[maemo-developers] N900 GPS Problems

[From: Aniello Del Sorbo]

Are you guys using the N900 with a SIM and a data plan on it?

The GPS on most phones are Assisted-GPS chips.
That means that IF there is a network connection, they will use SUPL
servers to reduce the time of fix to a bare few seconds.
But if there is no data connection, then they will behave as regular
GPSes and the time for the fix can go up to 20-30 mins.

Do not compare these GPS chips with the ones in specialized navigators
as they tend to be much more optimized and they usually store some
data locally or have a better antenna, not really sure, but they are
designed to get a fix asap [that's what you also pay for!].

I do have a data plan and I get a fix, every time, in seconds.
