tonight becomes my night to learn the sdk and adb :D

got everything going right but i just wanted check if that 3rd file the secgps is just a backup or needs to be copied over as well? basically it says i dont have a gps directory to copy the file into. man this stuff reminds me when i was 8 playing around in dos shell....goood times...good times;)

had to completly reflash my phone due a fault of my own. so anyways here my cog2.2 with tracks as is no changes. pretty bad stuff. if i had to explain midway down the highway i simply decided to try to stick my phone out my window while i drove. not a very effective way to navigate lol!

will apply fix later and see if there are any changes
[Captivate Android Development] askpcguy:
What about the gpsconf file then? When I tried the i9000 ROM I had better GPS performance and noticed it using the supl.google.com server.

I restored my previous ROM and in LbsTestMode switched to the supl.google.com server, I still saw pretty quick initial locks.

I even tried testing against a friend's JF6 Captivate outdoors, I had a lock much quicker than his. I was able to location lock in Google Maps before his Lbstest mode obtained a lock.

He switched to supl.google.com and rebooted, same results as before. I had a lock faster.
[Captivate Android Development] ceebz:
Exactly. Some people seem to be confused on what exactly is wrong with the captivate's GPS. Lots of people can get locks when stationary, but the accuracy while in motion is a whole other story.
[Captivate Android Development] DJNgoma:
Experiencining the same, will test if it is the fact with NDrive as well.
[Captivate Android Development] ajayendra:
Tested gps and nav while driving to work...

With default SUPL settings w 7275, it was bad but changing to SUPL.google.com and 7276 inproved the performance, but still gps is sort of unreliable. Tested in clear sky and am pretty sure its gonna screw up on a cloudy day.
[Captivate Android Development] mattbeau:
This is what I do

For me all I did was flash jf6 then cog 2.2 then installed the 3 files for jupitor v006, deleted gps data, reset phone, stood out side with lbstestmode in position test for about 10 minutes, and thats about it, now i get a quick lock and good accuracy even while moving, do you want me to enable logging so we can view it? maybe mine is different hardware wise. when i did my tracks i had my phone on the dash, but if i was going to use this with nav I would have it there anyways. I hope this helps anyone, having no success.
[Captivate Android Development] jboz:
Thanks for everyones work and suggestions on how to "fix" the gps issues, but I am still confused what people mean when they say their gps is "fixed" now. If I first start an app like GPSTest a similar test in LbsTestMode and get a lock, then go to an app that uses mapping I will get a lock and all is well. BUT, if I just wake up one morning and want to see where the closest coffee place is using Where or Places for example, and I go to those apps directly without first starting up GPSTest, they will just keep hunting for a GPS lock.

My point is that it is not just the Nav and Maps apps that do not work, but any app that relies on GPS data. They will not work unless a GPS specific test is run first so that there is an existing lock. If I have a prior lock then the Nav app will track well if I leave the phone on the dash too. But what happens if there is no prior lock?

Is this what everyone else is finding? Or after a "fix" are you saying that all apps that rely on gps data work as intended providing you with info reasonably quickly when launched?

FYI .. I am running 2.1.1 and switched to the supl.google.com setting with port 7276 and find that it works better than stock, but I still have the problems mentioned above.

Thanks for the clarifcations.
[Captivate Android Development] ceebz:
I have had good results with resets, etc. However, GPS performance seems to degrade over time, regardless of fix.
[Captivate Android Development] schahr01:
A few questions -

Is the captivate supposed to be able to lock without the use of any data connection? Just tried to get a lock with GPS Status and the stock GPS configs on Froyo JI6 - I see that it knows about 8 satellites but it never locks. I remember reading somewhere that the antenna and/or chipset is not strong enough to get a lock unassisted.

Is this what the goal of updating jupiter.xml and other config files is or is it simply to improve being able to lock using aGPS (data connection)?

Is the use of aGPS the same as using a SUPL config?

Thanks in advance...
[Captivate Android Development] ajayendra:
My experience today...got excited and then :(

I am coming from HD2 and Nexus One background and I have used GPS extensively on those phones.

