GPS Chipset - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

I read somewhere that the Galaxy Note is equipped with the SirfStar4 chipset...
Can anyone confirm that? And if possible with a link to the documentation?
Thanks

Galaxy Note uses Broadcom BCM47511 as GPS chipset
Hello betoNL,
According to a Broadcom press release, the Samsung Galaxy Note uses their BCM47511 chipset, for GPS (American) but also GLONASS (Russian) Global Navigation Satellite System(s) (a.k.a. GNSS, the generic term for GPS-like systems). This chipset, which is a direct pin-to-pin replacement for the earlier BCM4751 chipset, adds support for the Russian GLONASS system, so that either or both GPS & GLONASS can be used according to best available signal strengths. Thus speeding acquisition and improving (slightly) accuracy.
I notice that Broadcom have now starting selling their next-generation GNSS chipset, BCM4752, which adds the Japanese specific Quasi-Zenith Satellite System (a.k.a. QZSS, a regional solution using quasi-geo-synchronous satelites that oscilate North-South between Japan and central Australia), along with GPS & GLONASS. This chipset also advertises that it uses unspecified Satellite-Based Augmentation Systems (a.k.a. SBAS, like maritime Differential-GPS but via satelite) - presumably at least WAAS (North American continent) and EGNOS (Europe) would be support, but no mention of implementation details: e.g. is host system software required?
Broadcom suggest that smartphones using this new chipset should start being released in Q4 2012, meaning right now (2 weeks left before Christmas), but I cannot find any examples of that yet. When that happens, the new smartphone concerned would be (due to absence of Sirf Star III/4) the first to have GPS-style location using correction information (A-GPS only pre-loads the basic satelite almanac via Internet, rather than waiting for it to dribble down from the GPS satelites themselves, thus saving time for the first-fix).
This new BCM4752 chipset also advertises reduced power - compared to BCM4751/BCM47511. As well as the possibility of using external sensors (accelerometre, gyro) and other information such triangulated Wifi and/or Bluetooth signals - specifically to improve indoor operations.
Getting back to your specific suggestion that a Sirf Star 4 might be involved: I have not been able to identify any smartphone using this chipset, nor the Sirf Star III which is what is was actually looking for when I came across you still-unanswered post. Apparently some purpose built GPS tablets, running Android but without any telephone capability, do use the Sirf Star III (at least) which already gets correction information via SBAS. But Broadcom & Qualcomm seems to share the smartphone market (Android and iPhone).
Best regards,

Hello Neil,
Thank you very much for your excellent, very informative and complete post.
As you noticed (or not ), I posted my question around one year ago, when I was thinking about buying the GNote and I did buy it!
The gps performance on the GNote is indeed excellent, on all my onboard/offline gps car navigation software.
In the meantime I already moved on to the GNote2, which also got Glonass support and probably got the same gps chipset as his predecessor and a even better gps performance ( locks to satellites a little faster, even indoors , without the need of agps support, of course)
If it's correct, that the GNote2 got the same chip or similar(upgraded) , allow me to quote your excellent post, on the GNote2 forum also.
Best regards and thanks again,
Beto
Edit: If I remember it correctly, there were some very old HTC phone models equipped with a sirfstar chipset, but it seems so long ago...

Can anyone confirm if the note will switch automatically between gps and glonass. Mine always says location set by gps.

Well, I own a note 2 now and Just like the note 1, once I am outdoors, and I open for instance gps status app , I can see sometimes device is viewing 22 or 23 (or maybe more) satellites, much more than any other device I owned before, so I can only conclude that the phone is combining both systems:
GLONASS is a radio-based satellite navigation system, the Russian equivalent to the U.S.’s GPS. GLONASS was initiated during Soviet Union times but had then fallen into disrepair, it has since then been upgraded in various stages and can now begin to rival GPS — GLONASS is actually more accurate than GPS in northern latitudes because of the positioning of its satellites.
The biggest benefits, however, come when you combine both systems together, GLONASS and GPS; this allows a device to get more accurate positioning and/or faster fix, particularly in deep urban environments. This is because you suddenly have access to the US GPS 31 satellites and the Russian GLONASS 24 satellites for a total of 55 active satellites.
Below is a test that was ran showing the improvement in accuracy by using both systems together:

And even if it's not combining both systems, that's not really relevant, cause performance over here, is outstanding, anyways (fix speed and accuracy)....

