A Study for Avoidance Alarm Algorithm with ADS-B Message

Abstract

[Abstract]In the end of 1990's, future free flight technology had been developed and tested in America and government established the plan for free flight until 2017. Aircraft separation assurance must be secured essentially to avoid collision between aircrafts before Free Flight comes true. Now, Civil aircraft has rules about avoidance activity with traffic collision avoidance system (TCAS) but it can`t apply to light aircraft. So there is a need about alternative method to apply light-aircraft because it has space and price problem to use TCAS. In this paper, TCAS algorithm has been modified and verified by simulating with LABVIEW program under ADS-B condition to get miniaturization and weight lighting cheaply. By simulating, collision alert algorithm is analyzed and verified with collision situation proposed by ICAO, and 100% checked for performing the alert announciation on all cases by TCAS standards.

Analysis of surveillance position error for airfield detection

“…The precision can be further enhanced using additional correction measures. However, the ADS-B technology is completely dependent on the aircraft for the position information, and ATC facilities cannot directly manage the stage of position information generation, which results in an inconsistent reliability of the obtained information (Schuster and Ochieng, 2011;Ju et al, 2014).…”
