Enhancement of Passive Surveillance System for Airport Surface Movement

Abstract

The multilateration is an aircraft surveillance system for airport surface movement utilizing hyperbolic positioning. The system performances are sometimes degraded by multipath signals in an airport apron area. ENRI has proposed an enhanced multilateration system named as OCTPASS (Optically Connected Passive Surveillance System), that has an interference immunity in multipath environment. This paper describes evaluation results for OCTPASS prototype equipments.
