SPOT II GPS Chip?
Pegleg
Spot IIs? I know they have all been recalled due
to performance problems but don't know if it was
due to general unit performance or gps chip
sensitivity. Supposedly the II was using a newer
chip.

a more sensitive version.
I 'believe' the problem is the battery indicator saying the batteries
are flat when they are fine. Power cycling gets rid of the low battery
indication.
No problems at all with SPOT 2 in the field but you cannot register
new ones at the moment.

defunct and I cannot find anything about them that is less than a year
old.

They did! Maybe sombody bought whatever assets
they had. Spot won't reveal who makes the chip
they use which is rather disconcerting.

now. SiRF or u-blox seem pretty stable suppliers and if Spot have
chosen another supplier that goes out of business then that will not
stop the chipset in a delivered unit from working. The operating mode
for their equipment depends on a good sky view to allow the messages
to be sent up to their service provider's satellites which makes the
GPS reception the least of their problems.
Equipment suppliers are often somewhat coy about providing detailed
parts lists for heir products ;-)

chipset on the GPSmap 60Cx/60CSx/76Cx/76CSx
Not a big deal

Well that kind of bugs me since I just suggested someone get a GPS60
unit based on the experience I have with my own.
I recently visited a location of an airplane crash site that years ago
I couldn't mark due to my old emap not being able to lock under dense
canopy. The Sirf III in the GPS60 had no issues at all.

The GPS 60 (and GPSmap 60) do not use SiRF or MTK
Different receiver in the GPSmap 60Cx/60CSx

Sorry, no info on the chipset inside the SPOT v2. SPOT v1 was the
rather insensitive NemerixV1, but it was very low power. Nx3 was based
on the GloNav chipset and didn"t bring much to the plate. SiRFstarIV
would seem ideal for the SPOT with it's SiRFAware mode, it's not out
yet though.

New chipset is UBLOX. Info from this site

Good catch, although the fact they write Nemerix : Numerex is not very
encouraging !
uBlox is not excatly known for its low power use, wonder what's that
going to do to the battery life of the Spot v2.

Maybe it's me, but going to AAA batteries sucks. I suppose it's OK for
messaging, but I would hate to use it for tracking and have to keep
replacing AAA cells.
I don't see much in the way of improvement. I keep mine in a small
peltor transit case, so the covered buttons are not an assume. I
figured from day one if this units can alert S&R, I damn well don't
want to create a false alarm. I think it's a Peltor. I can't make out
the marking on the case, but it fits like a glove.

purpose.
The spot devices are used to send emergency alerts up to orbiting
satellites. This implies that there is a clear view of the sky to
allow the spot to send its report. Transmitting to a satellite with
the sort of omni antenna built in to the spot means that there must
not be any obstructions between the unit and the satellite. Working
under tree cover is probably beyond its capability. If the device
cannot transmit a position report then whether or not it has a GPS fix
is slightly irrelevant.
A navigation device, on the other hand, should work wherever there is
a signal. Sensitivity is far more important in this case.

Where did you get the information that Nx3 was based on Glonav
chipset?
Keith
Actually let me rephrase, Nx3 used the Ceva IP and Ceva became Glonav.

Ok! :)