Galaxy note series has one of the best gps chipset available and it is way ahead of its time. No other phone has such a powerful gps.

Perhaps some of the devices do, but not the GT-N7000. I have that model, and when I capture nmea data I see some proprietary messages unique to the Broadcom GPS chips.

Thanks man, but first post is more than 1 year old and it was detailed answered 6 posts above...

I think one key difference between the Broadcom chipsets that isn't mentioned here are the number of tracking channels and corresponding maximum satellites tracked.
The BCM4751, 2076, 4761 only have 12 tracking channels with an equivalent maximum satellites tracked. This is fine for GPS only devices, but quite limited for multi-constellation chipsets.
The BCM47511 up's the tracking channels to 18 with an equivalent max tracked.
The BCM4752 is listed as >100 channels, with a maximum tracked of >35.
Not sure if any devices use the BCM4752. Couldn't find any information from searches.

Galaxy S2 uses SiRFstarIV.

Unfortunately it is Qualcomm which is not the most relible at the moment.
But, it is true, it is one of the best implimentations of BT v2 at the moment. The big problem is, not every device that quotes v2 is any form of a full version, just as versions of WiFi vN is not fully compatible as it has not been fully agreed on within the international market!
Not all BT audio devices that quote v2 are fully compatible and the worst at the moment seems to be early versions of Parrot equipment. It is one of those aspects that people have to experiment with and not initially blame the 'Kaiser' for without testing.
Class 1
Is there any way to convert to Bluetooth class 1 / increase the range / strength / amount of information being sent from the tilt?

I think that should say 'revert' and no, it is hardware specific.
BT power output is set by standard international agreement and changing data package would only compound the incompatibility with other devices.
BTW, why would you expect and earlier version to give you increased performance??

Qualcomm MSM7200A & MSM7600 Differences?

I guess the MSM7600 is CDMA whilst the MSM7200 is GSM?
EDIT:
MSM7200 is GSM only
MSM7600 is GSM/CDMA dualmode, which would explain why the Sprint Rhodium FCC listing says it's got GSM disabled...

I really fancy a TP2 and I may be reading this completely wrongly, but . . .
my Touch Diamond has a MSM7201A processor which is newer than the processor in the TP2 and is 65nm technology, whereas the MSM7200A is 90nm
Have HTC done some form of tweaking to give better performance from the TP2 because if not it doesn't sound like a considerable upgrade on what I have now

MSM7201A is not newer than MSM7200A. They are the same generation processor. non-A is 90nm, A is 65nm. 0 is original chip, 1 is with patent workaround. 0 outperforms 1, patent workaround introduced some performance issues.
Laymans term, 7200A is 65nm and faster than 7201A.
TP2 = much faster than TP (probably mostly related to tweaks we had in our custom ROMs anyways, and faster flash and ram chips).
Why do I need to keep telling people this....

This is a typo, should be WM 6.x refresh, i.e. 6.5, which has been said to be released on actual phones in September for ages now.
By patent workarounds, may I hopefully assume it's concerning the hardware video acceleration part? If so, may I also hopefully assume the TP2 has some built in use of that part of the chipset??? Please.... My old HD is getting wore out and I need an excuse to upgrade
Thanks Chainfire... many respects...

The patent issue AFAIK only has to do with some 3G stuff (I don't know how this relates to the performance issues of the 1 variant, though, I know there is something with that). Still TP2 does have HW 3D video - but so do the Diamond, TP, HD, and Diam2. The TP2 (and TD2) is noticably faster than the HD, though.

