Abstract:	Proper GPS positioning, navigation and time transfer capabilities are essential to many industries in terms of economic benefits and public safety. With the new millennium nearly upon us, the urgency to confirm proper operation of various GPS receivers during all Year 2000 (Y2K) epochs is increasing. This urgency is the motivation behind a series of tests designed to identify if GPS receiver is Y2K compliant. Several critical epochs apply to GPS including; (i) GPS Week Roll Over 1024 (WRO1024) in August, 1999, (ii) century roll over from 1999 to 2000 (Y2K), (iii) leap year day of February 29, 2000 (Y2KLY), (iv) year roll over from 2000 to 2001 (new millennium) and, (v) various end-of-record (EOR) dates. A test plan designed for evaluating a receiver’s use of almanac and ephemeris data before, during and after all of the critical dates described above using a GPS signal simulator is presented. Finally, a procedure for assessing receiver compliance in various domains is included.
