps in this system.

Additional systems in 2000
In year 2000 Gothenburg-Landvetter changed the power supply system for the runway, approach and PAPI from parallel to series supply. During this process they also installed ASP-SafeControl to control and monitoring these functions. A unique ASP-SafeControl function is also used to make it easier for the CCRs when switching large light segments on and off. As long as there is current in the circuit, the ASP-SafeControl system also monitos the lamp, even if the light has been switched off. Nearly 1300 lights are connected to this system.

New systems in 2005
During 2004 and 2005 the airport changed the existing power supply system from parallel to series supply for the remaining taxiways, stop bars, lead-on, runway guard lights, lead-in and so on. At the same time the existing individual control and monitoring system, as previously described was replaced with the ASP-SafeControl system for series circuits. In total there are about 3400 lamps individually monitored and controlled with more sensors to be added. The complete new system was installed in one substation in contrast to the existing system that was installed in five different substations.

ASP-SafeControl interface to other systems
At Gothenburg-Landvetter the ASP-SafeControl system is being integrated to the airport’s existing control system. It also gives information about the stop bars to the airports radar system. This and other types of interface solutions can be supplied to meet customers’ requirements or for integration into an ASP-SafeControl system.

Over 20 years of experience
Since the very first installation of ASP-SafeControl in1989, about 100 ASP-SafeControl systems have been delivered to airports in Europe, Asia and the US. Most of these systems have been installed into existing circuits. This enables  ADB SAFEGATE engineers to continuously develop a robust and flexible ASP-SafeControl system. For example, ASP-SafeControl is able to handle different CCR and transformer types from different manufacturers as well as systems with screened or non-screened cables, whilst still providing reliable operation. The commissioning process is also continuously developed in order to minimise the time for implementing ASP-SafeControl into an existing system, as airports are often in full operation.

ADB SAFEGATE is a leading provider of intelligent solutions that deliver superior airport performance from approach to departure. The company partners with airports and airlines to analyze their current setup and operations, identify bottlenecks, and jointly solve them using a consultative approach that enables airports to improve efficiency, enhance safety and environmental sustainability, and reduce operational costs. Our integrated portfolio includes solutions and services that harmonize airport performance, tackling every aspect of traffic handling and guidance, from approach, runway and taxiway lighting, to tower-based traffic control systems, and intelligent gate and docking automation. ADB SAFEGATE has more than 900 employees in more than 20 countries and operates in more than 175 countries, serving more than 2,000 airports.
