Hello everybody !
I saw that some phones (iPhone 4, Galaxy note, Samsung omnia7) had a GPS chip which also allows to use Glonass (Russian GPS). I've also seen (while searching for information about this glonass) that having 2 times more geo-localisation satellites would make the GPS lock 3 times faster.
So is it possible to enable glonass support in our phone ?
Thank you for your answers !
which phone model are you referring to?
glonass support starts from the chip itself. so if you unit's support is only GPS, then you can't enable glonass.

I just got the T-Mobile Galaxy tab, and for some reason the GPS is not working at all... It shows the gps sign on the notification bar, but in maps, gps test, and gps status, there is no GPS data!
PLEASE HELP!
Thank you so much in advance,
Michael
i noticed that GPS perf is average indoor, if not below average. it is comparable to HTC Touch Pro, which is quite disappointing.
If you are trying from indoor, try to take it outside. many apps are saying that GPS works better when used with clear sky and i think it performs much better outside.
GPS is not working
I have samsung galaxy tab (sprint), live in Turkey. But GPS is not working both indoor and outdoor. Always searching.
I dont know, ı have to change ROm or not.
Regards.

I would make sure that I'm not using a case that has a magnet or any kind of metal on it. They interfere with radios and especially the GPS.
A couple of months ago I started using a Zenus case which has magnetic buttons. Almost immediately my GPS stopped working. It took me a very long time to figure out the real culprit. I tried rooting, changing some gps related files etc. None worked until one day when after accidentally leaving the cover at home I switched on the GPS - it started working.
Dude, you should update the maps in your galaxy tab. I updated already my maps and gps is runing smooth.

I bought a tab last week in Germany. The gps work fine in Germany, Holland and Belgium. But right now I am in Turkey and here it just keeps "searching" but never gets a location.
I wonder why and what, but I suspect location has something to do with it.
Galaxy tab Sprint gps not working!!!
hello i have a samsung galaxy tab (sprint) i live in malaysia,but when i on the gps it detect my location at hawaii plizz help me!!!
GPS not working
Hi
You definitely need to be outdoor for GPS receiver to obtain signal.
If indoors, you'll get signal if you have tile roof, not steel or concrete.
With a-gps, it might look like you are getting signal but actually, your device is using data to obtain location from cellular towers.
For best and quickest reception, enable your device's location and a-gps. Note, a-gps does not use lot of data, very little.
Hi,
I wonder if it's possible to reprogram i9001 gps module in this way to make glonass network connections possible. SGS III can connect to glonass network and I've read that glonass connection is a software problem. So maybe is's possible to reprogram i9001 module using SGS III software.
THX
I don't think it is possible.
EDIT:It is possible,we must wait for a ROM with glonass support and then we can take filse needed.
I9001 has glonass support,because it has a qualcomm chip inside.It is sad that no rom has glonass support.
Didn't even knew about this network, but i'm really interested right now.
What do you think of this?
http://forum.xda-developers.com/showthread.php?t=1436776
Looking at the table on this link shows that our chipset is capable of running with glonass.
http://ru.wikipedia.org/wiki/Snapdragon
(ours is MSM8255Turbo)
I also think it's possible but we need a developer to help us.
I don't think it's possible because it's probably low-level stuff in baseband firmware. That area is completely proprietary. Same reason why there's no monitor mode for wifi.

Is there any news on this GLONASS for i9001
So many other Samsung's models that has GLONASS support.
does lg p970 has weak GPS receiver
i compared it with samsung mini and samsung pixon 12
each one can catch from 7 up to 11 sats
my phone only can see 2 or 3 and although can't fix it
i have tried different roms and apps like gps status/test + /aid/etc but no way............
is it software problem or that lg phone has weak GPS receiver??!!!!!

