Africa and Madagascar (ASECNA) announced today their continued commitment to the Single African Sky initiative by installing a third Aireon Service Delivery Point (SDP) Dakar, Senegal, operations centre. This tertiary SDP installation allows ASECNA to receive triple-redundant data to all six ASECNA controlled Flight Information Regions (FIRs)- Antananarivo, Brazzaville Dakar Oceanic, Dakar Terrestrial, Niamey and N’Djamena – over three independent telecommunications lines. Each line is also feeding data into the ASECNA AFISNET Very-Small-Aperture Terminal (VSAT) network, making space-based ADS-B highly available in the region.
