AGW Ground Station

The Radar2 app "sees" aircraft with legacy systems (Flarm, OGN Trackers, etc.) but, can aircraft equipped with legacy systems see those using Radar2?

Yes, as long as the area is served by a repeating Ground Station.

AGW (Air GateWay) ground station is a simple and inexpensive solution for setting up a fixed ground station that interconnects nearby aircrafts using legacy radio systems with those using internet apps connected to the OGN provider.

AGW has two operating modes:

AGW consists of an antenna, a programmed board and a power supply (cellular type). The cost of the DIY device is just a few tens of eur/usd. The configuration of the AGW device is very easy, it will be sufficient to provide a name for the gateway and its approximate location.

An ideal position to install an AGW station is near an aerodrome, somewhere where there is a wi-fi internet connection, but it can also be installed in a private house where it can serve an area over a 20 km radius (it depends on the position and quality of the antenna).

*  The use of the AGW in RTX mode, in an area without receiving stations, extends the coverage of the OGN network and makes the relative services (e.g. FlightBook) available also to all aircraft located in the area and equipped with legacy radio anti-collision systems.

The current AGW version is 1.0 and it is suitable for Europe, Africa and all countries which use 868 Mhz ISM band.

SW Info

To load the AirGW firmware onto the radio board it is necessary to download it from this site onto a Windows PC and then load it onto the board after connecting it to the PC with a USB cable. Below are the steps to follow.

This procedure can also be used on MacOS but, after installing nanoff, it must be added in the path settings (export PATH=$PATH:~/.dotnet/tools).

AGW Configuration

After loading the firmware on the radio board you need to connect the antenna and place the board where it can receive the wi-fi signal of your internet router. It may be necessary to enclose the board in a waterproof case and use as short an antenna cable as possible.
Power up the radio board and use a computer or smartphone to connect the wi-fi network  (with name AirGW-AP) initially generated by the board. On the computer or smartphone you are using to configure the gateway, open the web browser and enter the address (these instructions will also be visible on the board display). A page for configuring your gateway will be displayed, where you will have to enter:

Confirm the configuration and your gateway is ready to use.

To call the configuration function later, the board must be rebooted with GPIO 34 pin at +3.3v.
