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...
Concept formulation studies of the control aspects of the fourth generation air traffic control system, final report
Summary
Summary
A concept formulation study of the control aspects of the fourth generation air traffic control system is presented. The results of this study are not strongly influenced by present-day equipment. They are influenced by certain aspects of present airspace utilization and procedures which appear necessary for the design of an...
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...
A laser system for detecting shipping in the approach zone at Logan Airport
Summary
Summary
Runway 4-R at Logan Airport cannot now be used with full effectiveness because of tall ships passing through the runway's approach clearance zone. The key to utilizing the full length of Runway 4-R at Logan Airport for longer periods of time is to establish a channel surveillance system that would...

Concept formulation studies of the control aspects of the fourth generation air traffic control system, interim report
Summary
Summary
To develop plans for a viable ATC system over the next 25 years a whole spectrum of studies can be conducted, each concerned with a different time frame. The spectrum, when laid out over time, is bracketed by two extreme cases. 1. One extreme is analysis of the present ATC...
An airborne traffic situation display system
Summary
Summary
An airborne traffic situation display system which could be used as an adjunct to the evolving National Airspace System/Automatic Radar Control Terminal System (NAS/ARTS) is described. In the proposed system, a contemporary realization of an old concept, the NAS/ARTS data are broadcast. A small digital computer in an aircraft then...
Propagation phenomena affecting satellite communications systems operating in the centimeter and millimeter wavelength bands
Summary
Summary
The theories describing the effects of the troposphere on satellite communication systems operating in the microwave region are reviewed. The results of computations based upon the theories and atmospheric models are presented and compared with available experimental data. From the model computations it is seen that rain causes the major...
Radar meteorological applications of automatic film reading
Summary
Summary
The data recording of storm information as detected by a weather radar has been customarily made on photographic film. Research radars and an occasional U. S. Weather Bureau radar are fitted with scope cameras to record the radar plan position indicator (PPI) display. Over the past 15 years a large...
