GPS Chipset Comparison - Captivate General

Can't get enough GPS threads. Well tough luck. Here is another one. But this may be more interesting. I was doing research on the different GPS chipsets that are used in mobile phones, and here is what I found.
Our Galaxy S line uses:
Broadcom BCM4751 which had built-in support for QZSS and also supports additional satellite constellations including the Satellite Based Augmentation System (SBAS), making as many as nine additional satellites available for use in navigation.
The Quasi-Zenith Satellite System (QZSS), is a proposed three-satellite regional time transfer system and enhancement for the Global Positioning System, that would be receivable within Japan. The first satellite 'Michibiki' was launched on 11 September 2010. Full operational status is expected by 2013.
On October 5th, Broadcom Corporation announced that its single-chip global positioning system (GPS) solution for mobile devices supports the new Quasi-Zenith Satellite System (QZSS) launched by Japan earlier this month. The BCM4751 solution has built-in support for QZSS and also supports additional satellite constellations including the Satellite Based Augmentation System (SBAS), making as many as nine additional satellites available for use in navigation. This built-in support will result in several GPS performance benefits, including improved urban canyon navigation in major cities such as Tokyo and availability of position fixes in more areas than competitive solutions.
Xperia X10 and Garminfone both use Qualcomm's gpsOne chipset which came out in 2007. When it first came out, the device that used that chip had horrible GPS performance. It seems that over time, improvements are made to improve the signal.
I may be wrong but in conclusion, if it's true that our GPS just started to support a new satellite and more satellites are to be launched then performance should improve over time too. Also, I really don't think the driver is fully tweaked yet.
Correct me if I'm wrong. I don't know if people have noticed GPS performance from September to October. I did lock 9 Satellites today, and I think Xperia X10's Qualcomm chip only locks 8.
Some food for though.

Now that you mention it, I did get locks on more says than in previous months. Hmm interesting... thanks for this info.

Today is the first time that I have drove home with stock standalone GPS setting with Ndrive, not google maps. Green reception all the way through. There are just 2 inaccuracies. But this is almost as good as standalone GPS units. We will see what happens. I wish Samsung will officially tell their customers what's happening.
We can say the Broadcom's ability to receive from new satellite is hard fact though.

Thanks for your research.

I thought this chip was used in other phones - did you find any others using it or was samsung the early adopter?

might be a stupid question but how do you know how many satellites you locked onto?

So then we hope it is not a hardware issue.
Although, i would think Broadcom does some decent testing, but who knows.

HTC-S730

HTC S730 ('Wings'): Has anyone spotted it already?
It's now available on Tmobiles website:
http://www.t-mobile.com/shop/phones/Detail.aspx?device=acc8102d-4506-4eaa-bc2f-9c7b8ec1b1e0
I may walk over to the local tmobile store later and see if they have one. You thinking about switching from your Vox?

Yeah, I'd like 3G (even though it drains the battery much faster).
And then supposably there is the 2nd video cam and a GPS receiver.
The cpu is apparently a Samsung running on 400MHz.
Combined with the same form factor as the S710 it sounds unbeatable to me.
Ah, that's the "Wing" in T-mobile's shop and is a different model.
The S730's nickname is "Wings"
Here's a preliminary spec:
http://handheld.softpedia.com/devices/HTC/HTC-S730--Wings-322.shtml
The release date is July '07

This S730 3G Windows Mobile Smartphone is vaporware right now
Everyone keeps saying it is coming out, but frankly, besides a photoshop'd mockup of this, there have been NO, repeat NO pictures of this in any form. No one has reported seeing one, no fuzzy pictures, etc. Until we get some information about this phone, some pictures, a release of info that is credible, I think that it's no where near release, and more like a Christmas time release at earliest. Seriously, why release the Vox, and then something that will blow it out of the water less than 6 months after the Vox release? It will cannibalize it's own market segment. I hope I am wrong, but with no pictures, or info on it, I don't see it as anything more than a future release, and nothing sooner.
Yes, it seems hard to imagine that they will release it so soon after the S710. However, there are different markets for both models. Don't forget that many users have no need for 3G, besides that the battery drains much faster. In that spec on pdadb.net it mentions only 12 hours! If that's true then many users are better off with the S710.
The Qalcomm MSM7200 chipset exists already since more than a year and does offer all those cool features. Usually mobile manufacturers need about a year to build phones around a new chipset. So from that point of view the timing could be right.
Here is more info about the chipset:

Anyhow, I would love to test a S730

D'you think the pic showing "active GPS" is for real or just a mockup?
GPS is a deal/no deal feature for me (in addition to the feeble battery... but as for the Vox there may be more powerful replacement batteries available).
Like for the Hermes there will most likely be a Wings100, Wings200... at least with different casing. Would a provider (like T-Mo Germany) be able to order units which are GPS hardware-deficient (lacking antenna, for instance)? For example, T-Mo Germany disabled (mechanically blocked!) the front videocall button of its "MDA vario II" Hermes variant.
How would one be able to tell if a specific S730 unit indeed has all necessary GPS hardware onboard?

