Frustrated with D2G GPS

I have the same problem

Sent from my DROID2 GLOBAL using DroidForums

 

I find leaving GPS on helps alot with this issue. Also uninstalling/reinstalling google maps seemed to help.

 

OEM firmware, rooted. Works gr8 with NDRIVE 10.

 

Your device may or may not be defective depending on your usage. Just giving some background tech info, GPS satelites are moving very fast. Those are not stationary by any mean. So, receiving signal from those satelites and calculation relative distances from satelites doesn't mean your phone can determine current location.

GPS satelites also send out direction of movement so, GPS device can use it to predict next location of satelites and uses it accordingly. Problem is the signal bandwidth from satelites are very very very small so it takes very long time to receive such information from all satelites. This is the case for cold boot. It takes several minutes to receive all. So, if you turn on your phone from completely strange place, your phone needs to receive all such information for a few min.

If your GPS was off for a few sec, those informations are still valid and your GPS can lock immediately.

that's the story for standalone GPS. For the case of Android phone, it can query google server with satelite ID to get equivalent information to predict next movement. Google server responds immediately. So, most of the time, we can enjoy very short lock time. However, if you travel oversea and doesn't have data connection, it will need cold boot, which takes several min.
