Huawei kirin 980 created his own dual gps chip
It seems to be something better than broadcom.
GPS (L1 + L5 dual band) / AGPS / Glonass / BeiDou / Galileo (E1 + E5a dual band) / QZSS (L1 + L5 dual band).
Huawei mate 20 and mate 20 pro have dual gps.
Using GPSTest it seems Dual-frequency is still not in use. Maybe it is the same issue as the Xiaomi Mi 8 did when it was released.

The most time my accuracy is about 4m. That`s not even better as on my Galaxy S7
So far I've not been particularly impressed with it's accuracy. My Mate 10 pro before that was very hit and miss as well. Granted, I live in a big city, but my wife's iPhone 7 has no such issues... Not Huawei's strong point it seems.
It says accuracy can reach up to 30 cm, which means lane level accuracy. Driving in Kuala Lumpur will be fun
It's as accurate as I need it to be and it's there when I need it.
4-5m is about as much as you realistically need IMHO (unless you're using it to program a cruise missile for a clinical strike).
If you cant find what you're looking for when you're within 4-5 metres then maybe you need to go to Specsavers (other opticians are available)

I agree. As much as I like it to be as accurate as possible, I'm on a consumer device paying consumer money.
The worst that usually happens to me is Google thinks I'm in the shop next door.
I can deal with that tbh and I have no desire for Huwaei (or any other manufacturer) to spend several million £/$ just to get my GPS down to my EXACT location.
The last thing we need is these phones being even more expensive
If it works better than my Note 9 that will be good enough. Can't even walk around city centres, it can't decide which way it's pointing or what street I am on haha. Android phones have never served me well for GPS. In a car they're fine though.
I have not seen improvet accuracy mentioned in meter but (subjectively) I get the opinion that it is better to nail my position even if I'm inside a house etc...
My gripe is the accuracy and precision when using the smartphone GPS in big cities with skyscrapers, particularly when walking. The blue dot on Google Maps will literally jump around 20 to 40 meters for no obvious reason. This has happened to me numerous times on Samsung and late model Huawei phones. .
Just last night I was in Manhattan, New York City. I came out of the museum and found myself in a freezing rain downpour. I used my Huawei Mate 9 to make a beeline towards the GPS indicated nearest subway station. Long story short, I spent 15 minutes going in circles as the blue dot kept changing locations. While GPS got me in the neighborhood it did not come close to nailing the location of the subway entrance. I still have to do frustrating excess walking & backtracking to find the subway entrance.
This has happened to me in EVERY city with skyscrapers that I’ve used GPS. Doubly frustrating when the Uber driver and I am very close… But not close enough to recognize we are near each other. And yes, I have “calibrated“ my compass multiple times. Have even refreshed A-GPS data. How about it Huawei? Samsung? Broadcom? What can be done about this? Buy a Garmin?

Great idea! Have Huawei include a world atlas (book form of course) with every phone sold to make up for GPS shortcomings!

Just curious… What data did you see that leads you to the conclusion that Huawei’s implementation of dual frequency GPS “seems to be better than Broadcom”. Or were you just trying to get that conversational ball rolling?
By the way… Great topic.

Better because it's gps from huawei.
And not an external GPS.
So support should be better
Xiaomi mi8 is gps broadcom
and he had to rely on support from broadcom.
The last update of the android in huawei mate 20
improves gps accuracy in Google maps.

Not true. The Mate 20 Pro still doesn't use L5 and E5 bands, therefore the phone has the same level of accuracy (up to 3-5 meters) like any other device, rather than 10-50 centimeters (something dual band GPS should be able to do).

Yes, it's true that android needs a patch
from huawei mate 20/20 pro.
Currently, l5 does not work.
But the last update EMUI 9.0.0.142 from huawei
improves gps accuracy in Google maps.
https://www.gsmarena.com/huawei_mat...to_quality_biometric_unlocking-news-34614.php
I have no idea or last update
supports l5.
And if you do not have to wait for a correction.
The same was with xiaomi mi8.

