Surveillance aspects of the Advanced Air Traffic Management System

Published in:
MIT Lincoln Laboratory Report ATC-10

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 short-term outages.

Final Report: Transponder Test Program

Published in:
MIT Lincoln Laboratory Report ATC-9

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 the aircraft under test was used to couple signals to and from the transponder. The results of measuremetns on 504 transponders installed in general aviation aircraft, 17 transponders installed in military aircraft, and 28 transponders installed in air carrier aircraft are reported. Of these, 31 general aviation, 2 military, and one air carrier transponders were inoperative. The results of measurements of reply frequency, squitter, delay, Mode C operation, dead time, P2/P1 ratio required for suppression, suppression time, framing pulse spacing, power output and sensitivity are included.

Interrogation scheduling for the discrete address beacon system

Author:
Published in:
MIT Lincoln Laboratory Report ATC-8

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

Published in:
MIT Lincoln Laboratory Report ATC-7

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 light many of the features of these systems. These are detailed along with the research and development required to select the most attractive surveillance system.

Technical development plan for a discrete address beacon system, vol. I [draft]

Author:
Published in:
MIT Lincoln Laboratory Report ATC-4-I

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 in close colaboration with FAA personnel in the Office of System Engineering Management and the Systems Research and Development Service. The DABS Technical Development Plan identifies the critical issues and technical options, presents a program for their resolution, followed by the development and test of a feasibility model of the system, and suggests a management structure to coordinate and carry out the many tasks involved in the implementation of the plan.
