The invention discloses a software-defined aeronautical data chain ADS-B message receiving and transmitting method based on a software radio platform. The platform comprises a GNSS positioning module, a barometric altitude module, an aircraft flight control data module, a sent data processing module Raspberry Pi, a software radio sending module HackRF ONE, a sending antenna, a receiving antenna, a software radio receiving module HackRF ONE and a received data processing module Raspberry Pi. The method comprises the following steps: selecting a software-defined aviation data link to monitor the flight state of an aircraft based on the platform according to the electromagnetic spectrum situation of a monitored airspace, and simultaneously performing data complementation and distributed base station data complementation to realize uniform and continuous ADS-B message transceiving and monitoring of all aircrafts in the airspace. The flight safety of the unmanned aerial vehicle in the near-earth low-altitude airspace is ensured, and the unmanned aerial vehicle air traffic control mechanism can conveniently monitor the flight process of the unmanned aerial vehicle in real time.
