About us

In 2014, ENERTRAG Systemtechnik received permission from German Authorities for its ADLS-system “airspex”. In 2015, they launched the Langenhorn project as Germany's first ADLS project following the publication of the original legal framework. Later, airspex GmbH was established as a subsidiary to manage additional ADLS projects. In 2018, it transformed into a full service provider for ADLS with new shareholders under the name Dark Sky.
