SIRF STAR vs Other GPS chipsets
bharath_r
I have a NavSync CW19 GPS receiver which uses a Ceva chipset. I would
like to know the difference between Sirf Star family chipsets and
other chipsets available. Is a receiver which uses Sirf Star chipset
more accurate than other receivers?
Thanks

me too!
I'm trying to choose a good handheld for me and I can't decide between
the "GPSMAP 60CCSx" and the "eTrex Vista HCx" due to this 2 questions
(that www.garmin.com fails to answer):
- how does the Sirf Star III compares to the MediaTek ?
- how fast is the processor in both units?
other that that I think the Vista wins:

------------------------------
I own both receivers (60CSx and Vista HCx). They work identically,
taking into account the differing form factor and screen size, except
for the buttons.
I mounted the Vista on my motorcycle handlebars and plan to do the same
when I switch to using the 60. I'm switching because of screen size only.
When I hike, I use the Vista because of its smaller size.
The Vista has a brighter screen when the backlighting is turned on. With
the lighting off and viewed in sunlight, I can see no difference in
screen appearance. Both units are far superior to the b/w Summit I used
previously. The screen resolution and color are outstanding.
About the buttons. The 60 has more buttons and may seem easier to
operate. But once you tune into the Vista's buttons, they are no more
difficult to use. As you use your receiver, you will soon make button
selections automatically; that's why fewer buttons on the Vista isn't a
problem.
I thought that the 'rocker' (Garmin's terminology) on the Vista would
break because of comments by others that it looked like it wouldn't
stand up to abuse, but it has performed flawlessly for the 6 months that
I've owned it.
The 60 gets signal ever-so-slightly quicker than the Vista. They both
hold signal equally well in heavy cover.
I have the same map in both, and they view identically (taking into
account screen size).
I use a 1GB card in the Vista and a 2GB card in the 60 only because
that's what I had on hand. They both work the same.
Antenna and ports:
60 CSx
external antenna option
serial port
USB port
Vista HCx
no external antenna option
USB port only
You can power both units through their USB ports but the 60 can also be
powered through the serial port and there are off-the-shelf cigarette
lighter power cords that connect to the serial port for as little as $13
including shipping.
Advertised battery life:
Vista HCx - 25 hours
60 CSx - 18 hours
If I had to choose just one, I'd go with the 60 because of screen size,
notwithstanding the handy smaller size of the Vista.

If you use the Vista mounted to handle bars, I don't think breaking
the joy stick is likely. Tossing an etrex in a backpack is another
story. The 60 definitely has more rugged buttons.

There is more information in that newsgroup under the thread
"SIRFIII x series chipset type G update...". Read my posts there
along with Dan Anderson's excellent replies.

I have the 76Cx (kissing cousin to the 60). Even with the SIRF chip
set, I have encountered situations where lock was lost while driving in
narrow valleys in British Columbia. With my Garmin GA 25MCX antenna
attached I have had no loss of lock and overall better accuracy since I
get full 360 degree sky view with the antenna on the roof of the car or
in a pocket in my hat.

One advantage to the built in car nav is they use accelerometers when
the satellite signal is not sufficient.

The MTK has some issues with low speed dynamics ->
