What is an Aircraft Detection Lighting System?

Wind turbines are equipped with obstruction lights to be visible in the dark for air traffic. Those obstruction lights blink from dusk till dawn, no matter if an aircraft is nearby or not. This constant blinking has proven to be an obstacle in the acceptance of wind power.

To stop the unnecessary blinking and to make the night sky dark again, there is a technology called Aircraft Detection Lighting System, ADLS for short.

Through ADLS, it is possible to turn off the blinking obstruction lights of wind farms. This is done by monitoring the airspace around a windfarm and only giving an activation signal towards the obstruction lights once an aircraft is in near vicinity.

The light:guard Aircraft Detection Lighting System

Transponder

Every flying object is obligated to send out transponder signals to be identifiable. Those are being received by the Light:Guard receivers.

Multilateration

The system receives continuous data from all receivers at once and is therefore able to achieve a higher network coverage than each individual receiver would by itself.

Accuracy

This leads to a better signal quality and higher light-off times for each wind turbine, especially in areas with high air traffic or large wind farms.

How it works:

  • Aircraft transmits transponder signals
  • Signals are received by the Light:Guard receivers (LGRs) distributed throughout the country
  • LGRs transmit the signals to the Light:Guard data center where the location and trajectory of the flying object are calculated using multilateration
  • Data center communicates continuously with the Light Control Unit (LCU-T) in the wind farm, which controls the lights
  • No flying object within 6 km range → lighting is suppressed, the light is off
  • Flying object within 6 km range → suppression is lifted, the light is on

Key Advantages

  • High expertise and professionalism due to already existing experience through radar-based ADLS
  • High integration intelligence with all manufacturers due to long-standing competence in the aviation lights business
  • High signal quality through connectivity of all receivers and multilateration approach
  • High scalability through central communication
  • High error safety due to technically closed and redundant system
  • No infringement of patents due to own design
Headline: Aircraft Detection Lighting System (ADLS) with the light:guard system. A helicopter transmits transponder signals to receivers (LGR) on wind turbines, which forward these signals to the data center (MLAT and QUAD), where they then calculate the helicopter's location using multilateration and forward ADLS signals to the wind farm to cancel the suppression of the light when the helicopter is near the wind farm.
