Aireon’s Space-Based ADS-B Surveillance to Cover All ASECNA FIRs


Announcement ensures 100 percent surveillance across Benin, Burkina Faso, Cameroun, Centrafrique, Comores, Congo, Côte d’ivoire, Gabon, Guinée Bissau, Guinée Equatoriale, France, Madagascar, Mali, Mauritanie, Niger, Sénégal, Tchad and Togo.

DAKAR, SENEGAL – 13 December 2019 – Following nearly two years of collaboration on terrestrial surveillance between the Agency for Aerial Navigation Safety in Africa and Madagascar (ASECNA) and Aireon, the two organizations have concluded the use of space-based ADS-B for surveillance services beginning January 1st 2020 within the six flight information regions (FIRs) of ASECNA: Antananarivo, Brazzaville, Dakar Terrestrial, Dakar Oceanic, N’djamena and Niamey.

Aireon and ASECNA’s relationship dates back to early 2014, when the two began their cooperation and studies to enhance safety and efficiency in ASECNA’s airspace. In 2018, it was announced that ASECNA planned to deploy space-based ADS-B in its terrestrial airspace.

Mohamed Moussa, Director General of ASECNA said, “Expanding ATS surveillance across key oceanic airspaces will allow us to more easily partner with regional ANSPs in these important corridors. Today’s announcement reinforces our decades-long commitment to creating a seamless African sky.”

With this surveillance expansion, ASECNA will have 100 percent real-time air traffic surveillance over the entire 16.1 million square kilometers of its controlled airspace. As of July 2019, Aireon data currently reaches ASECNA centres in two different points, Dakar and Abidjan, and is then distributed via Very-Small-Aperture Terminal (VSAT) to all the other centers.

This service expansion over water also benefits ASECNA’s operations over land. By connecting oceanic and terrestrial with the same space-based ADS-B data, the ANSP will be able to safely reduce aircraft separation minima, adding more capacity and allowing preferred routes to airlines.

“Aireon congratulates ASECNA on their leadership in deploying space-based ADS-B data in the AFI region,” said Don Thoma, CEO of Aireon. “Space-based ADS-B data will be available across all six flight information regions of ASECNA, and this partnership extends the collaboration and the benefits of safety and efficiency to ASECNA’s region.”

Founded in December 1959, this announcement coincides with ASECNA’s 60th-anniversary celebration. ASECNA is planning to celebrate their 60th anniversary by extending the scope of Aireon surveillance with this announcement to employ ATS surveillance data coverage across all six ASECNA FIRs.