HTC HD2

Hello guys,
Unfortunatly 80% of internet tells HTC LEO (HTC HD2) will come out with android.
And 20% of internet tells it will come out with WMobile.
Unfortunately I think Wmobile is the truth. Bcuz preorders are showing an Wmobile interface on the pictures.
My question is, can we put android 1.5 or higher on these devices?
Peace
Fortunatly, it'll be WM
Hi, I don't know where you heard that HD2 will come out with Android but from the first beginning, it has always been clear that HD2 will be running WM.
Don't wanna troll, but I would say .... FORTUNATLY !!! Just to show people what a windows mobile 6.5 device with capacitive display and snapdragon processor can do !!
Thomas
The confusion may stem from....
the fact that the Snapdragon "platform" is going to be used for many devices, there are a few nice previews of 1ghz processor equipped Android phones out there.
http://www.mobilechoiceuk.com/News/Acer+announces+first+Android+Snapdragon+phone/4133
If you ask me its all good, the more they sell, the lower the unit cost, maybe we will see cheaper WM / Android on Snapdragon in the not too distant.
Also, the 1.5Ghz Snapdragon appears to be in the pipeline too.... cant wait.
MS

I really wasn`t joking guys, maybe I get other links than you in Netherlands.
But most sites still claim its android build.
Anyways, I aint got nothing against WMobile.
I just want to know if there are already people trying to port it.
Thanks in advance.
Peace

Htc hd2 - gps
Hi,
Does anyone know what kind of GPS the HTC HD2 has (gps-enabled processor with internal antena or gps-enabled processor with a-gps support) and if it is capable of running software applications like iGo, Navigon or TomTom?
Yes, it is pretty confusing, but correct me if I'm wrong:
1. When reading specs of a cell phone and says it has/supports "A-GPS", I assume that that phone has a gps-capable processor but locking onto satellites it is being done through the Internet connection (it probably connects to a site that will tell the phone the position of the satellites) and it does not have a dedicated "com" port and "baud" rate. The navigation applications are simple and cheap (mostly based on Google maps). A good example would be the iPhone that has A-GPS only. A dedicated navigation software such as iGo or Navigon (even Tomtom) would search for a "com" port and "baud" rate so it won't work with A-GPS-enabled phones.
2. When the specs. of a phone says Internal GPS or Dedicated GPS, I assume that that phone not only has a gps-enabled processor (like above) but also has an internal antena that will help the device to lock onto satellites without Internet support (a-gps). A dedicated navigation software (iGo, Navigon, Tomtom) will work on this device because it has a "com" port and "baude" rate required for those applications to run. So, if you are in the desert, you don't have cell phone signal but enough battery, the gps will guide you out of there. Shortly put, with GPS enabled phones (not A-GPS or Q-GPS, etc) you don't rely on Internet or network signal (signal triangulation) and you can run professional navigation softwares.
So, what kind of GPS the HTC HD2 has?
I have read that this replaces the Thoth 100 but PDADB.NET still shows the THOTH coming out this quarter. Is the THOTH still alive as a separate device?
The HD2 should have a real GPS chip. as in Internal Antenna. Will take a heck of a time to lock to the satellites, tough, 10 minutes at first run. That's why A-GPS is useful (Quick GPS).
Well Said. WM forever!

Well said Thomas! Also to all others, the best thing about any windows mobile is that you can always see and check what is happening in the background or what the CAB's contents are (meaning super customisable), Android, i-phone and many others are data collecting freaks who wanna know what populations are thinking and doing. In my opinion, windows mobile Os is number 1 and always will be (check whats on ya pc.lol) second is Symbian Os! I'm sure all other mobile Os's appart from windows mobile has developed themselves using Symbian ideas!!

[SOLVED] Do both i9020 and i9023 have the NFC chip?