Did this: JF6 One click Odin, root, Cog 2.2

--- poor results on GPS no lock stability at all

replaced default with supl.google.com and 7276

--- okay results but lost locks very often, not reliable at all

installed Jupiter 6, deleted GPS data and reset

--- on a 12 mile drive during lunch, I started with a lock and boy that was something!..Having said the experience with N1 and HD2, the lock was stable, it was awesome!...no circles around the phone, no inertia effect on the ongoing road... 9.5/10

--- Left the spot for back to the office (deleted gps data),started google nav, had lost lock, never got a solid lock, circles for almost the entire route, pathetic results :(

I am guessing that gps degrades with time, but one way it was solid and coming back, aweful!..Only experts can have comments on that.

Just feeding back...
[Captivate Android Development] imb951:
To be clear, I have searched this thread.

How do you install Jupiter V6 on Cog 2.2? I downloaded the zip file, do I simply rename to update.zip and flash via stock recovery?

Or do I have to extract the files and use ADB to copy them over?
[Captivate Android Development] pkley:
Save the files to your phone and extract them. Copy to the /system/etc folder. I personally used Super Manager app to give me root permissions and to copy the files.
[Captivate Android Development] pkley:
Using COG Froyo 2.2 GPS is still flaky when using navigation or tracks.

I also tried the .006 files and not much improvement. About the same with SUPL.google.com 7276.

I get a lock pretty good when using GPS Test or LBSTest Get Position but very erratic behavior when actually using the navigation/track. Tracks definitely has a tendency to want to keep me going in a straight line when I make turns/on-ramp loops.
[Captivate Android Development] ThisWasATriumph:
I wonder why this happens? We need to play with the cache settings or turn it off somehow.
[Captivate Android Development] ajayendra:
Ok...test continue: Before starting to go back home, I had restarted the device. Started with a locked position, and again for 5 miles the lock was solid and very much comparable to N1. Then I turned the nav off just to replicate the earlier day situation. Was driving at about 65mph and started nav after about 2 miles, almost instant lock!!

Turned off nav after couple of miles and waited for about another 5 miles and turned nav back on, instant and accurate lock again while in motion, great nav too...

So... I could not duplicate the problem doing the test at lunch time and while going back home. However, I think rebooting has something to do with it..but hey I am not a programmer or an expert..so I will let the OP and other masters think over it.

Just my 2 cents...
[Captivate Android Development] Haloruler64:
So I switched to the google SUPL, and running Cog 2.2 with no custom GPS fixes. I am in the hills of Daly City, California, where its CONSTANT fog. I was walking the dog, and got 7-10 satellites and a great lock and great accuracy and tracking. I went off the road in a curve and it tracked my exact movement. I've been running the same instlal of Cog 2.2 for 3 days, so its not like it wore off. Also, in the middle of Civic Center if San Francisco in a 6 story building on the fifth floor, I couldnt get a lock

EDIT: The lock was just a few minutes, nothing extensive. But worked very well. First time I even GOT a lock more than one day in a row, my GPS used to be COMPLETELY broken before
[Captivate Android Development] MrByte:
Well, not sure what I am doing wrong. Downloaded the Jupiter-v006.zip and pushed all 3 files into their respective folder, rebooted the phone, and when going into the Lbstestmode app, my previpus settings are still there. I checked if the files had the modifications made, and they do..... what am I missing?
[Captivate Android Development] ajayendra:
They do not change...
[Captivate Android Development] MrByte:
What do you mean by "they do not change" ?

I would assume that if the contents of these files change, when you open the lbstesmode app you would see the changed values...???
[Captivate Android Development] ajayendra:
Maybe they would but I didn't notice any.....I meant I didn't see any change in SUPL/CP settings neither application settings...what changes are you expecting BTW?.
[Captivate Android Development] MrByte:
Well, for starters I would expect to see the change of the server and port, which is different than the one I had set. In other words, I would expect the application to reflect the values stored in the config files....
[Captivate Android Development] ajayendra:
Guess we need some help here from ShortFuse....
[Captivate Android Development] drancid:
try supl mode to Control Plane.

works for me!!!!

cog 2.2 + OCLF + Jupiter v006
[Captivate Android Development] n19htmare:
Here's my analysis of the Captivate GPS..... It's a Piece of **** and completely worthless in its current state.
[Captivate Android Development] slyguy2000:
+1
[Captivate Android Development] nickbarbs:
+2.

