Selective Availability (SA), a mechanism adopted by the Department of Defense to control the achievable navigation accuracy by nonmilitary GPS receivers, is discussed, along with the May 2000 decision to discontinue this intentional degradation of GPS signals available to the public. Aviation and maritime GPS applications, among others, will benefit from the discontinuance of SA. This chapter examines mechanisms to implement SA and reviews SA models described in the literature.
