The last rollover was on August 21, 1999. There is a non-zero chance that the date reported by some GPS receivers will start reporting a date in 1999 when this occurs. Most modern GPS receivers handle this reasonably well by assuming that the date reported by GPS is after the build date for the GPS firmware, which means they will report the correct date for 20 years after the firmware build date. I am only mentioning this here because I know that many of us rely on GPS for various date/time functions. Note that this should not affect in any way the 1PPS signal used for timing for cambium and other radios since that will be the same alignment regardless of what year the GPS thinks it is. -- - Forrest -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
