Civil Aviation's Need Beyond GPS-Based Systems

Robert P. Crow

Abstract:	Global civil aviation is rapidly moving toward utilization of GPS and it’s substantial navigation advantages. Much development is also in progress toward using GPS for global ATC surveillance, collision warning/avoidance and precise landing guidance. However, although these GPS-based systems offer major advantages over existing systems, there are critical shortcomings involving integrity, availability and security which cannot be practically solved with GPS or GNSS-based type systems. Recognition of this fact is necessary now so that planuing of evolutionary changes can be made toward a system meeting all the requirements. It is believed that such a system called the Integrated Global Surveillance and Navigation System (IGSANS) will meet the requirements. It is a combined ground/satellite based system which would provide substantial cost savings in both the airborne and ground/satellite facilities. IGSANS will be briefly described in subsequent sections.
