Talk:SiRFstarIII

Date of write??

Nei: Why is this at the top of the page? I haven't seen this in other articles nor seen any articles about it being a new addition to each page. I'm going to revert and ask that you explain here. No hard feelings but it doesn't look correct.Davandron | Talk 22:02, 21 November 2006 (UTC)

85.58.29.207 10:11, 13 August 2007 (UTC) I think is useful in order to see how recent the technology is. In the article it says "most recent chipset" but there is no way to see when this statement was made.

Page Rewrite

I have added some definitions , but still this page is just a copy paste from SiRF website, wich is advertising

I rewrote this page based largely on documentation from SiRF's website that is referenced in the article. --Nick 09:22, 28 June 2006 (UTC)

SiRFstar III "channels"

Regarding "20 channels", I've found a web forum post by a SiRF employee that explains in great detail how the SiRF III chip implements channels, as the tracking engine can search the contents of the signal buffer for one satelite at a time, and can do this over 20 times before the next buffer load of signal arrives. Here's the link, it's the post from Carl, dated 04/08/2005 - 21:55:11. It's a fascinating inside look at the technology, and might belong in the SiRF III article. Unfortunately, I can't find a good way of citing this as a source. Any ideas? -- Tomlouie | talk 21:37, 11 August 2006 (UTC)

"Problems with the chip"?

I don't understand the need for this section in the article. To me, a problem with a chip would be like the Pentium CPU chip math bug. All GPS chips have to content with multipath issues. I'd like to see citations that state that the SiRFstarIII has a problem with multipath anymore so that any other GPS chip. The many reviews I've read of GPS units with the SiRFstarIII all praise the chip. -- Tomlouie | talk 14:08, 21 August 2006 (UTC)

GSM and 3G

I am new to using the Wiki, and English is not my native language, so I will not edit the article, but I know as a fact, that the part about GSM and 3G is false. Some units with Sirf III may include this function, but it is not a part of the chip set.

I just read this for the first time and I agree, the chipset itself doesn't have any special cell phone capacity (although from what I understand it can be pre-loaded with data to cut down on the search window size the correllators need to run). Will edit. Davandron | Talk 15:35, 15 November 2006 (UTC)

Chipset version history; power consumption

The version history, among with key features, would be a nice thing. However SiRF website currently offers GSC3e/f only -- no leaflets describing earlier versions, of which I managed to preserve only a couple or so. Are there some backups on the 'Net? :)

For example, a certain feature now bothers me (from a completely different discussion): the power consumption.

1. GSC3e/LP eats 62 mW ("GSC3LPProductInsert.pdf") while SiRF IIe/LP (GSP2e/LP + GRF2i/LP) eats 200 mW (68 mA @ 3.0 V, "SiRFXTrac Product Insert.pdf"). A terrific improvement because of "all-in-one" approach.
2. Someone has already mentioned arrival of the /LP version which improved power consumption threefold. This is consistent with (1). Alas, I missed the first version.
3. Some time ago there were lots of desperate woes about power consumption of these new Garmins featuring SiRF III (which version?) -- some 18 hours of battery life instead of 30 with "native" chipset. Difficult to judge there because the remaining hardware of these Garmins has also improved, even if we assume that "native" chipset is similar to SiRF II in terms of economy. In general I believe that Garmin used the first version which consists of two ICs as mentioned in this article.

This page points to the wrong Falcom

This page points to the wrong Falcom for the GPS antenna. This page points to a video game maker. —Preceding unsigned comment added by 63.226.32.16 (talk) 14:30, 23 January 2008 (UTC)

Is this a Wiki Entry or Gorilla Marketing?

I found this page searching for GPS chipset information.
There does not seem to be any value to this page outside of value to SiRF.
There are unsubstantiated marketing claims that appear plucked from a press release.
There is no description of the underlying technology.
I recommend this page be removed or rewritten by a neutral party.
