A-GPS or Multicell location

[Georgiy Lutsenko]

Hi 

I am successfully reading GNSS coordinates and sending them to AWS server. However, I have to stop gnss as soon as the modem goes into RRC Connected mode and resume work on RRC Idle. Everything works, but getting the coordinates takes a very long time.
From the description of A-GPS, I learned that this can be accelerated, and using Multicell will help to find out the approximate coordinates.
But in the examples, the setting for nrf cloud is indicated everywhere. Is it possible to use A-GPS and Multicell without NRF cloud and are there any examples?
I'm using SDK version 1.9.

Best regards,

Georgiy

Hello,

We have a sample for multicell which you can start as a starting point https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/samples/nrf9160/multicell_location/README.html. 

GPS and multicell measurement are two different things. If you would like to use the multicell information to get an approximate location in the application then the multicell_location sample is fine. 

You also can use the AT command https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/ncellmeas.html

Since AGPS is an assisted service, so Satellite data is downloaded from an external source. nRF cloud provides this information, however uses an external source as well. Google SUPL client library could be an alternative  https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/libraries/others/supl_os_client.html#supl-client-and-supl-client-os-integration

Thanks.
