Abstract

The invention discloses a 1090MHz ADS-B (Automatic Dependent Surveillance-Broadcast) downlink data chain analysis and verification system based on a CPCI (Compact Peripheral Component Interconnect) structure. The system includes an antenna feed unit, an ADS-B receiver, and a data analysis and verification unit. The antenna feed unit is connected with the ADS-B receiver. The ADS-B receiver is connected with the data analysis and verification unit. The antenna feed unit is used for receiving an ADS-B radio signal. The ADS-B receiver is used for decoding the ADS-B radio signal and sending the ADS-B radio signal to the data analysis and verification unit. The ADS-B receiver adopts a CPCI structure. The system can monitor richer ADS-B information by making use of 1090MHz ADS-B downlink data. Moreover, troubleshooting is facilitated, the safe operation level of the ADS-B ground station equipment and the air traffic control system can be improved, and reference is provided for airline companies in ADS-B airborne equipment function verification. Based on the CPCI structure, the system has higher computing power, and is easy to expand.

Description

technical field [0001] The invention relates to the field of air traffic control, in particular to a 1090MHz ADS-B downlink data link analysis and verification system based on CPCI architecture. Background technique [0002] The International Civil Aviation Organization has identified ADS-B technology as the main development direction of new global navigation technology. my country has also formulated an implementation plan for ADS-B, striving to build an integrated ADS-B operation system, and actively promote the construction and operation of ADS-B. By 2020, the full operation of ADS-B OUT in the whole airspace will be realized. With the comprehensive application of ADS-B technology, the monitoring and analysis of ADS-B data becomes particularly important. [0003] At present, many domestic manufacturers have developed ADS-B ground station products, which can process the received 1090MHz ADS-B downlink data. The current ADS-B monitoring and analysis is mainly to analyze th...