142/146 update did not bring L5 support ,accuracy is the same as before: good, but nowhere near cm levels. So the L5/E5 update is still necessary, but the current climate around Huawei in the West is anything but ideal so who knows.
When dialing in the target for your cruise missile, to make up for jittery GPS just aim a little in front of your target to get maximum splash damage. If you need 'per window' accuracy use Hi-Vision instead, at the last second you will get a notification about helpful suggestions for storm shutters and such on Amazon.

I prefer to use a cluster of consumer devices and then aggregate the GPS positions to improve the accuracy:highfive:

Hi, maybe a missed something, but with "cm" do you mean CyanogenMod on Mate 20 Pro?
I've an S7 Edge but I'm very unhappy about GPS, I'm looking for a smartphone with a better accuracy on localization (mine often it's wrong of ~10 meters).
with my M20P i get indoor >20 satellites, display shows 4m accuracy.

Is HD2 better than standard REAL CAR NAVIGATION ??
I need to go to UK next week and will need a good navigation.
I will start from Poland so 2000km will be done with this nav.
What is better HD2 with NAV or REAL NAVIGATION (Mio, garmin etc.) ?
***sorry for my language - still learning ***
in my country, Real Navigation is better, our Google Maps is not updated
TomTom on my HD2 works like a charm. I drive every year from The Netherlands to France, Spain, Italy and back during the hollidays. Just make sure you have updated maps.
I've used Garmin XT on my previous PPC as well as on my HD2. This works as well as any REAL CAR NAVIGATION system. However, please make sure you have updated maps..
Where can one get satnav software for the HD2? Google maps is ok but when I'm driving I prefer voice guidance from something like TomTom
Load an Android build and Google maps with Google Navigation, (Voice prompts), is brilliant here in the USA.
Bing works very nicely too in Navigation mode but I have experienced it locking up on me more than once so the battery had to be pulled. I've heard that if I had been more patient it would come back. That's OK when you are on a long haul trip but in a city you could miss your turn easily.
So what you think ?
I'm not suggesting any maps becouse AutoMapa (similar to TomTom) works perfect for me:
- vice commands
- quick fix
- and many more
Is HD2 is better than a cheap NAV (40 $ - 100 $)
I am worry about technical issues.
You know ... 30 hours ON , memory lacks , battery heating , and other.
Inside Poland works great but still thinking about Garmin Nüvi 1200T (95$ - with TMC).
Please help :
HD2 with Automapa or Garmin Nüvi 1200T (with TMC) ???
Consider this that i'm not happy to spend additional 100$ , but still
looking for safety because i'm going with family so mayby i will need to
spend this 100$.

not true. i have been using Igo8, mapking and garmin Que on HD & HD2 to Malaysia from Singapore. i just got back from Genting & Sunway lagoon 2 days ago using HD2, even had Yong Tau Fu at Ampang. Comparing to my brother who had a dedicated Garmin GPS on board and made a few wrong turns, i feel that HD2 GPS is as good as dedicated GPS device.
^
I mean, Garmin Mobile XT on HD2 is good no doubt, but then, MalFreeMaps has 3D buildings, but I cant benefit it cause GMXT doesnt support it..
MalSingMaps has Junction View/Lane Assists, and GMXT cant support..

