Need For GNSS policy to help fast-track implementation of continent- wide satellite-based augmentation system (SBAS) for Africa

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 well-structured Global Navigation Satellite System (GNSS) policy to offer transformative potential for addressing these challenges.
