Updating GNSS almanac

The nRF9160 Global Positioning System (GPS) receiver uses an almanac file to optimize satellite search and achieve location fix in a shorter period of time. The almanac file is preprogrammed, but it is recommended to be updated to the latest available version to ensure an optimal time for the first fix when GPS is activated in the end-product.

The %XFILEWRITE AT command can be used to update the almanac file. For more information on the %XFILEWRITE AT command, see Write content to file %XFILEWRITE in nRF91 AT Commands Reference Guide.