1. na dlugiej trasie startuj zawsze z naładowanym HD2
(on the long route, always start with fullly loaded HD2)
2. Używaj ładowarki z wyjściem 1A (075A to minimum)
(use the car charger with power output of 1A, 0,75a as the minimum
3. Przyciemnij ekran, wyłacz autoregulację jasności
(dim the screen, block auto dimming)
po spełnieniu 1, 2, 3, HD2 grzeje się o wiele mniej, jesli w ogóle
(when 1,2 and 3 are met, HD2 heats significantly slower, if at all)
na trasę polecam iGo8.3 lub TomToma (autoMapa zwłaszcza wersje 6.x mają śmieszne algorytmy wyznaczania tras)
(for this route I'd suggest to use iGo8.3 or Tomtom (as AM routes thruogh some funny points, especially since 6.x version)
robiłem tą trasę wielokrotnie bez problemów... aby się nie krzaczyło, wyznacz osobno trasę do promu/eurotunelu, i potem osobno juz w Anglii.
(for safety, make two separate routes, one to ferry/Eurotunel, and the second one in UK)
Thanks for reply.
This info was really helpfull.
*** Dzięki za informacje *** Thanks for your help
Please close.
No. Even though Google maps itself is better in my area of the U.S., the cell signal will drop just when you need it the most. I drive professionally, and use a 5" TomTom. I use the HD2 as a backup.
One thing it DOES do better, is pinch zoom and that is way nice to see the route ahead. I can move the map around and zoom in and out easy. The TomTom, no way, it is very hard to zoom and drag the map. Too slow and clumsy.
I use both, but if I had to pick one it would be the TomTom.
hope this helps
Oh I wish Garmin had a new version just for the HD2
To my opinion HD2 is a better choice. I have 3 navigation systems on my Leo - Garmin XT with Geotrade map, iGO with Teleatlas map and Navigon with Navteq Q4 map. They are all excellent apps with great road coverage of the maps which are OFFLINE maps. The advantage is that you can choose wich one to get and there is no need for Internet connection which is the case with Google maps. The screen is big enough. The only draw back is the battery drain but you can always buy a car charger.
I consider my hd2 is a better choice, I run IGO8 and its more accurate, faster,and the overall exerience is sweeter than my off the shelf Navman. The navman is now relegated to the old tech box
Travel
OK,
For me the HD2 is definately the better choice.
However, stay away from google maps, in the city of Lodz,
which I recently visited, it did not show a street, despite
it being there for a few years already.
You can use automapa, which works very well on HD2,
together with the "NaviComputer" software that can be
found on this forum.
I used automapa when driving Germany-Poland and back.
It worked very well.
I used NaviComputer to go through a city (on foot), because it's more
like a map, only with the benefit that you know EXACTLY where
you are at any point. It will know house-numbers quite often better
compared to traditional Navigation.
Powodzenia,
Pozdrawiam,
Tom
P.S.: I have a USB radio, so not only does it navigate, but the radio charges it AND it plays my favorite music. SWEET.
If you don't have that kind of radio, you can just buy the charger. Every MediaMarkt or RTVAGD should have it.
I would have but I couldn't get a good enough signal from the GPS which is a real shame it would be real patchy and didn't update within enough time meaning I would miss my turn then it will say turn when I was about 100 Yards from the corner.
But that could just be down to ROM or Radio but oh well. Try it a few times but you can save some money and use it
I've seen alot of posts of people getting their new SGS2, but I haven't seen any GPS results. I expect it to be the same as the international, but has anyone used gps test or gps status to see how well gps works?

Nice, thanks for the laughs Attn1 - and good to see you posting over here.
I gotta agree with shad0wf0x though - I'd like to get some general impressions about the GPS on this device, as I want one that works, and my wife's Cappy is absolutely junk in this regard.
Mine insta locks with 3 sats and will pick 4 more up in less than ~15 sec

Works great, good as my iPhone's did. The Infuse GPS was awful and it really pissed me off when I was foursquaring, but this phone does it PERFECTLY.
Mine locked on in less than 5 seconds and it is a cloudy rainy day here.

well I didn't wait, i got 3 sats in 10 seconds or so, got another 4 or so in under 30 seconds, did the update agps in gps test and got 11 right away strong locks (41+ indoors). GPS looks good to me.
Got a fix on 8 out of 9 sats in my living room in under 5 seconds.

