16. Abstract
This Program Plan is one of a number of Program Plans which cover FAA's engineering and development activities, Two of these Program Plans cover work devoted to the application of space technology to air traffic control. One plan (AEROSA T Program Plan, FAA-ED-17-2), covers the planning, development, engineering, experimentation, and evaluation of an aeronautical satellite communication capability over the Atlantic Ocean while this plan · covers the development and design data and techniques through analysis and experimentation.

EXECUTIVE SUMMARY
Preliminary studies have indicated that the use of satellite techniques could be a means of satisfying future aeronautical communication requirements for both oceanic and CONUS. These studies also indicate that the requirements for over ocean application is much closer in time than the CONUS application.
Combined efforts with other interested nations have resulted in a proposed initial experimental and evaluation program for the Atlantic Ocean during the 1977 and 1982 time period. This is known as the AEROSAT program. The CONUS program is aimed at the post 1990 era. However, both programs have a need for answers to certain basic scientific questions essential to the design of any aeronautical satellite system. The questions relate primarily to radio propagation phenomena and its effect on the transmitted signal to and from the aircraft via the satellite. The fundamental effects are significant variations in power and phase of the signal, possibly resulting in poor voice communication, high error rates in data communication and unacceptable accuracy in location of aircraft. Once the basic character of the various effects are known, it will be possible to develop ways to counter them. This experimental program is thus aimed at characterizing the aeronautical satellite communication channel and developing ways to offset undersirable effects. Additionally, the program is intended to identify promising operational and technical concepts for the use of aeronautical satellites and to compare them with other ways of filling the needs of air traffic control. particularly in the . CONUS.
The general approach is to conduct essential theoretical studies and analyses of aeronautical satellite system concepts and to verify the findings through experimentation. The experimentation program is designed to make the use of NASA Application Technology Satellite series including the ATS-5 and the A TS-F. These activities will be supplemented as required by laboratory work and simulation.
iv

The projects expected from the p_rogram are the identification and characterization of the basic technical and operational problems in the design of an aeronautical satellite system and to determine the best ways· of overcoming these problems. The output of this program will be used in the design of the AEROSAT system and in future studies of the application of satellite techniques to the future CONUS A TC environment.

The initial phase of this program is expected to be completed during the calendar year 1975 with the completion of the ATS-F program. The experimental and evaluation phase of AEROSAT is expected to begin in the late 1976 or early 1977.

Estimated costs for the program, exclusive of AEROSAT and government manpower are:
