## Assisted GPS

GPS can take a long time (~5 minutes) to get an accurate position the first time it is used. AGPS uploads a few hints to the GPS receiver about satellite positions that allow it to get a faster, more accurate fix - however they are only valid for a short period of time.

You can upload data that covers a longer period of time, but the upload will take longer.

AGPS Validity time 1 day (8kB) 2 days (14kB) 3 days (20kB) 1 week (46kB)

Using fewer GNSS systems may decrease the time to fix. (If unsure, select only GPS)
