I hope that fso-gpsd gets updated soon too - it'd sure be nice to take
advantage of a recently saved ephemeris when restartin

AFAIK, the almanac data that framworkd saves from the GPS can come from
u-blox but can also come directly from the GPS satellites. So we could
try to setup some kind of peer-to-peer distribution of the data

not want to tell them where you are all time. Their server also might

Hi Rikard,
Yes, take a look at www.opencellid.org.
This will give you your rough location and you can use that to get the
agps data for your area.
I have some scripts that will do that for you, so just let me know if
you are intressted.
