Hi,
I was wondering if you could give me information on the validity period of the GPS assistance data?
In other words, how often do you need to download the data? I can't seem to find any documentation on this?
Kind regards,
Thomas

Hi!
The use of A-GPS doesn't change the amount of time the data is valid, just the time it takes to acquire it. The ephemeris is valid for four hours and the almanac is valid for up to two weeks.
However, the modem should request this data when it needs it, so this process should be automatic and independent of your application.
Best regards,
Heidi
