Another thing is that I get placed in googlemaps to Sao Lazaro (Macau) which is not really Berlin. It only happens when I am connected to the NanoBTS and no other position can be retrieved. It happens with a Nokia phone (N78) as well as with one from Motorola (Milestone). This is not a problem since it goes to the right position as soon as it has found enough satellites but indoors and without A-GPS working it places me to Sao Lazaro. Just curious what that could mean.
I would simply guess that it is some hard-coded default in case the MCC/MNC/LAC is not known to whichever entity on the network that decides your location based on that information.
What kind of MCC / MNC are you using? Have you tried changing them to one that exists in reality and checked where you get placed on the map now?
I used the default one in the config file but now I changed it first to 202-1 (Cosmote - Greece) and than to 268-3 (Optimus - Portugal). They both placed me in the ocean between Havanna and the Everglades. So it seems that something is hard-coded in the SUPL server but why is this value not always the same and why is that point so far away from Portugal/Greece? Maybe I should try another SUPL server and see if they place me at the same place for the same MCC/MNC combination. Thanks, Andreas
