I've had no problem with CoPilot, it has never jumped to the next lane if that's what you are asking.

Bluetooth GPS Mouse

Yes -- go to the market and download 'Bluetooth GPS Mouse'.

There are two versions -- I'd recommend to use the free version to see if it's working with your receiver. If it works you might purchase the unlimited version in the market or you can order a key file for the free version via Paypal as well (which turns the free version into the unlimited one).

GPS provider works with the same principle. I find it a tiny bit better than GPS mouse.
[Galaxy S I9000 General] herbert1:
I didn't want to pay for something like that and I did not understand why I should give phone call or network access for such an application...

So I've have developed mine:

it' free,

it's open-source (you can verify what it's really doing and you can improve it!),

it just asks for needed permissions.

The application allows to use an external bluetooth GPS on Android devices:

The application starts a service, then connects to a Bluetooth device (NMEA GPS) and creates a mock GPS provider which can be used to replace the internal GPS.

It's also possible to log the external GPS NMEA data in a file on the device.

The app needs the following permissions:

bluetooth and bluetooth admin (connection to the GPS device),

location and mock location (replace the GPS location provider by a new one using the bluetooth GPS device),

write external storage (if you want to log the NMEA data into a file on the sdcard).

It should run on all android devices (2.0 and above) and NMEA bluetooth devices.

I have tested it with a GlobalSat BT-338 bluetooth GPS (SiRF III), a Galaxy S (I9000) and a HTC Sapphire (Froyo CM-6).

It works with Google Maps, Wikitude, GoPenS and my own personal navigation app. It should work with all applications that use Android official location API.

Note: in order to install the app:

enable Settings/Applications/Unknown sources,

enable Settings/Applications/Development/Allow mock locations,

download and install the apk.

right during installation it ask you what you want

after installation it access via menu > more > settings > recording

then you can update the settings to as frequent as you want, or as lax as you want

if you want better path the kind you like when zoomed in, you will need to use max accuracy settings and fastest most frequent updates
[Galaxy S I9000 General] Logicalstep:
I've had major problems with the GPS using Copilot, it was all over the place on at least 5 times on a 180 mile trip...now five times may not sounds like a lot, but if you were driving somewhere you didn;t know you would have found yourself on an adjacent road on three or more occasions and loosing the lock other time, with it taking an unreasonable amount of time to get the lock back.

I had TomTom running on my Blackstone sat right next to the SGS and it was perfect the whole way there and back.

I think people should stop making comments like 'It's working fine' what's the point ...it may be for you, but it certainly isn't for many, many others.

Logicalstep
[Galaxy S I9000 General] AllGamer:
and what do you think i'm comparing it to?

exactly to a Tom Tom device that is more of a miss than hit, at least the Galaxy S works all the time, just configure it to do more sampling per second / minutes

right during installation it ask you what you want

after installation it access via menu > more > settings > recording

then you can update the settings to as frequent as you want, or as lax as you want

after I reset mine google maps worked ...for a day or two.

GPS Test always worked, 6-8 sats locked no problem, but no way would maps get a location, and then go for a drive GPS Test would jump all over the place, I run it side by side with my 3 year old HTC and it's just embarassing how bad it is. I could have easily posted the above photos and mine was crap.
[Galaxy S I9000 General] AllGamer:
as far as i know people in real life drive with a navigation software, not a GPS test software to guide them.

the best thing to do is up the sampling rate in closer proximity and more frequently
[Galaxy S I9000 General] foxbat121:
Exactly. Explain to me again why you posted a screen shot of GPS test to proclaim the GPS works great in the first post?

As far as I know the GPS chip is capable of 2Hz, e.g. 2 readings per second but current driver limits to 1Hz or one sample per second max. Sure you can increase your software polling frequency. But the GPS will only update positions once every second.
[Galaxy S I9000 General] AllGamer:
GPS Test program is what everyone is using to argue about the GPS works or not works

and that is my point, they should use are more realistic software instead

but you can only get through the brick heads with the same bricks else they wont listen

same goes with the google tracker app.

Yep, i'm looking forward for the fine tuning in the new firmwares to come.

Personally, that will just improve the tracks, if i needed to track anything, with less sampling rate thus reducing battery consumption.

more sampling rates in less distance = more battery consumption

accoring to the rumors we should be getting froyo with a ton of fixes in the next week or so
[Galaxy S I9000 General] snaff:
The track app is 'realistic'. Being able to accurately record distance travelled is critical to things like sporting apps and the sgs can't do that as well as other phones.