Really? I was at a Waffle House in Atlanta, GA and my GPS said I was in Chattanooga, TN and no matter what I did it kept locking on there.
I'd be using Google Navigation and it would take like 2 minutes to lock before it started navigating.
I'll echo the good user experience of most of these folks -
Wife tried hers on the way home - google nav got an accurate lock in about 15 seconds.
I waited till i got home and installed gps status - 4 sats within 5 seconds, 7 at 12 second first location fix, inside my metal roofed house on an overcast day. Had 11 sats by about 30 seconds or so - but never reported better than a 25m accuracy...not sure what's up with that. Did not clear or redownload agps data.
Mine just took about 7 seconds to get a lock after opening up Maps fresh and took about 15 seconds burrowed inside my downstairs apartment. Very good compared to my old Captivate and even faster than my stock Infuse - and MUCH better than my Infused version on 2.2.3 (no disrespect to gtg though, it was as good as it could get I think).
GPS is definitely wayyy better than the Captivate ever was!! I got lock within 10 seconds... I'm not disappointed by this phone at all..

Various Reviews. The Exynos APU also have a GPS baseband circuit built-in but Samsung decided to use an expensive dedicate GPS chip instead. I think the reputation of the poor GPS in original Galaxy S forced Samsung to do this.

Exactly. The SoC does have integrated GPS functionality, but Sammy chose not to use it. In fact, as you probably know, it's been rumored since the i9100 launched that the brand new SirFStar IV chip was in the Galaxy S2. I'm sure the SoC solution worked, but seeing as "gps issues" was probably one of the biggest complaints against the old Galaxy S, and in such a thin phone there isn't tons of extra space to put a huge antenna, they probably wanted to put the best GPS chip in that they could find!
The GS2 will never rival the reception of a dedicated GPS unit with a big ol' ceramic patch antenna, but it should work about as well as is possible with such a small antenna. At least, that's the hope.
PS, this is supposedly the GPS chip in the GS2. Which interestingly enough actually contains it's own 109 MHz ARM7 CPU. Normally GPS is handled by a combination of the baseband and the SoC, so it's gonna be interesting to see what sort of tweaks and upgrades will be available in the future by virtue of having a dedicated GPS chip.
And non sequitur for those interested, that means there's an ARM core in the baseband, another in the GPS, and 2 in the SoC. Quite a few cores for a tiny little device...
Could someone help me ... I need to identify what is the phone with gps (hardware) with android system (no matter the version). Could someone help me? I'm not talking about software .... I need a technical report (antenna, number of channels, chipset, .....)
Sorry for my english...
I guess those that support GLONASS as well as GPS. My A510 does that and I really notice a difference between that and all those GPS only device I have had before. Where I am it usually have 2-5 more satellites in view, and locks to 1-3 more than GPS only devices. Therefore it startup quicker and accuracy is also a few meters better.
with new phones coming out ask the time, it is almost impressive to say while is best. However, from my experience, Motorola phones are, in general, fairly good. Samsung GPS are absolutely atrocious -- so bad that if you use the GPS a lot, as I'd guess you do, it renders the phone almost unuseable.
Hi All,
could anyone share their experience about the GPS performance of the xperia tablet?
I'm considering buying this tablet but I definitely need a quick GPS and I was really discouraged after reading this:
reviews.cnet.com/tablets/sony-xperia-tablet-s/
I own a tablet s and the GPS fix is really slow (my girlfriend has got a samsung galaxy tab 8.9 and under the same conditions she always has a way better and quicker fix than my tablet s).
I really do not understand why the GPS/navigation compartment was not developed better: Sony put a lot of attention into making the tablet splash proof, small and light (all nice features if you want to take the tablet out for a hike) but I have the strong impression that the GPS performance is really lacking: could you please share your thoughts?
What's your experiance indoor/outdoor?
Thanks in advance
Wish you all well

The GPS function of most all tablets (and phones) is not designed to be nor meant to be fast and accurate. The intended function of a tablet's GPS is to approximate its location so apps can provide the user with localized search results and geographically targeted articles and advertisments.
There are many apps that use a tablet's GPS for navigation, but almost every one of those apps fail to perform with any great satisfaction. Apps like Google Maps are fairly accurate in determining a tablet's location, but only if the tablet is relatively motionless for several seconds. If the tablet is not motionless, like being in a moving vehicle, Google Maps will/can not quickly and accurately determine the tablet's location.
If you truly need fast and accurate navigational information, you will need to use a "real" GPS device. I use and recommend Garmin.