Actually, it would have been better if you could put some references about your comments. Especially this one: "Laymans term, 7200A is 65nm and faster than 7201A."
It seems you're right about patent issue (though it is hard to find anything about that), I found this site: http://www.scribd.com/doc/2140146/tag1202114pagenews1tQualcomm-Launches-UMTS-Chipsetsd578, which says:
" In December 2007, US federal judge issued an injunction against Qualcomm for infringement of three Broadcom patents and ordered it to stop selling 3G wideband code division multiple access (WCDMA) cellular chips that breach Broadcom patents. The company has launched the mobile station modem (MSM) 6271, MSM6281, MSM7201 and MSM7201A chipsets in the US. According to the company, the new chipsets are pin- and software-compatible with the existing product versions for easy transition. "
So if the site i'm referecing is reliable, then you're right about this.
But where did you get the info about the 65nm? Could you give us some references? The only site I found (where the size is mentioned) is this: http://pdadb.net/index.php?m=cpu&id=a7200a&c=qualcomm_msm7200a and it says it is 90nm.
What's more interesting that on this site: http://www.qctconnect.com/products/msm_7201.html#Technical Features It says: "Qcamcorder™: Record up to 24 fps QVGA"
Meanwile here: http://pdfserv.datasheetpro.net/QUALCOMM/msm7200a_chipset.pdf
"Qcamcorder™ Encoder
• A real-time wireless video recording solution that captures movies at 30 fps WVGA"
(this datasheet - by the way - mentions lots of interesting infos)

Perhaps if you asked nicely. And even then I'm inclined to tell you to UTFS (it's not like this is "new" information)
EDIT: BTW, seems I didn't mention it in this thread - I did in another - it does indeed seem that the US TP2 (non-Sprint, which will use MSM7600 series) is MSM7201A, while the EU (and possibly Asia) versions use MSM7200A.
Did you guys forget Xperia X1? It also uses the same processor like the Touch Pro2.
A thread like this has been discussed in X1 forum. Sadly, it seemed like X1 has the worse performance of them all...

Most of the performance gains are due to faster RAM/Flash ICs, not the processor.

It does have GPS.
The CPU is also different.
In summary, there are 3 differences:
1. CPU (not much different, I think)
2. GPU (thus can't play 720p smoothly, forget 1080p)
3. Bluetooth (transfer speed is lower)
I own one, and I'm disappointed at the GPU.
So what one does att carry
Thanks. Not getting that one then. Want full power

1. The P1010 weighs maybe 1 - 5 grams less because you don't need to put a card in it.
2. The WiFi-only only has a 16GB internal memory model.
3. No EDGE, 3G, etc.
Where did you guys get the information regarding the weaker proc? The specs at pdadb.net and gsmarena are just the same? O_O
Unless, of course, they haven't modified it yet. O_O
Galaxy Tab WiFi is OMAP3
I just got a Galaxy Tab WiFi and will be returning it tomorrow.
The SoC is an OMAP3 of some kind. The GPU *is* an SGX530, which is significantly slower than the SGX540 on the Samsung C110 SoC. The OMAPs memory controller is also much slower than the C110s, various other OMAP bits are not up-to-spec compared to C110. The Galaxy Tab WiFi is a joke. Buy a nook color instead: save $100 and get a better LCD.
I'm sure that the product spec page for the Galaxy Tab WiFi said "C110 Applications Processor" a few days ago, now it reads "1GHz A8 Cortex Processor" (which isn't even written correctly, should be "Cortex-A8"...). I was suspicious when someone posted that they had inspected a P1010 ROM and it contained all of the TI OMX libraries, but I didn't believe that Samsung would redo the whole BSP for a product destined to sell zero million units.
I was wrong. Guess I'll wait for the Asus Transformer.
It seems that the firmware / Android version isn't upgradable by normal means.
There is no firmware or Android update selection like the Sprint version.
Kies indicates that the firmware is NOT upgradable.
Anyone know what's going on?
I brought mine yesterday
P1010 decode 720P video is fine (smooth) with stock video player

I agree, I haven't seen anything definitive yet that shows it has the weaker CPU. Can any of you smart xda people who has either broken one open (not me, ...yet) or studied the code give a somewhat more definitive answer? I've had mine for 2 weeks now. I'm happy with its performance. But I know I'm going to want to play with the innards down the road. Is it really that much different from the tab phones?
Any update on this? I was going to get a WiFi tab but having second thoughts now...
@victor888 - what app did you use to play the 720p files, RockPlayer?
It is apparently different...

