PROJECT ECHO - SYSTEM CALCULATIONS

Abstract

The primary objective of Project Echo was the transmission of radio communications between points on the earth by reflection from the balloon satellite. This paper describes system calculations made in preparation for the experiment and their adaptation to the problem of interpreting results. The calculations include path loss computations, expected audio signal to-noise ratios, and received signal strength based on orbital parameters.