Agree on the gps test program though, I wish that damn app had never been invented :)
[Galaxy S I9000 General] smazenka:

now im going to flash jm7 or jm8 so im curious what will be the result ;-)

could U recommend which could be better?

EDIT: today wrote me an sgs owner from Slowakia and asked my opinion about gps issue as an expert what im certainly NOT. i v been cutting grass so i turned gpscompassmap app and took a reccord of it unfortunatelly im not able to export the recorded track.

On our property 40 x 100 m i was only cca 5 times behind the borders ;-)

the gps worked quite good.

naturaly it has not recorded exactly my path but to be honest the accuracy is OK for a mobile phone. if U send me howto post the record, im able to show it here.

[Galaxy S I9000 General] igniztion:
Is the GPS usable for navigation?: Yes

Is it a good GPS for navigaion? No, mainly because it somestimes shows you on a parallell road, off/on ramp etc.

Is the GPS usable for tracking a run/bicycle session: No, accuracy is too poor so results of the tracked session are often way off.

Did I hit a max speed of 123 kph on my hybrid bicycle? : No chance in hell, but that's what the GPS reported.
[Galaxy S I9000 General] stan28:
I concur. The GPS on my existing HTC Vogue aka "Touch" was spot on at all times. If it is a firmware issues, we have hope. Otherwise consider it SOL.
[Galaxy S I9000 General] greeced:
I like the OP have fantastic GPS results.

I tested, in another thread, MyTracks for a user that questioned my GPS's accuracy (I've never used MyTracks before).

As stated in the other thread, When I first started out, the GPS positioned me across a side street (less than 20 feet), but quickly corrected itself when I started moving.

I then rounded a corner and stopped at a community mailbox for a few minutes and the GPS 'Bounced' to across the street again, but quickly corrected itself when I started moving again.

I then went around another corner which led me to a path in a park, and the GPS followed me perfectly to within 2 metres. Or at least in my guestimation.

I then sat down on a park bench and it remained completely accurate on my position for the 5 minutes I sat there.

I then got up, continued to follow the path back to my very street, and returned home. The whole walk took approximately 15 minutes or thereabouts.

The circle was very tight around the orange arrow for 99% of the trip, only getting bigger when I entered my house.

So, those 2 little bounces? Well within the optimal range. Even Google's Disclaimer on the MyTracks application says:

"Under optimal conditions the location can be +/- 20 feet (6 meters)."

And my experience was exactly that 100% of the time.

I did the MyTracks test on request, based on certain parameters a poster gave me for doing the test.

I took a 15km trip from a point to home using Navigation and it was flawless.

So in closing, just because your experiencing problems with GPS, doesn't mean everyone should be also experiencing the problem...

If you believe everyone should be having a GPS issue just because you are, then you must also believe that everyone has the 3 button issue as well. I don't. Mine works well (after I returned a non-working one with one that works at a Bell Store.)

I'm wondering if the original OP, like me, has had the 3 button thing working from the get go. I'm also wondering if those who have GPS issues have their 3 button thing originally disabled.

Either way, mine works and I'm happy with it.

P.S., I won't be posting any tracks for you to see because:

1. I don't need to prove it to you. If you don't believe me, thats not my problem.

2. If I had a problem with GPS like others, I wouldn't sit on my hands and say it works great for no reason.

3. I don't need to tell you all where I live.
[Galaxy S I9000 General] zorxd:
The thing is, with my HTC Hero (as well as my father's Milestone) Google Navigation never jumps to the next road. With the Galaxy S, it happens. So the problem can't be with Google Navigation.
[Galaxy S I9000 General] mstrandbo:
I thought I didn't have a GPS issue, but when I started using SportyPal regularly I noticed I did indeed have. Running JM2.

The GPS gets a fix pretty quick, GPS test says I have 5-10m accuracy.

But when running SportyPal, and looking at the screen, I can see the GPS icon in the notification drawer, then suddenly my speed plummets to 0 and the GPS icon disappears. I keep walking, and some seconds later the GPS icon is back, trying to get a fix. It does get a fix pretty quick, SportyPal reports my speed as 20-30km/h (while walking), then it normalizes for a bit, then the GPS icon disappears again, and it's starts again.

This makes my path on SportyPal very erradic and inaccurate.. It's accurate when I have the fix ofc :p But that doesn't last long since it's going on and off.
[Galaxy S I9000 General] AllGamer:
this is absolutely true, i too don't sit quiet when there's a problem or I think there is a problem that needs a solution.

like unlocking the phone for example, i put up the $75 bounty up front and created the original unlocking topic for everyone's benefit.

i've posted many topics *****ing about problem with Kies, Bell, and many other minor problems i've encountered with the phone, and anytime i encounter a problem i go find a solution and post it in the forum to share with everybody.