Hello everybody,
according to this thread and that one and to many other sources I found on the web, the differences between the two model variants i9020 and i9023 (the "original" Google Nexus S), only concern non-NFC-related things.
However, today I read several times (most popular source: Wikipedia article about Nexus S) that only the (more than twice as expensive) i9020 has a NFC chip onboard. I am pretty scared, cause I just ordered the i9023 yesterday and was happy about that good price (280euros) ... the i9020 on the other hands costs around 700euro here in Germany.
Maybe some of you (already owning a i9023) can shed some light into this. Thanks in advance!!
pbyte
I have nfc on my i9023. ;-)
These typos was sent from my Nexus S [I9023]
I have NFC-chip in mine too.
Too bad I can't use it for anything.
Good news! I hope that Samsung didn't change something in models that were manufactured very recently.
@mrhaxx1 Why not? As far as I know at least Read-mode is enabled by default, whereas Write-mode, P2P and Card Emulation modes are supported by the NFC chip, but disabled in Google's (custom build) pre-installed Android version. Is it possible to re-install another Android build in order to enable the whole stack?
Yeah my i9023 does. Even in oz, although I haven't been able to use it yet.
Sent from my Nexus S using Tapatalk
Think both have NFC. The only difference would be the display, 9020 has the SAMOLED screen and the 9023 has the SLCD screen ,hence 9023 is cheaper.
I'll leave this here http://forum.xda-developers.com/showthread.php?t=980741
It's given NFC a very good use for myself as well as quite a few others so far - worth a look if you want to try to use NFC (with a minimal initial investment to get some blank tags).
@krohnjw Ah, I already stumbled upon your NFC apps in the Android app store. Can't wait to receive my i9023 and check out your apps.
I actually ordered the i9023 in order to get down on NFC development with Android. What are your experiences with that device so far? Could you make it work to enable the whole NFC protocol/mode stack? I'd be glad if we could share some experiences ...

From the Development side there's a fair bit of functionality already within the API itself. As far as accessing card emulation and the SE, that code is present, but not public. Access to the SE is likely to be tightly controlled. We'll see what road card emulation goes down ultimately. Given Google's last talk regarding NFC and card emulation it seemed that for the userspace apps they were pushing Ndef Push in place of card emulation. The emulation code is present in the source though (just not public or part of the API).

I've read that too. Did you make a custom build from the sources in order to make use of all NFC-functionality that is implemented + available (or is such a build publicly available)?

Yeah ... from what I've read so far the concept of a SE makes perfect sense for applications that require ultimate security or are built upon existing Smartcard infrastructures, but given that space is very limited and it is still not clear (at least here in Europe/Germany) which authority will be responsible for assigning/issueing those (MNOs or 3rd parties), I think that I'll rather focus on more lightweight workarounds were possible.
The Google talk you've mentioned ... I guess you mean the ones from I/O 11? (Haven't watched them yet)
Today my i9023 arrived ... what shall I say ... a great device. NFC onboard. Display colors/contrast are superb. Now let's rock!

HTC or Samsung with Assisted GPS (A-GPS) will meet your requirements. A-GPS allows you to get a "fix" when you are indoor and connected to the Internet, or while performing a synchronisation with a computer connected to the Internet.
There is nothing much we can do about the GPS receiver (radio) because it is part of the phone's main board. The user's preference and settings is pretty much limited to the GPS software and maps.
For me, I am still using my 2009 HTC Touch HD on Windows Mobile 6.5, using Garmin XT software. In my location, there is a forum that has free open-source map resources.
Hope this helps

Thanks. However I want to use the GPS without internet so without A-GPS. Even if the radio is integrated in the main board there can be some differences between the brands. What I would like to know is from that univers, which are the best smartphones with best GPS performance without A-GPS.

I already read a lot of reviews. About GPS performance almost nothing is written. The site where I found more detail it's gsmarena.com.
Neverthless when it's said that the performance of Galaxy S is the same of Galaxy S3 ou S4 or other brands I cannot take my conclusions. The only comparison that I made it was with an iphone 4S and during the test my galaxy lost some times the signal and iphone no. Always connected! But I prefer Android so I will stay with Android.
If you know other internet sites where I can see more details please advise me.
Thanks.

GLONASS support and how to use it?

I was reading about a brand new Asus zenfone4 and I read that zenfone4 is supporting GLONASS then I was curious is our nexus 5 is also supporting it then I do some research, I found out that nexus 5 is also supporting it
My question is, is GLONASS more accurate than ordinary GPS? And how to use it? Thank you

It will just use it if available. GLONASS is a Russian equivelant to GPS, which is American. It depends where you are in the world and I don't think there is anything to suggest either being more accurate. They're just 2 different systems ofering identical functionality
