It seems nobody gets a quick fix. Times range from 10 to 60 minutes if
any fix at all. There is a similar thread running on the developer list
but no answers from Openmoko. Normal for a cold start would be
45secs-2min and with agps ~15secs. This is industry standard and stated
on the specs page of u-blox. The GTA01 (Neo 1973) gets a fix in one
minute after a cold start.
All modern chips (and the u-blox is a modern chip) can get a fix without
downloading the full almanac (which takes 12.5 minutes). The ephemeris
is sufficient and comes in 30secs.
I think this is an important issue and hope that Sean or Wolfgang can
give answers. I CC'd Steve too, because this equally effects the VAR
If they don't answer it is probably the best to send your FR back before
the warrenty expires and buy a new FR once this issue is resolved.