Hi.
I could connect my bluetooth keyboard to my Galaxy Tab P1010 (only WIFI) by an application from the Android Market. This application is called "BlueKeyboard JP". I am using Stock GingerBread Rom.
greetings.
Tested it
Hey there,
I have read a lot about the differences of these Tabs, but I have not seen some real results.
So I just bought both of them... And I compared:
Fazit: the GT-P1000 is really faster then the GT-P1010!
I have made a screenshot of both Tabs. P1010 with Android 2.2.1 and P1000 with Android 2.2 with nothing running then Quadrant.
The results are:
P1000: 1090 Points
P1010: 691 Points
You can feel the differences by browsing, sliding the top bar down and using the back and home button.
I don't have pictures of the Hardwareinfos, but I lookes at them and there are a lot of differences. The CPU is the same. But the GPU is a [email protected] and a [email protected] All sensors are different and other things. [email protected] and [email protected]
I will make pictures and a list of all differences, if someone want's it.
Greetz,
Tillmet
I don't trust in Quadrant benchmark. If you use OCLF in the P1010 the result overpast the 1000 points.
In game I have good performace +-30fps in HD gameloft titles, like Eternal Legacy, Dungeon Hunter, etc. In video performace the P1010 play 720p h.263 very well (test it with the free Big Buck Bunny Movie 720p mp4, the picture quality is awesome) ;no so well with h.264 that need be 480p with a baseline level 3.0 profile.
Yes, is no so powerfull like the P1000 but with the price I am satisfied with it.
Ps. Android System Info show OpenGL 1.1 same that the P1000.

Broadcom® BCM2763 VideoCore® IV Processor Features 1080p Video, 20 Megapixel Photos and 1 Gigapixel Graphics in an Ultra-Low Power 40 Nanometer Design
IRVINE, Calif., Dec 15, 2009 -- Broadcom Corporation (Nasdaq: BRCM), a global leader in semiconductors for wired and wireless communications, today announced its next generation multimedia processor that delivers industry leading performance and lower power in the top multimedia categories for mobile devices. Using 40 nanometer (40nm) CMOS process technology, the new Broadcom® BCM2763 VideoCore® IV multimedia processor provides even higher integration, smaller footprint size and lower power consumption than 65nm designs.
With the higher integration and significant power savings from 40nm CMOS process technology, the BCM2763 multimedia processor features the most advanced mobile high definition (HD) camcorder and video playback, up to 20 megapixel digital camera and photo image processing, and 1 gigapixel 2D/3D graphics rendering for a world-class gaming experience. HD video, 3D games and high resolution 20 megapixel pictures can be displayed at top quality on full-sized HD televisions and monitors using an on-chip industry standard HDMI interface. Additionally, the BCM2763's highly integrated architecture reduces bill-of-materials (BOM) cost to help drive sophisticated multimedia features into more affordable handsets.
Highlights/Key Facts:
-- The breadth and quality of Internet multimedia content is rapidly
improving, with sites such as YouTube now supporting full HD 1080p video
sharing. Consumers are also increasingly using cell phones as their
primary digital camera and camcorder, which is driving demand for higher
resolution and more sophisticated image processing which is currently
only available on advanced standalone camcorders and cameras.
Additionally, newer graphics-oriented user interfaces and mobile games
now require enhanced graphics capabilities.
-- The new Broadcom BCM2763 VideoCore IV multimedia processor enables
best-in-class performance in the following areas:
-- Full HD 1080p camcorder capabilities in a cell phone with
significantly improved quality over current generation handsets
(which generally have VGA or lower resolution camcorders).
-- Up to 20 megapixel digital camera with advanced features such as
multiple shots per second, image stabilization, face and smile
detection and panorama mode.
-- The ability to render mobile games natively at up to 1080p
resolution, which in combination with an on-board HDMI output,
allows a console-quality gaming experience on large screen HDTVs.
-- In addition to providing these capabilities on new handsets, the BCM2763
has improved power savings using a 40nm process without draining the
battery or significantly reducing talk time. Additional ultra-low power
consumption features include:
-- 20% to 50% power reduction in comparison to the prior generation
Videocore III multimedia processor.
-- 4 to 6 hours of 1080p video recording and 8 to 10 hours of mobile
playback, with up to 16 hours of full HD playback over HDMI given
sufficient handset storage.
-- Only 490 mW of chip power is required for 1080p camcorder H.264 High
Profile encoding and only 160 mW for 1080p playback.
-- Only 160 mW of power is required for mobile game graphics
processing, supporting up to 1 gigapixel per second fill rates and
improves graphics performance by a factor of 4x to 6x in comparison
to the prior generation Videocore III multimedia processor.
-- The BCM2763 processor integrates the key functionality and components
needed to drive advanced multimedia capabilities in new handsets. As a
result of this high integration, the BCM2763 enables a lower overall BOM
cost, enabling manufacturers to pass these lower costs on and introduce
advanced features to lower tier phones than previously possible.
-- The BCM2763 integrates the functions of eight chips including GPU
and graphics memory, image signal processing (ISP) and ISP memory,
video processing and video memory, HDMI and USB 2.0. 128MB of LPDDR2
graphics memory is stacked in a single package.
-- The 40nm process enables reduced power, improved performance and
reduced handset board space.
-- Benefiting from an existing VideoCore software code base and legacy
architecture, manufacturers of phones and other consumer electronics
devices can easily add these new VideoCore IV multimedia features to
their products, allowing faster time-to-market.
-- The BCM2763 is currently sampling to early access customers (pricing
available upon request). Handsets utilizing this new 40nm VideoCore IV
multimedia processor technology are expected to reach the market in
2011.

