Two-sensor precision aircraft and vehicle positioning for safe segment occupancy control system

The ldquosafe segment occupancy control systemrdquo is the basic component of an airport guidance system where all the moving aircrafts are kept safely separated by an empty taxiway segment: the center lights of such segment shall be ldquoredrdquo until the leading aircraft has cleared also the next segment. This requires a very accurate and reliable detection of each aircraft progression from one segment to the following one. The study is focused on the comparative performance analysis of a two-sensor detection system based on a light-weight SMR and a basic multilateration/ADS-B system.
