>From the Wikipedia article: To determine the current Gregorian date, a GPS receiver must be provided with the approximate date (to within 3,584 days) to correctly translate the GPS date signal. To address this concern the modernized GPS navigation message uses a 13-bit field that only repeats every 8,192 weeks (157 years), thus lasting until the year 2137 (157 years after GPS week zero). -- John Hasler jhas...@newsguy.com Dancing Horse Hill Elmwood, WI USA _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
