Comparison between extension of the European EGNOS and new African ASAS network for Africa and Middle East

In this paper are introduced comparisons of the European Geostationary Navigation Overlay Service (EGNOS) and African Satellite Augmentation System (ASAS), as compatible Regional Satellite Augmentation Systems (RSAS). Both infrastructures are designed to provide service for Augmentation of the US GPS and Russian GLONASS systems over their territories only and provide improved Traffic Control and Management for all transport applications including enhanced Safety and Security. The EGNOS network is designed and built to provide RSAS service in Europe and surrounded sea areas using own infrastructures of Ground Networks and leased Space Segment. The African Satellite Augmentation System (ASAS) is projected to provide the same and compatible service over entire African Continent and Middle East including all ocean areas around the Continent using own Ground Infrastructures and lease Space Segment. Both systems can use the leased Space Segment of two Inmarsat and one Artemis spacecraft or to build own Space Segment and to improve the present transportation civilian requirements for high-operating Integrity, Continuity, Accuracy and Availability (ICAA) of the basic Global Navigation Satellite System (GNSS) signals. The both RSAS networks will allow to military GNSS-1 systems, the US GPS or Russian GLONASS, to be used as a primary means of navigation at sea, on the land (road and rail) and in the air providing data to Traffic Control Centres (TCC). The main configurations, components, characteristics and benefits of both EGNOS and ASAS networks including their comparisons especially regarding the extension of EGNOS coverage over Africa and Middle East are discussed.