Completely true. Damn
[Captivate Android Development] imb951:
FWIW, I still haven't loaded the Jupiter v6 on to my COG 2.2 install.

All I did yesterday to my Lbstestmode settings was change the server to supl.google.com and port 7276. I have had 90% reliable navigation on three different instances driving around town, only losing lock when I was in heavy tree cover, and in a parking garage. I was pretty damn impressed, given no other changes to my gps settings.
[Captivate Android Development] ajayendra:
Driving to office I did again a series of tests, looks like rebooting alone doesn't results in magic.

Deleted gps data, rebooted and saw good locks...I would like to confirm it by doing another series of tests.

Members, could you please do a "delete gps data and reboot" and see how nav works?...I will when I drive back home...

well only if you have the same settings as mine

(JF6->Cog2.2->supl.google.com/7276->Jupiter 6)

Thanks
[Captivate Android Development] ronpinoy253:
I would like to report that this configuration also works very very damn good for me. Like me GPS works as good as my standalone GPS with these settings and rarely lags.

My Settings:

Cog 2.2

OCLF

Jupiter v006

changed settings in LBSTESTMODE to "Control Plane" and supl to "supl.google.com" "7276" Secure Socket "Off"

Turns and freeway speeds the gps tracked me excellently and never saw a large radius bubble, gps lost me only for ~2 seconds when I quickly accelerated around a corner (safely of course) to get up to 40 mph after being at 5 mph. Then was spot on the rest of the way. Hopefully this works consistently.
[Captivate Android Development] skinien:
Hi all. I tried to delete GPS data and my phone shuts off. Any reason why that would happen?

I moved the v6 files over and I can see satellites faster buy my location is really jumpy.

EDIT: Only happened once. I pressed delete GPS data, it froze for a second, vibrated twice and shut off. Not happening any more.
[Captivate Android Development] ajayendra:
Never happened to me...
[Captivate Android Development] MrByte:
What do you have in Application Settings/Operation Mode ?

Also, as I had posted earlier. Copying the Jupiter v006 files to the appropriate locations does not reflect when I open lbstestmode app. Is there anything else to do besides replacing the files and rebooting the device?
[Captivate Android Development] brandonb81:
GPS is still atrocious for me on 2.2, so I am going to try out the Jupiter 006 file. I will copy over the files, reboot the phone and do the delete GPS data option and try the navigation on the way home. I'll report back, but I suspect it'll need to be left intact for a few days to really get any idea if anything's been resolved or not.
[Captivate Android Development] pkley:
The Jupiter files don't do anything to the lbstestmode app settings. In fact it's widely believed that many of the settings in lbstestmode only apply to that specific app and not much outside of it. Maybe the SUPL settings, but beyond that I don't think it does anything.

Personally I think we have multiple issues, for me the GPS Test Mode app and the Get Position Fix app seem to work pretty well but that doesn't seem to translate to any of the Google Maps/Nav/Tracks apps. Very hit or miss.
[Captivate Android Development] ronpinoy253:
Operation mode is in stand-alone for me...the only major change I do as I posted is use "Control Plane" mode instead of "SUPL"...doing this worked for my navigation but I will test more later...but so far the best my GPS has ever been (even better than Cog 2.1.4 with the Cog 2.1.5 update and Jupiter v005). I am going to test with the wireless networks off and see how it performs on my way home from work.
[Captivate Android Development] MrByte:
Thanks.... Let me try again then putting the files on the phone, making the SUPL changes, rebooting, and then test it on my way home.....
[Captivate Android Development] drancid:
Mine is Ms Base mode.

But imma try Standalone mode when i'm going back home.
[Captivate Android Development] tazman171:
I'm in standalon mode too on cog's Froyo beta 2.2 and no jupiters added. Using the spirent server still as this has worked awesome since flashing cog 3 days ago. It's at least 95% complete for me, very usable now. Even when it was raining like hell yesterday it still had 7 for 7 locked and stayed on those same sats 90% of the time which is 200% improvement over JF6 constantly dumping locked sats.

