European technology that allows satellite navigation signals to safely guide aircraft down for landing in the majority of Europe’s airports will now be put to use across Africa and the Indian Ocean. ASECNA, the Agency for Air Navigation Safety in Africa and Madagascar, and ESA today signed an agreement to deploy a Satellite-based Augmentation System (SBAS) across a service region of more than 16.5 million sq. km, one and a half times the size of Europe’s coverage area.
