At this weekend I traveled under storm clouds and GPS worked well. May be because I did the following:
1. With help of GPS Aids I took LTO data
2. Before going by car I stay while GPS was taking signals.
Then I was going for more then 300 km without GPS loosing.
I noticed with Nokia 5800 that taking position in moving car is harder than when you are staying.
