Development of New GPS Performance Standards

John Anton, Robert Hessin, Joseph Sapp and Rob Conley

Abstract:	The removal of Selective Availability (SA) is history now, but we are still dealing with the implications of this decision on the management of GPS. The U.S. Government has been working since May 2000 to develop new performance standards in the absence of SA. The challenges encountered in the process have occurred on many levels: technical, operational and institutional. The process has been complicated by the U.S. Government’s commitment to provide the best possible product to the user community. The purpose of this paper is to provide a status of the performance standard development project, in the context of the complexities involved in development and implementation. The paper deals with the specific considerations involved in defining sustainable performance standards, and how those considerations have shaped the U.S. Government’s perspective on providing an international utility. The paper ends with a definition of the standards recommended for adoption by the U.S. government, and some observations concerning their implementation.
