Problems solved by technology

[0003] ADS-B uses the broadcast method to share the transmission channel, instead of the roll call inquiry adopted by the traditional Mode S, and the interference caused by this increases
In addition, each ADS-B message is composed of 112-bit data information, and each message contains a large number of information units, and the bits occupied by the information units in each message have no certain rules to follow
Therefore, it is difficult for general analysis methods to quickly and efficiently analyze ADS-B messages

Abstract

The invention discloses a method and system for ADS-B message data analysis. The method for ADS-B message data analysis comprises the following steps: firstly, defining a multilevel, joint and extensible structure; then, analyzing the validity of the ADS-B message; and then, analyzing the type of the ADS-B message; and then, analyzing the content of the ADS-B message. The method for ADS-B message data analysis can analyze the ADS-B message quickly, efficiently and flexibly; in addition, the accuracy, stability and reliability of the ADS-B message data analysis can be improved by performing fault-tolerant processing on the analyzed ADS-B message structure.

Description

technical field [0001] The invention relates to the technical field of aviation control, in particular to an ADS-B message data analysis method and system. Background technique [0002] Traditional secondary radar monitors targets based on inquiry and response methods. Due to high cost, difficulty in installation, and difficulty in comprehensive coverage, it has been unable to meet the rapidly developing air transport industry. Automatic Dependent Surveillance-Broadcast (ADS-B) is a new air traffic monitoring technology based on the global satellite positioning system and using air-ground and air-air data link communications to complete traffic monitoring and information transmission. Improve airspace utilization. 1090MHz ES ADS-B is the only mode recommended by the International Civil Aviation Organization. The system can realize ADS-B message encoding only by slightly modifying the Mode S transponder. Compared with the traditional surveillance technology, the ADS-B syste...
