Modernization of the Global Positioning System

Kanwaljit Sandhoo, David Turner and Michael Shaw

Abstract:	More than two decades have now passed since the construction of the GPS operational control segment (OCS), including the Master Control Station (MCS) at Schreiver AFB, Colorado and worldwide monitoring stations, and launch of the first GPS satellites. During that time, several generations of satellites have been designed, built, and launched, and operations are routinely supported by the OCS. Today, Global Positioning System (GPS) is entering into the new millennium with a far-reaching program to modernize the system on the ground and in space. This paper describes the goals, requirements, design objectives, and plans for implementing a $1 billion- plus modernization program in the coming decade.
