Satisfying airport operational requirements using GNSS

摘要

The successful implementation of a seamless, DGPS-based airportnnavigation, control and management system is dependent on the successfulnintegration of avionics and Air Traffic Management (ATM) technologies.nDifferential GPS (DGPS) position, velocity and time (PVT) data cannprovide pilots with world-wide, all-weather navigation capabilities,nincluding forms of precision approach, taxi and departure guidance.nAutomatic Dependent Surveillance Broadcast (ADS-B) can give allnparticipants a dynamic view of the airspace (or airport surface) andnprovide the ATM system with the inputs it needs to manage air and groundntraffic safely and efficiently. Using common, safety-enhancingnalgorithms, GPS and datalink can provide improved benefits to the vastnmajority of aviation system users and operators. To maximize thenstrength and versatility of an integrated GPS-based airport system,ninternational standards are required for navigation, geodesy, avionics,nand datalink(s). The first step in developing these standards is thendefinition of high-level operational requirements for seamless airportnoperations. This paper describes a set of key, high-level operationalnrequirements for a DGPS-based airport navigation, control and managementnsystem. The requirements are translated into a specific technologynimplementation utilizing GPS and datalink. The concepts presented herenare based on the real time test activities conducted by DSDC at thenManchester, NH airport
