Last night @ 01:00 UTC I went to my car and checked my TomTom GPS.
It immediately failed to acquire and I gave it a fat 15 minutes to do
so. It did display 3 of the then visible 6 GPS satellites[1] on the
"sky view" - but as "grey" (not acquired). Nonetheless it also showed 6 satellites in the channel bars, 4 of which had strong signal. But - not
in acquired "blue" state.
Time was almost correct (internal clock coasting), but location was
where I deliberately left it in the afternoon on errands (about 5 km away).
I powered it down and on again. 15 minutes later it still had not
acquired.
So, before giving up for the evening (full disclosure: SO wanted me in
to watch something on Netflix) I gave it one more power off cycle and
back on.
It then acquired about 30 seconds later. And contrary to TomTom's
bulletin, the displayed time was correct (I invoked the "sync" function
to use GPS to reset the time) and I set up a destination and the ETE and
ETA were correct. I'll see how this goes this afternoon as I have a few errands to run. Also have another legacy GPS I'll try to test if I have
the time.
(Needless to say the iPhone had no issues).
[1] the "visible" sats at the time were determined using an app called
GPS Plan which uses the latest Almanac, current location and time to
compute GPS (and GLONNAS, Galileo and QZSS (Japanese system)) satellite elevation and azimuth from the user's position. (Since Apple doesn't
have 'deeper' info from the GPS receiver available to users/apps).
Well, same TomTom seems dead now. Won't acquire. I was away for over a
week and perhaps it didn't get a chance to gracefully update from week 0
to week 1. I've attempted many restarts to no avail. I've reset to
factory. Nothing. (I'm not even sure which F/W I'm running now).
Anyway, I've disconnected it from power and will let the battery run
down and try one last time before giving up on it...
