[Captivate Android Development] betoNL:
First of all you guys need more practice and less theory.

You cannot even read the thread title right, which is not "how we can control the gps" as you wrote but "SGS, glgps, jupiter.xml, and you (how we can control the GPS behavior better)" . Is about TRYING to improve the sgs's gps performance for THOSE who are having problems, such as not getting/holding satellite locks, too low snr values etc. and with that improving accuracy to the acceptable values (5-10 meters)

And further, there is of course iGo versions for android, but the only ones working on the sgs are the 480x800 versions ( Motonav and iGo my way 8.4.2).

Further, if we are talking about apps such as iGo, off course that concerns domestic gps car navigation software, where 5 to 10 meters accuracy is good enough, and all my other standalone gps devices which are equpped with a sirfstarIII gps chipset get at its best 5 meter accuracy.

Again nobody is asking how to improve accuracy further than 5 meters os asking about waas/gnos systems

In the beginning I was using an external gps bluetooth receiver to run iGo flawlessly with no stability issues and today I dont even use the external device anymore, the internal gps receiver is doing just fine.

And I have the videos to demonstrate it, in action, so no screenshots or pics or bla bla.

And again, all the gps issues/threads around the sgs including this thread are more about how to improve the gps performance in the sense of get it working properly and not about trying to get better accuracy than 5 meters of the advantages of waas or whatever...

Any device (and with that I mean also phones) equipped with a sifstarIII chipset or BETTER (and yes, there are phones equipped with sirfstarIII chipsets), get fast and stable satellite fixes, stable navigation and dont need ANY kind of assist at all such Agps or whatever.

What is your experience based on by the way? Which devices do you use and which programs?

You mentioned you wanted to use a external bluetooth device so you can run google navigation on your sgs right? So stick to the issue and go for it....On android it (bluetooth gps) works with any gps program as you can see on my first video

If you don't mind using an external bluetooth gps device, and IF you are one of those having gps problems with the sgs (unlike me), you will solve the problems this way:

External bluetooth gps device + Bluetooth gps mouse App (not forgeting to allow "mock locations" in settings/development) and pick the program of your choice.

On the moment I am using iGo 8.4.2 480x800 and Aura Sygic

Instead of speculating about things that you didnt really try, you can read about some ACTUAL experiences in many threads on this forum like:

with user-experiences and reviews on many compact external gps bluetooth receivers which are working fine with the sgs.

And again the reports are based on users experience and not about stuff you read on wikipedia or wherever

By the way I just found a newer version of iGo my way that is working on the sgs (480x800) with all european maps including Hungary, but it's in another forum which is not allowed to be mentioned here
