Abstract
Satellite-Based Augmentation System (SBAS) deployment on a continental level
would allow for CAT-I approaches on all runway ends, greatly enhancing the safety and
operational efficiency in the approach phase. The aerospace sector is a critical component
of Africa’s economy, connecting people, goods, and services across the nations, regionally
and globally. However, the current navigation infrastructure particularly category 3 level of
Instrument Landing Systems (ILS) faces challenges in meeting the increasing navigation
demands beyond the major cities in Africa for safety, efficiency, and precision in aviation
operations.
The article provides SBAS service demonstrations in some African countries including
Nigeria, benefits of Satellite-Based Augmentation Systems (SBAS), coupled with a wellstructured Global Navigation Satellite System (GNSS) policy to offer transformative
potential for addressing these challenges.
