Data processing methods for autonomous on-board surveillance and collision avoidance

In this contribution, an ADS-B based airborne co-operative surveillance function, being the basis for an autonomous collision prediction function, is proposed. The main capabilities of the integrated data processing architecture provided will be detailed. This includes track formation, message-to-track association, coordinate transformation, position/velocity filtering, and conflict detection based on the concept of miss distance. Results illustrating the effectiveness of the system, based on rigorous modelling of navigation errors and communication channels, are presented
