Fig.1 ADS-B receiver
1. The antenna has to receive the 1090 MHz radiation and to
convert it into an electric UHF-signal.
2. The receiver selects, amplifies and demodulates the
received signals, and generates an analog signal.
3. The decoder converts analog into digital and detects ADS-B
transmissions inside digital signal.
4. The ADS-B signals are then forwarded to a PC via Wi-Fi
ETERNET connection.
5. The PC decodes the ADS-B information and generate the
virtual radar display. It may support the exchange of ADSB-data via
the internet.
This handbook is focused on the micro ADSB- W iFi and the PC-
software ADSBScope or PlanePloter.
