L76 backup mode

When the L76 wake-up from backup mode he perform a warm startup?
How many constellation can i use simultaneous?
When easy is on i can set fix rate to less than 1Hz?

Hi Cleberhaack,
The ephemeris data is vaild for 2 hours. If L76 entered backup mode and woke up within 2 hours, it performs a hot startup. When back up time exceeds 2 hours, the ephemeris data is invalid, so it performs a warm startup. In this case, you need to inject the latest ephemeris data if you want to improve TTFF.

L76 can use 23~28 satellites simultaneously.

Yes, you can set fix rate less than 1Hz.

Best regards.

Hi Raphael,
I can use glonas, galileo and GPS in the same time?

Hi cleberhaack,

Yes, GPS, GLONASS and Galileo can be enabled in the same time.

Set by this command: $PMTK353,1,1,1,0,0*2A

Best regards.