Hi there,
Thanks for your reply.
I understand your point even if I do not agree with it (as the GPS is listed under the specs and as I have paid for it, then I would expect it to work ok).
You said the aim of tablet gps is to only give an approximate fix but my sony tablet s has troubles even reaching that steady/motionless fix (meaning that sometimes I wait and wait but I cannot get a solid fix. It works more or less ok only when there are ideal situations such as no buildings/trees around and you are on a flat terrain -i.e. no mountains-).
I would not want to use it for navigation in a car but I find it useful having some help when I'm discovering new cities as a tourist on foot. As I'm walking by slowly, reading wikipedia references, I would like to at least have a quick fix on the map that tells me where I am.
As I said, I have tested the galaxy tab 8.9 gps (and also a galaxy tab 2 10.1) and they beat the sony tablet gps hands down: in a narrow street with tall buildings they obtained the fix almost instantly while the tablet s could not (I remained in the same spot motionless for over a minute). All devices were using only the GPS in order to obtain the fix (so no 3g/4g).
I had the same (bad) experience "against" an iPad: basically I was invited to an open air exhibition where you had to use your tablet (be it Android or Apple) to tour the virtual musuem that was setup in an open air space. The open air location was the park of a villa, so not huge (let's say 4 times a soccer field) and with lots of time spent standing still in the same place in order to have a look at the virtual attractions. I was standing by the curator of the exhibition who had an iPad: he was able to get a GPS fix almost instantly and could start talking about the virtual attractions, while my tablet s never actually got a good fix (basically they asked us to install an app that was feeding us content based on our GPS location so, for instance, if we were in front of a bust (which had fixed GPS coordinates), then we were supposed to see the curator or other members explaining the history of the bust etc through an augmented reality app). In the end I was quite embarassed/annoyed to keep using my tablet so I joined another visitor and we used her tablet. The compass was/is also not accurate (I removed the tablet from the case in order to make sure there was no magnetic interference).
What I would be interested in for this thread are direct feedabcks from xperia tablet s users with real life situations: I'm quite afraid that all the alluminium that was used for the back cover/chassis of the xperia tablet might hamper the GPS funcionality (even more than in the tablet s...). Almost the same thing happened with the Asus transformer.
Thanks again for having taken the time to share your thoughts
wish you well

Hi, so did you ever get the Sony Xperia Tablet S? I have the SGPT123US/S with 4.0.3 rooted I bought last December 2012.
As for the GPS...lets just say it works....but it's not the best. The unit I have in my 2012 Toyota Highlander works a lot better.
Let me know what you did and how it works for you.
Never had issues with gps at all as long i have internet connection, did't really try without internet.
tested outside works fast, inside takes forever.

Hi there,
thanks for sharing your experience.
In the end I went for a Galaxy Note 10.1 and I'm really satisfied. Aside from the screen (Sony screens with true black technology are slightly better in my opinion), I think the note 10.1 is a very good tablet. I'm happy with the change (and the GPS in the note is lightning fast and accurate: it is able to pick up your position even inside buildings, trains or buses...a true life saver when you are stranded in a city you do not know).
wish you well

Good choice. I may have gone for a different tablet if not for sony points I used to get this one. I would still rate this xperia tablet s in the top 3 tablets in its class and that were available last december 2012. I would also agree this sony gps works a bit better with internet, but it still works without and probabaly good enough for what it gets used for, which is not turn by turn directions in my case. But you probably made a wise choice all things considered. This xperia tablet s has some great features but if you weigh in the sony proprietary adapter plug, somewhat odd shaped kluge of a case, and overpriced accessories ....the galaxy was probably a better choice.
Take care.....
What about the dual channel GPS?
Do you feel any differences comparing to your previous phone?
A few quick tests over the past day or so have shown it to be a major step up from my Oneplus6 and the compass has been spot on

