get a fix _at all_ if either position or time is outside the claimed

U-blox receiver allows polling AID-EPH, AID-ALM data.
For each type, we can poll 32 messages for 32 satellites.
The precondition is: current fix is valid -- at least 3 SVs has valid EPH(or

These data get invalid 2~4 hours

is only valid for 30min
or so. Saving the ephemeris locally helps if your gps app crash and gets
restarted, but it won't help you the following day. A server could help
though.

Yes frameworkd ogpsd has some info about it:

But where do we get this almanac data? Can we redistribute what
u-box.com sends us?
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

What about if we hack the data format of u-blox AGPS offline file, and
extract data for current location and time? location can be specified by
clicking map, time from local system time. If we could, we would be able to

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.
Kind regards,

would it be possible to get the satelite information that we get from

somewhere that dont require user account?
