Completely wrong.
AGPS by Motorola A1000 was introduced exactly for the reason
gps chip was not Sirf III.
What you call instant lock/fix is another type of A2GPS
and I say nothing against Sirf III GPS + network fix assistance.

But the implemented is old (non- Sirf III GPS chip) + network fix assistance.
Exactly the old solution. A1GPS.


It's not even a crutch. The way the GPS system works there is _no way_ to get instant lock (particularly from cold start) without using assisted GPS. It's _always_ useful to have AGPS, or any system that does the same (=>pre-loading data that one would otherwise have to wait for).

Who said otherwise.
A2GPS is ok.
A1GPS is not a good solution (for definitions see above).

> $10 is in this context an enormous amount of money.

Mayby yes mayby not.
I got $100 car navigation devicer as touch screen + maps + routing + Sirf III chip included.

So I don't see extra $20 for full GPS in N810, iPhone makes any difference for a knowing buyer.

Device producers are always trying to shave off a cent here, a cent there, if they can, because it all adds up to the bottom line. In any case, nobody in this thread will know the authoritative answer to the choices, there's just a good guess that the cost, plus the power (battery) requirements are both lower for the TI chipset. But we're not Nokia.
"
ok, ok, ok
for the same reason I decided not to buy any model of iPhone without full Sirf III gps navigation.

"
It's probably not much use to keep replying though.. so I won't bother after this one.

I have offered gps solutions for iPhone/Apple (Skyhook)
better, faster, more efficient algorithms for AGPS .

size is not an issue - what is a size of aGPS chip in N810, iPhone ?
have you done size comparison ?

price is not an issue - Sirf III chip $10 a piece (wholesale price much lower)

<snip>

battery life is not an issue - you can still offer 2 models , one with full GPS and one aGPSed.

Think twice.
aGPS was offered for non-gps enabled iPhone by Skyhook
as add-on, not mainstream gps solution.
The idea was great and it worked as it worked.

Today Apple released gps enabled iPhone and still not full GPS (Sirf III).

None of the above listed issues by you is valid.

To me aGPS is still 3-wheel + 1 leg solution for car industry.

Are you speaking for Nokia this time ?


If any Nokia employee emails you proprietary info I will personally see to it they don't get the opportunity again.

I can assure you I don't have any problem

___
A-GPS is a way, using network capabilities of your phone (or wifi) to have a clue of where you are, and then give this info to a GPS chip to get the fix quicker.
___

There are at least 3 AGPS solutions.
One in no-gps iPhone (Skyhook) - network database based pseudo GPS

Second is A2GPS for devices with slow processor, slow gps chip

and Third is A3GPS for Sirf III like gps chip based devices.

______
As both in N810 and new 3G iPhone we discuss A2GPS

_________
Both N810 and iPhone have a GPS chip, and they both could give you your position without A-GPS. A-GPS only comes there as a support.
___
exactly
support to non-Sirf III gps chip like quality


The N810 has a Texas Instrument chip, which is not so good to get its first fix but is good for other things(battery life, keeping the fix,...). To make the first fix quicker, Nokia introduced, as software, A-GPS. It improved the TTFF for most of us. Same goes for the iPhone.
___
Exactly.
A2GPS solution.

So what about A3GPS ?
keep network assistance alive and offer Sirf III gps chip alike quality ?

I expect, lately announced release of new iPhone is exactly
A3GPS solution (network assistance + Sirf III like navigation quality).

I still remember poor gps quality in Motorola A1000, called aGPS (developed 5-6 years ago)
_____________

Now, as your question is: why didn't they put the best GPS chip (aka SirfIII) in the N810 and iPhone?
___
Not best.
Sirf III gps quality is market standard nowadays.
__

it's like asking "why didn't they put a Ferrari engine in my VolksWagen?"
__
Nope.


And asking, us or Nokia about that is as pointless as asking VolksWagen. They made the choice they thought was the best.