It does sound like each users experiences are different, but when aren't they. :cool:
[Captivate Android Development] MrByte:
I know... alt this only adds to the confusion.... as someone posted earlier... the overall GPS performance on this phone sucks, for most of us....
[Captivate Android Development] drancid:
Yup!!

For an example, my gf has captivate also we bought at the same time.

But her gps works just fine.. i just chaned supl server to google.

No jupiter files.. and her phone's stock rom with voodoo fix 1.9.

In the lbstestmode, het gps signal's way better than mine.

The strongest one is over 44!! mine's only 36.

Her phone locks her position in 15 secs all the times!! wth...

So she has no complaint so far..

She always tells me to stop messing up the phone.. (i'm trying to fix it!!!!)

In this case.. i think my gps chip is kinda piece of junk....
[Captivate Android Development] n19htmare:
I've tried so many things and this thing is so unpredictable that you just can't rely on it to get you out of a tough spot.

On my iphone, when I was using it, I could be in buildings, in stores, and it locked and put a dot right on the dot (pun intended) in a matter of SECONDS and i mean like 5 seconds or less. All the time and Every time.

I love everything about android and this phone minus the GPS. If you really want to compete, in my opinion, you can't have this kind of a problem.

it needs to be fixed but I'm affraid it may not be a software issue AT ALL. The antnna system of the phone is of poor quality it seems because even my 3GS had BETTER reception, BETTER gps, and BETTER wifi reception.

I really don't understand why this phone is lacking in all three!
[Captivate Android Development] Brynn85:
I concur :-/

And I really *hate* to have to use a comparison against the iPhone because that's not how a phone should be rated, but in truth, I had such high hopes for at least a more reliable signal and less dropped calls... I didn't know there actually was a phone that could drop calls more than my 3GS, that's one of the biggest things I hated about my iPhone.

Now I get a weaker signal and have more frequently dropped calls, and the GPS issue sucks... Especially yesterday when a main road I use to get home from school was closed down and I had no clue what other route I could take... my Captivate was basically useless cause it wouldn't even lock where I was located (which is a big deal when you live in a small town with two lane roads and mountains and fields around you; not a lot of landmarks to help you figure it out.)

I like the phone and Android also and am reallyyy hoping software can fix the problem and that it's not all based on the hardware itself, cause that will suck majorly.
[Captivate Android Development] 1randomtask:
So, can I install v006 on Cog 2.1.6 and its 2 kernel variants?

Also is it possible to do this from the handset itself (my desktop pc has the wrong Samsung USB drivers, thus I can't access the handset from that)?

I have full access from Astro etc?
[Captivate Android Development] MrByte:
You should be able to, using a Terminal App. With Astro you don't get (I think) su access to touch the system files.

Always backup the original files before messing with them...
[Captivate Android Development] creepyncrawly:
I believe CLShrotFuse said v006 is for cog 2.2 Froyo UCJI6, and for UCJH7, Cog 2.1.6 and smaller you should use v005.
[Captivate Android Development] 1randomtask:
exactly what i'm wanting to confirm.

[Captivate Android Development] ewingr:
I've been watching and I want to attempt some of this. But I as so confused now, having read so many "I am using...", etc.

I just flashed Cog 2.1.6.

I noticed that the previous poster ased about applying Jupitor 6. Is that the recommended file to use now, for the most part?

It does seem to me I've seen more folks say they are quite successful with Cog 2.1.5 and Jupitor 6.

Maybe I should start by doing the GPS Reset.

Whewh....

[EDIT]

I've found posts that seem to indicate I should use 5.

Going to copy both files to the system/etc folder. I also did the GSM Reload. I'll post how it goes.

[Captivate Android Development] 1randomtask:
In your opinion, does 2.2 + your Jupiter.xml fix bring the Captivate up to scratch GPS wise?
[Captivate Android Development] pkley:
While not perfect, it's the best I've seen I think. Had a walk across the street to the store and back and it had some issues, but the 30 minute windy drive home was pretty impressive. Of course at the end, driving in my wooded subdivision I was apparently driving between the lots, but other than that it was pretty accurate. Just reviewed it on my PC and it's actually REALLY accurate, no apparent inertia. I'd say the worst it was off was by 30M, but only when I was going relatively slow. All the turns up the hill were tracked within 10M I'd say.

