cheap GPS

Something to look forward to. :slight_smile:

Any predictions whether this will have more or fewer affects than
NIST setting daylight savings time in the wrong month a few years
ago on WWV/B?

Those wagering the GPS roller over would have fewer affects, I think
you lost. Pioneer, Japan reports they have 450 people answering phones
from customers with car GPS navigation systems which have failed. Japan's
MITA estimates 95,000 units in Japan are affected. I couldn't find anything
on the engligh-language web pages about the problem.

The US Air Force reports the satellites and control system rolled
over without incident. The US Coast Guard has received no reports
of civilian problems within the USA this evening.


It's too early to say with high confidence, but you had to stretch pretty
far away from the question you asked (will it cause time problems with
NTP, etc) to find a problem with the GPS rollover. General reports are
that it went better than expected and that few critical systems were
impacted. If you had asked whether anyone would be hit by the rollover, I
would have said of course there were going to be systems and people hit.
It may be fun to watch the PR wars that result.

BTW, I knew one person who didn't fly this weekend because of the
rollover, which seems a bit extreme to me.


Hmm, may be someone compare the predicted trioubles and the real ones -
how much predictions was not realised, how much realised in the real
troubles, and which percent of the real troubles was not predicted at all?

Good test before Y2K.
