The Agency for the Safety of
Air Navigation in Africa and Madagascar (ASECNA) signed a contract with Thales
Alenia Space, the joint company between Thales (67%) and Leonardo (33%), on
February 8 in Dakar to conduct a preliminary design study (phase B) for its
program to develop a Satellite-Based Augmentation System (SBAS). ASECNA’s SBAS
is based on EGNOS (European Geostationary Navigation Overlay Service). In line
with the agency’s strategic plan, it aims to enhance navigation and
surveillance operations during all flight phases, as well as significantly and
sustainably improve flight safety and efficiency in the areas under its
responsibility.
Starting in 2021-22, these services will improve the positioning performance of
existing satellite navigation systems, such as GPS or Galileo. The new system
will improve precision, down to within a meter, integrity, availability and
continuity, guaranteed for safety-related applications. Other business sectors,
including maritime, rail and road transport, as well as agriculture, could
benefit from these services, which will help drive economic and social
development.
The phase B study should enable countries belonging to ASECNA to define the
best system architecture to support the delivery of SBAS services, and to
ensure transparency during the following development, deployment and
operational phases. The study is being financed by a grant from the EU-Africa
Infrastructure Trust Fund (EU-AITF), through a financing agreement with the
French Development Agency (AFD). The European Commission and GSA (European GNSS
Agency) will provide technical assistance as part of an international agreement
between ASECNA and the European Union, also including the French space agency
CNES (Centre National des Etudes Spatiales).
The design study to be carried out by Thales Alenia Space will last for 18
months. During this period, the airlines associated with this program will be
able to test a pre-operational service. “Today’s contract signature marks the
culmination of ASECNA and Thales Alenia Space’s work on SBAS over the last few
years, and we are very pleased” said Jean Loïc Galle, President and CEO of
Thales Alenia Space. “Following the KASS project in South Korea, this latest
export success for a complex and powerful satellite navigation system is the
result of our involvement in satnav programs in Europe right from the outset,
in 1996. ASECNA will be able to draw on our 20 plus years of experience to
ensure passenger safety, clearly reflecting our watchword, ‘Space for Life’.”
Mohamed Moussa, Director General of ASECNA, said: “This contract marks a
milestone in ASECNA’s SBAS program, a key catalyzer for Africa’s ‘Single Sky’,
which should eventually enable us to improve landing safety and routing
flexibility and efficiency, while making isolated regions more accessible
without requiring any additional technical and human resources at airports. It
also illustrates our progress and shows ASECNA’s ability to embrace and apply
the latest innovative technologies, for the greater benefit of inclusive
economic and social development in Africa.”
