Long Term Precision Measurements on GPS and IRIG-B Equipment

Abstract

During November 1999 the progress report of the TimWG was presented to the LHC PLC. The report contained a list of short term and medium term tests that should be completed during 2000. The PLC concluded that "The TimWG should continue its work with the objective of producing a final definition of the timing before the end of 2000". The first two items on the list were "GPS time synchronisation measurements" and "IRIG-B data transmission tests". This note contains the result of the tests that have so far been performed and they will be presented to the TimWG
