-1) Install FlightGear. In Ubuntu You can use install the last stable FG from the [PPA repository](https://launchpad.net/~saiarcot895/+archive/ubuntu/flightgear) by following commands: ```sudo add-apt-repository -y -u ppa:saiarcot895/flightgear``` and ```sudo DEBIAN_FRONTEND=noninteractive apt-get -y --quiet install flightgear```

 * Alternatively use the [TF modified FlightGear](https://github.com/ThunderFly-aerospace/FlightGear/wiki) for advanced features of the models. 
 3) Set write permissions to the `Protocols` folder in the FlightGear installation directory. On Ubuntu run ```sudo chmod a+w /usr/share/games/flightgear/Protocol ```

 2) You can probably use a wild set of FG versions - we tested installation with FG 2019.1.1 and 2020.3.8. But in the past, we achieved basic functionality on Debian 9 running FG 2016.1.1 from the distribution repository.

Check where are FG binaries in your system, by executing the command ``` which fgfs```. Then the Advanced Options section of this readme could help you.

 The PX4 is connected to FlightGear through "[generic protocol](http://wiki.flightgear.org/Generic_protocol)", which is served synchronously to the simulator graphics engine frame rate. So the PX4 gets the sensor data in frequency, depending on graphics resources and the current scene. The source code implements the artificial upsampling of sensor data to ~100Hz to avoid stale sensor detection triggers in PX4. Random noise is added to the sensor data.
