With the development of air traffic management technology, 1 090 MHz extended squitter (1090ES) data link which realize air-to- ground and air-to-air communication, has been widely used in the field of civil aviation and general aviation. Traditional radar or ADS-B ground station equipment is large and heavy, with the purpose of developing portable and low cost data acquisition system for 1090ES, proposed a solution based on Android platform and radio module, using 1 090 MHz antenna to receive radio signals, with single chip microcomputer (PIC18F2550) to achieve digital signal conversion, in addition to communicate with Android platform through the USB-OTG interface. A data acquisition APP was developed to realize data decoding, data persistence, and flight surveillance. After the testing and verification, the system can effectively collect the 1090ES aviation data, covering the range of over 150 kilometers, plug and play, and has a bright application prospect.