This is a common issue... you can try optimizing it with Pimp My ROM or various scripts. Read through the Optimus Black Q&A, Help & Troubleshooting thread and I'm sure you'll find what you're looking for.
The GPS receiver in OB is probably not the best on the market, hovewer it is not as bad as you probably think. In my opinion its weakness is a result of bad software, as some tweaks improve GPS functionality. My OB (on IZS) can fix in less then 30 sec., sometimes even inside the building (close to a window).
There is almost no information on GNSS. It probably has Galileo given that the previous generation of Huawei phones did - but some preview sites say yes others no.
The Broadcomm BCM4775x dual frequency (L1 L5) chips were predicted to lead to smartphones with < 1m GNSS accuracy this year. So far there are only two devices that have been seen in the wild and the only phone is the Exynos (EU and parts of Asia) version of the Samsung S9 Plus. Samsung has not announced or documented it or provided any interface in their software and in the relevant xda thread, the owners have not yet been able to confirm that the L5 signal is accessible .
The previous generation of Huawei phones used the Broadcomm GNSS chip prior to the BCM4775x series. We probably won't know what the p20 pro is using until there is a teardown.
If the leakers are to be believed the only two brands that will not use Snapdragon/ Qualcomm SOCs in their flagship phones this year are Huawei and Samsung. As Broadcomm and Qualcom are archrivals/ probably incompatible, Huawei would seem to be the best hope for dual frequency cm accuracy in a phone this year.
Anyone know any more?
It' a shame for a new SOC but no galileo on Kirin 970

Even if the p20 pro is not Galileo enable, the most important is it dual frequency capable? Coz gps, glonass and beidou are not few also

The binaries on the P20 vendor partition are for BCM4774 as on older phones.
It supports Galileo (you must download LTO from the internet), but is L1-only.

Thanks! When I tried to download the leaked firmware for the p 20, it was 8 Gb unpacked and I had to give up looking inside. Just for the record, if you did the work of finding BCM4774 evidence in the partition (thank you) would you be so kind as to give us a little more detail - even some code snippets if possible (like the xda ers who found and posted firmware evidence for the BCM4775x in the Samsung s9+ - Exynos version).
As you imply and as I understand it, the BCM4774 supports Galileo. But when various people have run GPStest and similar software on various phones, my (limited) understanding is that the phones were getting fixes without an internet connection. I am confused and less informed that I need to be, but do you think that P20 users would need an internet connection to get a Galileo fix? (or are you just saying that it would be a better fix?).
When you say "you must download LTO from the internet" I assume you are referring to the LTO in the following quote from https://www.broadcom.com/products/wireless/gnss-gps-socs :
"In addition to the GNSS receiver chips, Broadcom provides Assisted-GNSS (A-GNSS) and Long Term Orbits (LTO) services. These services are provided from highly reliable cloud-based servers that are fed from a proprietary World-Wide Reference Network (WWRN) stations that collect world-wide GNSS satellite data."

Ifixit now has a teardown which confirms the presence of the BCM4774. I put the comment below in Step 10:
Not highlighted is the GNSS Location Hub BCM4774IUB2G above and to the left of the BCM43596 (green). This means that provided the software/ firmware is amenable, this phone should make use of signals from the Galileo satellites (https://www.broadcom.com/products/wirele... ). This is something that different websites and Huawei itself have been inconsistent in reporting.
I tried GPS Satellites Viewer yesterday evening, and it showed me 3 Galileo Satellites without the download of anything. I tried it in the morning again and now I do not find any Galileo satellites... its strange.

Many apps do not show Gallileo. GPSTest by barbeauDev works.
But it takes a little bit longer until the Gallileo satellites appear in the list.
I have the European version, And it is slow to connect to the GPS, in addition to the "Search for GPS" notification in any application that uses GPS. When it is already connected, the "Location established" notification comes out.
Some help?
Same problem here!
I had the same device with same problem!
Any workaround/fix?
iff you guys are rooted you can try the gps fix module from downloads section. I am on custom rom Asoip and no such problem with gps it is very fast. Also there is an app called Agps on playstore which can re calibrate the Gps and it makes it function faster and it doesnt need root.
A-GPS is only assisted GPS. It's "fake GPS" so to say. Most GPS Status/toolbox apps can "Fix" AGPS by clearing the cache and it will be re-downloaded. However, if you just enable location services for a longer period of time, it should fix itself so to say.
THAT SAID, A-GPS is not precise and is not your location.
Install "GPS Status" from Play Store (either or both) and check the signal strength there.
From what I found... in terms of GPS accuracy...
#1 Samsung Exynos / Huawei HiSilicon (high-end chips, I have not tested lower end Exynos / Kirin)
#2 Snapdragon 600 series (like 670, 675)
#3 Snapdragon 800 series (845, 855 - their signal is trash)
I don't know where MediaTek/Helio stands. But yea, from the devices I tested, this is what I saw. There is the Snapdragon 700 series, not sure how that performs either.