Dual frequency GPS was a consideration to my purchase of this phone - hoping for great things, completely unknown to reality.
I work in the CBD and drive out of an underground car park. With my Samsung S8 and later a work provided Motorola g5s Plus it took a small but considerable amount of time for Google Maps to pick up where I was exactly - sometimes would pick me up in another street, adjusting until it got its lock on me.
Using the Mate 20 Pro, OMG.... I am stoked! Just as I'm coming out of the car park (maybe 2 or so metres before actual sight of sky) Google Maps has an accurate pin of where I am. This invaluable (apart from Maps telling me best way home traffic wise immediately) as I use a Vehicle Log Book which obviously relies on GPS as well. Normally i've been at least 1km away before the Log Book app recognised I was actually driving in the CBD.
Absolutely love this dual frequency GPS as I assume this is what has made picking up my location in CBD enormously quicker.

Can you give us an update on your sentiment towards the GPS accuracy and precision? I’m very curious if you have to contend with a lot of skyscrapers, like in Manhattan New York. I have also been at intersections in Japan where it instead of a four way intersection you’ll have an eight way intersection and if you don’t have absolute accuracy with your GPS you will go down the wrong road. What are your thoughts?

I watched the video, sorry to say (and also sad to know) that dual GPS is not yet enabled. you need to see a single GPS satellite outputting two frequencies namely L1 and L5 (CF), or to put it in another way, the app should show two similar IDs for the respective GNSS.
I remember someone saying that they did see L5/E5 enabled in 9.0.0.171.
If there is a reliability/lock improvement via Google Maps, it's because of 9.0.0.146 update.
L5/E5 features and benefits over L1:
1) Improved ionospheric correction
2) Signal redundancy
3) Improved signal accuracy
4) Improved interference rejection
5) L5 is, to date, the most advanced civilian GPS signal
6) It transmits at a higher power than current civil GPS signals --> RELIABILITY
7) Has a wider bandwidth: Its lower frequency may also enhance reception for indoor users

Dual frequency GPS test
I used this app for testing the dual frequency GPS:
Geo++ RINEX Logger
https://play.google.com/store/apps/details?id=de.geopp.rinexlogger
and apparently it shows the GPS module to synch with:
GPS L5
GALILEO E5a

I tried this on 146, results are the same. But I still feel Dual GPS is not enabled fully.
notice that there is not even a single Multipath L5/E5 lock although they are detected. Red bars should appear for all four of them. Also we need to wait for another 4-5 years to be able to see ~30 cm accuracy because currently a handful of satellites are offering L5/E5 and by 2022 it is predicted to rise to ~24 satellites.
btw cycle slips gives an estimate of GPS accuracy because L5 signal power is around 3dB more than L1 and chances of phase lock disconnections due to cloud/rain/trees/buildings etc will be relatively less as compared to L1.
Multipath is to do with GPS reliability: if you are getting quick GPS locks inside your house while you are away from window, then you must be thanking L5 multipath signals..
Also, trade-off for accuracy is reliability, not the other way round: this means that the good will not get that better but, importantly, the bad will not get worse..

Multipath: https://www.e-education.psu.edu/geog862/node/1721
Probably in my case the app doesn't detect multipath just because I'm currently in a house located in a flat country with open sky and no buildings higher than 6 meters and nearer than 50 meters in the surroundings.

actually that should have been the case since multipath is situational
but L1 Multipath is functioning?
could someone with 171 test GPS because I read somewhere that GPSTest app is showing both L1 and L5 CF for some of the GNSSs in 171.

Nothing showing in the CF column in 171.

I also read Sean Barbeau’s article on dual frequency GPS with great anticipation. From all indications, dual frequency GPS on smart phones from a real world USE perspective has been a total bust to date. Although companies like Xiaomi and Huawei trumpeted this as a great achievement, no one has realized any practical decimeter-level accuracy benefit. To be fair, there are possibly faster lock times reported but not substantiated..
What an unfortunate situation. I double checked the Xiaomi forums to ensure there has not been any tremendous development as far as 30 cm accuracy. After all, they’ve had nearly a year to work out any kinks. As of this date there has not been anything close to 30 cm accuracy substantiated.
