Motivation: Important satellite missions, amongst which are USA, Chandra, and CGRO, have had problems with the absolute times assigned to events. See the anecdotes at the end of the page. The 10 uS timing precision required for the GLAST LAT is _essential_for good pulsar science. In addition to extensive testing of the different links in the timing chain, we have proposed an end-to-end test which will be the main focus of this page.
Minutes of telecon 11 October 2006: It is looking like we will go to Arizona the week of November 6th, to shake down and install the system. The NASA project office has approved our test. Spectrum has GPS cables and will get the right kind of connector for us. The muon telescope will sit right next to and slightly below the LAT. Thetest could be during the 2nd week of December.

Presentation made in SVAC IA meeting, 16 June 2006 by Smith. It builds on an IA presentation by Anders Borgland on 26 May. The thread continued with presentations by both Anders and Warren Focke on 30 June ; and Warren again on 14 July. You can find all these at the IA meetings page, http://www-glast.slac.stanford.edu/IntegrationTest/SVAC/Instrument_Analysis/Meetings/agenda.html
