With flight delays at record levels, monitoring plane movement may become a more widespread hobby. AirNav Systems LLC decodes the Automatic Dependent Surveillance Broadcast radar signals from planes, letting consumers see the same information used by air traffic controllers. The AirNav RadarBox Advanced Real Time ADS-B Radar Receiver 2 updates flight number, aircraft type, altitude, heading and speed once per second. A Microchip Technology Inc. dsPIC33FJ64GP306 is the core of the baseband demodulator circuit, using both a controller and DSP to process incoming data. The system also includes maps with more than 1 million locations, as well as detailed airport information such as runways.
