Darius, there are many reasons, most which are of no benefit talking publicly, but for example to quote publicly available material:

http://focus.ti.com/general/docs/wtb...=Other+OT+agps

There are clear benefits to having a solution that is integrated to the OMAP2420 chipset that the N810 is using, i.e. using the TI GPS solutions with the TI chipset that the device is using. Issues like price, power management, integration of feature, benefits in overall SW architecture etc.

If - and clearly since - you are interested in speculation, you can also read things like this:

http://wirelessanalyst.blogspot.com/...-acquired.html

It also talks about the importance of integrated solutions.

Never heard of A1, A2 or A3GPS. And I can't find any info about it, could you give a link or something? I'm interested.

Once the signal is acquired, what's wrong with the TI chip that would be better with the SirfIII chip?

Here's the thing Darius Jack, Nokia chose Ti, Apple chose Broadcom, and Motorola, RIM, and I think Google chose SiRF. It's all about partnership and maybe how mature the GPS chipsets are plus support, connectivity, and openness for standard features such as aGPS (or InstantFix for SiRF). There can be a lot more other reasons but for the meantime, the GPS on both devices does their job.

You have been quite a character over at the maemo.org mailing list. You have been called a lot of different names there as you have been spamming the list with your unhelpful, stubborn, and egotistic remarks. I've also seen articles and articles about your reputation from different forums and blogs.

If you are here to just attack members and disrupt the community, please find a different forum or site with folks that are willing to compete and spar with you.

That has absolutely no bearing on your request for strategic business intel. And no one's rights are being hurt.

no more poetry.
asking questions is nothing about egoism.

Your are totally wrong.
I use one name.

How a community can be disrupted with asking clear questions
about a market product ?
It makes no sense.

As I remember I have asked you one question 2 years ago about
geocoding and got no reply.

Exactly.
Egoistic remarks are made by oponents of Sirf III quality in N810
(just read about 100 responses thread about netter gps in N810).

Shame on you Reggie.
Why are you against better gps in N810.

Why clear question like
why not Sirf III gps quality navigation in N810, iPhone
can hurt you ?

It makes really no sense.
If you know answer, just give answer + references.
That's all.

Sirf III is a standard in gps navigation,
and if a world-wide standard, why not in iPhone, N810 ?

Very clear and basic question and it hurts nobody.
Know answer give answer.

And stop your poetry.
In the interest of Nokia is to make better products, offer better quality
and hot gizmo products.

Today iPhone is hot gizmo, so let maemo to be next turn hot market gizmo.
Not interested ?
Shame on you.

And don't be childlish saying

"
There can be a lot more other reasons but for the meantime, the GPS on both devices does their job.
"
What job ?
Better job does Sirf III gps.

And don't take it personally.
Asking basic questions can not hurt anyone.
If you find asking basic questions on your forum as an attack on you
and your friends
just ask users not to ask questions.

But I really don't what what's your problem.
Just do your best to build better maemo, better release of N810 to be full market success.
If you are against market success of maemo .... by Nokia ...
I have nothing more to say and add.

Darius

OK, so here's what we've got so far:

1 - Darius doesn't understand aGPS, despite it being explained many times.
2 - Darius thinks that we know why Nokia chose to use the TI chipset instead of the Sirf
3 - Darius thinks the Sirf chipset is superior. He is probably actually right here.
4 - Darius thinks that shouting will get Nokia to stop using the TI chip and succumb to his will and replace the TI chip in his N810 with a Sirf chip
5 - Darius thinks that Nokia used the TI chip just to annoy HIM, as part of a personal vendetta against him

Have I missed anything?

Never heard of A1, A2 or A3GPS. And I can't find any info about it, could you give a link or something? I'm interested.

I've never heard them called that, but there are lots of competing (read from different providers) ways to do "AGPS". Off the top of my head:

LTO (long time orbit or somesuch) which provides very accurate ephemerides (i.e. more accurate than the ones you'd download from the sats) so that you can then go without updates for something like 6 weeks with reasonable accuracy. This is called lots of things and is offered by a number of providers.

There's our basic AGPS (i.e. in the N810) which is probably just the delivery of almanac + standard ephermerides.

There's also services which will take partial signals from the chipset and then brute-force them to work out where the chipset had to be to receive such a signal (i.e. offloading the processing for poor signals).

Probably more than that too!

Sirf III is a standard in gps navigation,
and if a world-wide standard, why not in iPhone, N810 ?

And the answer is we don't know. Ask Nokia. And say please, as I'd quite like a Sirf Star III chipset in the next device

Please also post some links to your comparison research on the chipset powers and costs.

6 - Darius thinks Sirf star III is a world-wide standard. I wonder if that's according to ISO or SI or what..
7 - Good arguments are to be dismissed as "poetry"
8 - When quoting a message, one should always quote it all and not bother trying to reply to specific issues, thus making sure the big mess continues.

As to gps chipsets, there's no Sirf star III in my Holux GPS receiver, and, amazingly enough, it works equally well, or even better than the world standard chipset.

9. Darius suspects that we and/or Nokia as a company want the N810 and similar products to fail
10. Darius thinks that this is the place to challenge and change Nokia policy
11. Darius thinks I'm one hell of a poet

Hey, 1 out of 11 ain't bad!

Well, remebering the Office Open XML certifcation i wouldn't be surprised about it being ISO standard, but i guess SiRF Technology had more important things to do
