    FR24feed uploader - Additional Info

    Feel free to post/discuss on this thread here

    FR24feed Errors
    Linux/Pi feeder Specific Information
    Beast/Transponder Mouse
    ADSBScope / VRS / RTl1090
    SBS Example
    Web Config Examples

    How does it work?
    The developers have made a package uploader that consists of 3 core parts:
    Direct hardware access files
    RTL SDR software - Dump1090
    FR24 log, filter, bundle and upload data application

    On startup the software will:
    - Scan the configuration file for your setup (answered during install)
    - Evaluate if chosen source type is native (dump1090 not used) or not (Dump1090 needed)
    - Load appropriate connection to receiver
    - Pass data to be uploaded
    - Output any connection or various errors during startup

    Collecting received data:
    Your data and Hardware will be connected to in 2 ways depending on receiver type:

    - Feeder will be loaded and 'liven' USB or Com port specified direct
    - Dump1090 will be launched and connect to DBVT for FR24feeder to collect (1 step)
    - FR24feeder will connect to dump1090 output (2 step required)

    - FR24feeder will ignore Dump1090 and connect direct to hardware (if readable format output)

    Data is gathered, bundled and sent around every 5 seconds.
    Your status may falsely show 'online' if the connector portion is running, but have issues with data collection
    Status may show 'offline' if no data is collected or sent to server (bad reception or no traffic, Dump1090 errors)

    There are many reasons incorrect configuration and 3rd party software can cause issues if not configured correctly, So please read further!

    Web Page Configuration - (Fixing startup errors):
    This is the easiest way to check/re-configure the software when FR24feed core successfully running
    (to fix incorrect option errors entered/found on first run)

    --> http://localhost:8754 <--
    (or replace localhost with the IP address of Rpi or PC running software)

    !You can also edit the config manually - but variable options will need to be known!

    USB DVBT Feeding:

    Dump1090/FR require a Realtek/RTL 28xx chipset, and E4000 or R820 tuner
    FitPower/FC will likely not not work

    New users advised to start FR24feed standalone without RTL1090 (or Dump1090) present, or any additional commands such as --interactive as this will cause new or inexperienced users un-diagnosable issues.

    Do NOT enable raw/basestation/SBS output on first setup unless you are familiar with data-flow or certain similar output on other software is disabled

    ! These MAY be enabled after for more advanced data use again if running certain hardware and are sure nothing will conflict by doing so !

    - Reconfigure/Configure FR24feed to DVBT (or AVR-TCP/BEAST-TCP mode for already running Dump1090)
    - if not already identified on launch add --net to additional commands to enable web output port (8080,30002)
    - Adjust other software data source settings to open AVR/RAW port (added by --net) on localhost:30002
    - Save and restart feeder

    *Running additional software with FR24feed can be complicated. Not all instances or configuration examples can be given due to this
    Ensure you search the following threads for further info from other helpful users:

    Cross Platform
    Raspberry Pi based

    Pi24 Image
    Pi24 is designed for first time feeders or those not familiar with linux SSH/Console. It automates the process of setting up the feed software and allocating a radar ID
    Image has a pre-installed version of Dump1090 and may allocate an additional radar ID during setup questionnaire even if you had an active ID previously

    RaspberryPi with FR24feed & PiAware or currently running Dump1090:
    If you have previously installed PiAware separate (or Dump1090) - it may be running already. In this instance configure your feeder as AVR-TCP as above NOT USB DVBT or you will face errors similar to error examples below

    AVRTCP config example when running Dump1090/Dump1090-mutability/Piaware/
    *FR24feed Setup Wizard may auto-detect running instance and assist selecting right option

    Other Hardware (not DVBT) Data Relay:

    The options found for RAW/Decoded and SBS data out are valid for other receivers.
    For instance RAW out enabled for a BEAST receiver will open port 30334. While RAW using DVBT config will open 30002
    MPX/SBS out option when used with Kinetic hardware will repeat data on port 20072

    Configure Additional Software:

    Software such as VRS(virtual radar server) and ADSBScope can then be configured to NETWORK data source on those ports
    - You must start with other Server functions of these applications disabled to prevent conflict errors!

    MLAT contacts are server-side triangulated - Source data from Radarcape based receivers + GPS time (Primary) + RPi/DVBT/Dump1090 using NTP time tag (NOT GPS!!) secondary
    RPi MLAT will NOT be enhanced with a USB GPS module
    - due to interface/port transmission speeds adding jitter delays NTP is used for syncronised reference data

    MLAT requires 4+ in-range receivers:
    - Various combinations of Rpi + FR24 receivers contribute (1FR + 3 Pi, 2FR + 2Pi etc)
    - min. 1x FR24 receiver required in combination
    - Overlapping FR24 Receiver GPS-time MLAT prioritised
    - NTP used for commonreference on RPis alongside FR24 data
    - All receivers need to contact the same Mode-S Only aircraft (and 1x ADSB reference aircraft).

    Attributed on the map calculated from FR24 boxes majority:
    T-MLAT (Europe/Africa)
    T-MLAT2 (North and South America)
    T-MLAT5 (Asia/India/Japan)
    T-MLAT3 (Oceania)
