1999 GPS Time Transfer Performance

Abstract

In the 1990s, the number of military and civilian government agencies who have become dependent on GPS for accurate timing and navigation has consistently increased. The GPS Operational Control Segment (OCS), using information provided by the United States Naval Observatory (USNO), maintains the GPS timing signal well within specifications. This paper summarizes the 1999 performance of One-Way (Direct-Access) GPS time transfer for authorized users. Data from previous years will also be presented as a means of comparison. Additionally, the paper briefly covers some recent GPS Master Control Station (MCS) activities affecting the GPS signal.