COG 2.2Beta1 & J006.

Still doesn't like to lock in Google's software unless I use GPS Test or lbstest get position. Depends on signal strength.
[Captivate Android Development] Dani897:
I did a couple actual tests with my tracks, curiously using sensor assist makes it worse. it over estimate turns and give apparent inertia. or that'd how it seemed.

I'll do a couple more runs giving it an a/b a/b b/a comparison, or maybe a/b a/b b/a b/a a/b for good measure soon.

my drive with sensor assist off was remarkably accurate. and I gave it every reason to be in accurate, phone was on the passenger seat so it had a metal roof over it. the weather was horrible, rain, clouds, thunder, but it didn't show me driving through the lake our any thing goofy like that. actually the only place it showed me other than where I actually was was in my driveway. and then it was within 30 feet.

it says sensor assist increases accuracy and saves battery, well I'm sure it saves battery probably by reducing the frequency of updates by the actual gps, but the accuracy was about as bad as I've seen it on this phone. it seems to be out of sync or have the orientation wrong or something often showing the orientation of the arrow different from that of the direction of the car. it showed my position off by 300 ft or more at times.
[Captivate Android Development] Zukoso:
I'm using Cog 2.2 with jupiter v006...decided to take a 5 minutes walk outside the office, and this is what my tracks recorded...

http://yfrog.com/n4sj7p

pretty fine cosidering some maps here in Chile got screwed after the earthquake...
[Captivate Android Development] pkley:
I wonder if the sensor assist is assuming that you're holding the unit flat? I noticed that my compass in tracks actually is working currently as long as I hold it flat, but if it's near vertical it's skewed to one side.
[Captivate Android Development] tytdfn:
Didn't cl say that v006 messes with the compass so... im not sure what other sensors it would use besides the compass.
[Captivate Android Development] mikewong27:
v006 works great on my captivate running froyo. This morning I could not get any gps lock for 20 minutes (after upgrading to froyo). I put the files from v006 into my captivate, and now my gps is working!!! Thanks a lot :)
[Captivate Android Development] CLShortFuse:
I want people with gps issues to get Micro Second from the app store, disable auto-time fix from settings and resync their clocks with the app. I had a 5.2 second difference. Maybe that caused the sliding issue. This could also explain why rebooting works. When you reboot your phone, it resyncs the time clock.
[Captivate Android Development] max_warheads:
I am seeing approximately .75- 1.5 second difference.

Edit: ouch. after disabling network sync.. it jumped from .9606 to 2.11 after about 30 seconds!
[Captivate Android Development] CLShortFuse:
I set Micro Second to alert me if my desync is greater than 1 second.

Edit: Comparing with http://nist.time.gov/timezone.cgi?Eastern/d/-5/java I don't think Micro Second is working correctly. I'm going to change the NTP

I'm using http://tf.nist.gov/tf-cgi/servers.cgi

It does seem like it desyncs rather quickly. That should be fixed in the kernel.
[Captivate Android Development] max_warheads:
Ok, well for informational purposes:

JH7 OTA, Voodoo kernel v1.9, jumps upwards of 2.5 seconds.

I will switch as well and have a look. Server: time-a.nist.gov

Edit: still jumping to 2.184+ after ~1 min
[Captivate Android Development] drancid:
I think you can also check on lbstestmode with supl setting control plane.

Mine is around 0.9 sec diff and never goes up over 1.6 secs.

And lbstestmode updates the value every second.

Cog 2.2 beta 4 + oclf + jupiter v006

Edit. Never mind.. that is elapsed time..

I just have 0.163063 sec diff on microsecond app.

Tested for 3 mins.
[Captivate Android Development] ewingr:
I found somdthing interesting with MyTracks/Google Map

I did my first test run with MyTracks, and after my implmentation with:

Cognition 2.1.6

GSM Reset

Jupiter5

And the interesting part is this: when zooming in to s ee how close to the road it gets me, it looks pretty far off if looking at it in MAP mode, but when in SATELLITE mode, it looks darn near perfect.

Haven't seen anyone mention this, but so many are using MyTracks to make judgments, this seems an important point.