Mi 8 GPS inaccuracy

I just buy xiaomi mi 8 a week ago only for dual GPS signals. But it's accuracy stuck at 16. Even update to miui 10. Any one have better accuracy for mi 8?
i got it below 8 but it didnt last long. its normally at 16. My oneplus 3 was next to it with a 4m while the mi 8 had 16m accuracy. Hopefully its just a bug and will get fixed
Seeing the same thing here. Hoping a future firmware update improves things.
Broadcom always sucks,their GNSS solution from the Global Locate is far from accurary compared to the Qualcomm Atheros solution,even on some older widely used and more stable BCM47531 chips,i can always get just 5-6m accruracy
Try xiaomi.eu miui
Which app are you using?

Gpstest
https://play.google.com/store/apps/details?id=com.android.gpstest
on MIUI 10.8.26 Beta In Germany.
After Screenshot it went down to 4m Accuracy.
Got an update the other day to MIUI 9.5.11.0 and since then, i get 4m accuracy according to "GPS Status" & "GPSTest" indoors.
Guys, I am running the EU ROM (MIUI 10)and my accuracy is 2m during driving, average 28 satelites. On chinish ROM I had only 16m accurcy.
I get the lowest is 1.3~2, but average is 4.
Try switch to GPS only, I.e. without WLAN and Bluetooth assist. I generally get consistent 4m accuracy and sometimes down to 2m.
Just arrive my brand new phone and in spain with the global rom inside a building near a window it has 16 m accuracy and a SNR of 21 aprox.
With and without wifi or bluetooth or anything. Lets hope it gets fixed. : _ (
I bought this phone because of it's theoretical good dual GPS but I'm really disappointed.

Some quick tests with raw measurements data with Global Beta 8.8.21 give me some hope. BTW: Don't believe the accuracy display! What counts only is multiple testing against known points.

That real GPS (not estimated) accuracy and reliability becomes better. Why? Because raw measurement testing with 8.8.21 gives far better results than 8.8.7 especially with pseudorange errors.
if you are interested in GNSS & Android topics:
https://medium.com/@sjbarbeau/dual-frequency-gnss-on-android-devices-152b8826e1c
https://developer.android.com/guide/topics/sensors/gnss
https://insidegnss.epubxp.com/i/960969-mar-apr-2018 (page 48)
Please do not trust in accuracy (estimates) which is displayed in any kind of software, just measure it against public well known points.
just my 5 cents: Mi8 is the first Smartphone with L1/L5 capability so developers have lot of work to bring the 30 cm marketing story to real life and software releases may be delayed because of this complex task.
With the latest MIUI update, the "16 meters" accuracy bug has been fixed.
Has anybody tried the "Global optimized GPS File Replacer" Magisk's module?
Would it make any improvement or is that setting already included on MIUI10 or Xiaomi.eu?
