Can we inject LBS Latitude and longitude to GPS to reduce the fix time?

Hello,

Here are the answers I got.

Normally LBS position (or some other coarse current position) should be part of the AGPS information, but if AGPS does not provide it, it can be injected separately to GPS over LPC API. I do not know how it is done in the application interface, e.g. what AT command to use (and in what order with respect to the other AGPS information).
This is something we currently don't have support for. For GPS, there is no benefit whatsoever to attempt to inject a position with better resolution than serving cell location.
Sorry, we don't have any answers to this.

Hello,

I don't have the answers and will need to forward it to our R&D team. Can you please provide what modem FW version you are running and what NCS version?

Thanks!

KInd regards,
