    Adding GPS receiver to the radar

    Hello hobbists and professionals!

    I've got a Raspberry pi3 happily feeding from Rome (Italy).

    Found an old GPS receiver in my technological scrap yard.
    I want to use it to get more precise MLAT calculations.
    All I need to do is to connect it and restart fr24feed?

    Thank you very much,
    Francesco

    No, GPS units are not used by raspberry pi for MLAT. Only NTP references.

    It is hard coded into the app.

    Beaglebone and other specific FR24 units, however are modified to use one.

    Only FR24 provided hardware is able to use the GPS time stamp.

    Not sure what type of GPS you have, but if you can set it up as a local stratum 1 NTP server you can help reduce Flightradar's excessive use of the volunteer pool.ntp.org NTP network by pointing the Pi to your local NTP server by adding a line to /etc/hosts:
    Code:
    <IP of local NTP server> 1.africa.pool.ntp.org 1.asia.pool.ntp.org 1.europe.pool.ntp.org 1.north-america.pool.ntp.org 1.oceania.pool.ntp.org 1.south-america.pool.ntp.org

    Got it!
    mmm... so maybe that could be useful if you feed with a 3G dongle where cumulative data usage has to be minimal!
    Thanks for all the contributions
