GNSS data storage

Hello !

I am using the GPS on my mangOH Yellow, and I wanted to understand what impacts the Time To First Fix (TTFF).

I read some docs on how does a GNSS device works, and I was wondering where does the board store the GNSS data acquired from the satellites ?

I couldn’t find where the ephemeresis or almanach were stored on my board, but they are supposed to be somewhere in a non-volatile memory because it can get a fix in approximately 30 seconds.
This wouldn’t be possible without storing the satellites data beforehand on the board.

Could someone give me more information about this?

Thank you, have a good day !

I think you will have a better chance of getting an answer to that question if you post on the Sierra Wireless forum in the WP module section.

All right I re-posted it here sorry !
