The Nigerian Airspace Management Agency (NAMA), has completed the test run of the Satellite Based Augmentation System (SBAS).
The NAMA had successfully carried out the demonstration flight to improve the accuracy, integrity, and availability of the signal through augmentation of the satellite systems with its $8.5 million Beechcraft King Air 350i aircraft.
The SBAS are used to enhance the accuracy and precision of an existing GPS system.
The GPS by itself isn’t sufficiently accurate to do things like help land airplanes or other applications where there is a need for high accuracy combined with high consequences for failure. Simply put, it means using satellite systems for air navigation.
