The open glider network project wiki contains information on how to set up their Linux based FLARM decoder that relies on the RTL-SDR for various embedded devices. The project recommends use of a high gain collinear antenna for receiving the weak FLARM signals. FLARM is a low cost and low power consumption ADS-B alternative which is often used by small aircraft such as gliders and helicopters for collision avoidance. With the right antenna, receiver and decoder any aircraft transmitting a FLARM signal could potentially be tracked on a map.įLARM signals are transmitted at 868 MHz and are effectively weaker by 100-1000 times compared to standard ADS-B signals. Over on our Facebook page, a user has let us know about the Open Glider Network project which makes use of the RTL-SDR dongle to decode FLARM. The post Hak5: Using a Solar Powered Embedded Device with an RTL-SDR to Track Aircraft Remotely appeared first on. Then back in the comfort of their offices they were able to remotely connect to the WiFi Pineapple and start a dump1090 webserver and connect to it using Virtual Radar Server.
They took their setup to the top of a hill near to their office and pointed the transmitting WiFi antenna towards their offices. They also used a high gain directional WiFi antenna on both the transmitting and receiving ends. With this setup the WiFi Pineapple is capable of running indefinitely transmitting ADS-B data using just the solar panel and battery. They used a WiFi Pineapple which is a mini Linux based embedded computer as a remote PC and sealed it in a weather tight briefcase with a lead acid battery and solar panel. Over on YouTube Hak5, a popular electronics enthusiast channel has uploaded a video showing their project which involves creating a remote solar powered ADS-B receiver with the RTL-SDR.
