This is a minor modification to the gps configuration file based on other people's work last year. It adds some extra paramaters to the gps.conf file to enable a quick AGPS lock before actually locking to the GPS.

It helps quicken navigation and route finding, not to mention battery.

In my tests, I was in a car in morning and after a reboot, opened Google Maps. Got a lock within 1 second with error of 20 meters. Within 3 seconds, I had full lock with error of 7-10 meters.

This version is global so NTP servers being used are the generic ones.

Flash using any recovery !

Do you have a zip to flash back to stock? Or can you tell me the name of the file being modified so I can back it up? Thanks!

Any way for us to modify this for our own specific regions?

    Extract the gps.conf file and edit it for your region before putting it back into the zip

    Regions can be found from pool. ntp.org

    Wouldn't it be more accurate if we change servers to NTP_SERVER=0.us.pool.ntp.org, 1.us.pool.ntp.org, 2.us.pool.ntp.org, 3.us.pool.ntp.org

    for the US folks?

    Honestly, it never made any difference in my testing

    Works great in Norway. GPS locks within a second. It did modified secure port from 7276 to 7275 + all the extras. And I did use location
    NTP_SERVER=0.europe.pool.ntp.org. Thanks.
