Here is an excerpt from the Binomial Disaster Recovery Newsletter of
6 Aug 98. One of their readers wrote in about... "...an incident that occurred in the spring of 97
when one of the Air Force's GPS satellites malfunctioned and broadcast
the wrong time signal for a brief period which had an unexpected effect
on various cellular and PCS carriers across the country.
In chasing down what had happened, I had occasion to speak to an official at
DoD's National Communications System. DoD was, of course, aware of the problem with the satellite but
they had no idea that the telecomm industry made such extensive use of the
GPS system. There were procedures in place for the AF to notify fliers and
seamen of problems or planned outages but nothing in place to alert the
telecomm industry or the public at large. They are doing better now and
they have been very forthcoming with information, available to the public,
with regard to the EOW Rollover and Y2K problems which face the GPS user
community in August and December..." specializes in Business/Disaster Recovery