What I have noticed is that most of the people having trouble with the GPS are mostly using the International model, and the people on AT&T

People on the Canadian model, Brazil, Korea model seems to have less problem with the GPS

when i first started with the SGS i did have a UK model until i switched to the Canadian model

but even the UK model one worked better after swapping the ROM

from my point of view it's definitely a software customization issue.

playing with the accuracy, and sampling rate settings on the phone and Apps it gives better result

another thing about the GPS is that sometimes it will lock up, if left on for looooooooong period of times

in which case, all you need to do is to turn off the phone and turn it back on, then it works again.

This is nothing compared to my old HTC phones, which required much more effort to get the GPS working straight, or working at all.

With the SGS GPS when i stop at a intersection it is accurate enough to keep me on the same side of the street and not on the opposite side of the intersection, or on the side street

with the HTC phone using the GPS when i stop at an intersection, the thing goes crazy it turns round and round and round, until i continue driving, it will think i'm in the wrong side of the street and give me another set of directions, which is horrible when you are driving in an area unknown.

That is a major issue, yet nobody seemed to care much about the GPS issue back then, this is one major reason why i shopped for a new phone which happens to be this current phone.

in Fin, yes i can relate to what people are saying when they have trouble with SGS, but not all SGS units are defective as people makes it out to believe.
[Galaxy S I9000 General] AllGamer:
I'm just glad my SGS is working as expected, as my Car's speedo is dead, so i depend on the SGS in a daily basis to know how fast i'm going.

there are many areas where you have to road side radar that shows you the speed of the car when you come in to range, and so far the speed detected vs. the SGS GPS reported speed are spot on.

accuracy might be a few meter off, but is accurate enough to navigate the small streets without it thinking i'm on another street
[Galaxy S I9000 General] Oletros:
U have had an HTC Hero and a Nexus One and most of my friends have Magic, Legend, Nexus or Desire phones.

GPS on all phones works as intended, on SGS is horrible
[Galaxy S I9000 General] greeced:
Just a side note:... I had Garmin Mobile XT installed, with the latest maps on my previous HTC Touch Diamond, and the thing took forever to lock on to satellites, and consequently my location... 5 minutes at least (aGPS or no aGPS)... much longer than the 10-20 secs (max) I'm experiencing with this thing.

I've tried Google Maps, Google Navigation, Google Earth, and now Google MyTracks, and all work flawlessly and report within 10 metres 100% of the time, and it reports within 5 metres in optimal conditions (clear sky, no clouds etc).

I've never had any issues with this thing, crossing fingers.

For those that say Garmin GPS's "snap" to the proper road or location, and you'll notice that, the snapping thing is false. You only notice the snapping thing because of the sample rate.

Yes you notice this more on ramps, because your driving in a straight line, it will take a sampling of your location and it will continue showing you travelling along the same direction (not road) until the next sampling. But if you get on a ramp between samplings, you'll notice the "snap" you all refer to. Not because the GPS is doing anything different, but its updating your location based on the next sampling received.

The only reason why it follows you around the ramp more accurately, is because you are generally going much slower than the straight line route, so the sampling appears much quicker compared to distance travelled.

At least, like yours, is my guess of what happens. Only Garmin, or any gps company's engineers/programmers know exactly what it does.

Do I use my GPS on my phone very often? In real world use no... but I have tested it extensively for giggles, and it works great.

But on long trips I'll stick with my Garmin 255WT. Its what it was designed to do, and nothing else. So regardless of whether my SGS works flawlessly or not (which it does), I still wouldn't use it for trips, because much more technology (faster routes and the like) is better implemented in their system, than what is currently available for any phone.

At least thats my opinion.

Take care.

Samsung Support told me today that it was a localising problem of GPS settings especially with Google Maps and will be fixed in the next firmware. If you use any navigation software, you would have to make the settings there somehow. :confused: They could'nt explain it any further.

Would be a reason for some people having less problems with GPS, depending on location. But I'm a bit sceptical about the relation of the bugfix to Google Maps.

Yes I know...Lots of users very satisfied with their Gs gps experience and many others unsatisfied....and many others just confused...

Nothing better then some video clips to DEMONSTRATE in motion picture (of course) what many users have been already talking about.

