Surveillance aspects of the Advanced Air Traffic Management System
Summary
Summary
Three topics with impact on the performance of Air-to Satellite-to-Ground Systems for Air Traffic Control Surveillance are addressed in detail: 1) vulnerability to intentional jamming; 2) performance degradation due to the multiple access noise which results from uncoordinated aircraft transmissions, and 3) tracking techniques for improved surveillance accuracy and reduced...
Final Report: Transponder Test Program
Summary
Summary
Performance parameters of transponders installed in aircraft were measured to determine their degree of compliance with current specifications. A mobile van was outfitted with electronic test equipment which simulated the transmitter and receiver sections of a ground interrogator and which allowed measurement of transponder parameters. A horn antenna located near...
Interrogation scheduling for the discrete address beacon system
Summary
Summary
This report is an attempt to define the interrogation scheduling problem which arised in the implementation of the discrete address beacon idea. The interfaces of this problem with other parts of the beacon system design are discussed, and several specific algorithms for scheduling are analyzed for arrays and rotating antennas.
Concept formulation studies of the surveillance apects of the fourth generation air traffic control system
Summary
Summary
This report presents a first order feasibility study of four particular candidate surveillance systems for the fourth generation air traffic control system. No attempts has been made to compare these systems, rather we have chosen to examine in detail the most crucial aspects of each. This analysis has brought to...
Technical development plan for a discrete address beacon system, vol. II [draft]
Summary
Summary
The Technical Development Plan for a Discrete Address Beacon System is published in two volumes. Volume I is the basic plan, while this volume (Volume II) contains a more detailed description of the 46 tasks recommended for accomplishment during Phase 1 of the development cycle. It also includes cost estimates...
Technical development plan for a discrete address beacon system, vol. I [draft]
Summary
Summary
The requirement for a Discrete Address Beacon System (DABS) was highlighted by the Department of Transportation Air Traffic Control Advisory Committee to provide improved surveillance and ground-air communications in support of air traffic control automation. This document presents a technical development plan for such a system; this plan was developed...