Solutions (or methods if you prefer), that are working for me and many other Galaxy S users, in order to improve the GS GPS navigation experience, in this case, turn-by-turn voice guided car navigation. Tested only with offline navigation programs like iGo, Sygic, Navigon, CoPilot ,etc.

Tomtom and Garmin AFAIK, are not available for Android yet.

Not tested with online nav. apps. like Google maps ( wich is not available or not working properly in many countries). Furthermore online navigation leads to roaming costs when used Abroad.

Video 1 is about the method that can be applied in almost any Android device and is specially interesting for those using those devices with no build-in gps receiver:

http://www.youtube.com/watch?v=BM2gm5DAOjM

Video 2 shows the SGS running navigation software like Navigon (my favourite remains iGo Motonav wich I used on the first video), using this time the INTERNAL gps receiver with some assist (pre-downloaded ephemeris data) using some nice software.

I removed some parts of this video ( long waiting at stop lights, or too much background noise) and in this way reducing video size and upload time...:

http://www.youtube.com/watch?v=p6QnNMxuCig

I call this methods in fact solutions, for those who use gps also abroad or go online only through WIFI, that means no data account and/or dont want to be dependable on wireless/cellular networks (a-gps through Cellular towers for instance)

See videos for more details and conclusions.

And please dont mind my english on tape, it was tough to drive, navigate, demonstrate, handle the video cam, concentrate on the english that is not my first language and it's a little rusty, all at the same time.

More conclusions to follow, I just want to post this first...

My thanks to the 3rd party developers off some nice apps. like:

-Bluetooth Gps Mouse Unlimited

-Gps Status

-Turbo Gps

-Gps Finder

-Gps Test

Ps. - If you are 100% satisfied with you gs gps experience, and you think this thread is irrelevant, good for you!

Instead of placing unsubstanciated remarks or 3rd party information, just place your video! No words or pics, just motion picture...there are already enough "GPS" confusion in this and many other forums.

Please feel free to place your self-made gps videos here...

[Galaxy S I9000 General] distortedloop:
Thanks for posting the videos. Your English is just fine in them. ;)

I really think you should rename this thread to indicate that you don't really have a "fix" for the internal GPS system, but suggestions for alternate 3rd party hardware device that replaces the internal unit.

Many people may see this topic title and get excited that you've found a way to make the internal SGS GPS acceptable, only to be disappointed that nothing you've shown in either video does that.

Maybe you should name it "GPS Video Thread (using a GPS mouse with SGS and tips for hot-starting your internal GPS)" or something that better describes what you're showing.

Thanks again for the videos, though, I saw several interesting GPS related apps on your phone that I hadn't seen before.
[Galaxy S I9000 General] betoNL:
Thanks for your reaction.

I think I understand the confusion but the first "method" on the first video has really nothing to do with do with how fast that satellite fix happened on the 2nd video when I started the Gps status app.

The 2 methods (not fixes) are not related:

The bluetooth GPS mouse app. have an option "Keep GPS disabled" wich I use, so all data during navigation goes to the external gps device.

In the second video when i first started GPS Status app., I was parked in an open area, some kilometers away from the living area with no buildings, trees etc. and earlier that day ( lesst than 4 hours before) I did use Gps Status so the "data"(Ephemeris) was very recent an all these factors together lead to that very fast fix during that hot start.

If you noticed, at the end of the second video, I parked the car, Closed Navigon software, and started Gps Status app. again: The satellite fix took a little longer and it was viewing less satellites.

That's because I was back to a "living"area with a big building behind me and on the right and some trees in front

You can run some tests yourself, just using the Gps Status app. in different enviromments:

Go OUTSIDE, enable the gps, start Gps Status app. go to setting/ Gps&sensors/ manage Agps state/ thn reset and then download data ( you need internet connection).

Just patiently wait for that satellite lock ( it can take from 1 to 3 minutes or more depending on the environmet); If you are surrounded by buildings it can take longer. Then close application and the gps, move to a more open area with no buildings, etc., open Gps, start Gps status app(you can even disable internet connection) and you will see how fast that lock will be.

If you are always online (data account) just reset and upload data regularly using the Gps status app. while gps is on (and always outside of course). You can also set Gps Status to auto-download data on an hourly basis..for instance during a long trip...

Run these tests on these conditions and you will see that the internal gps receiver on the gs doesnt need ANY fix, just some assist, provided by apps such as Gps Status

Once again, these are not "fixes" but "methods"

Have fun

Edit: Of course I have to run more tests, and of course the internal gps is no sirfstarIII equivalent,

but I already noticed that it's better the the ones on the Nokias, Nexus and more...
