A study of communication systems that use radio signals reflected from artificial earth satellites. Four main problem areas are examined: parameters affecting circuit capacity, the effect of orbital configuration on satellite visibility and continuity of service, systems trade-offs and costs, and comparisons with active repeater satellites. The conclusions are generally encouraging to the economic potential of passive reflector satellites, provided that a significant increase in reflecting cross section per unit weight over that of Echo I can be achieved and that higher power levels than are now generally available in the frequency range of interest are employed. Tolerable levels of service discontinuities appear to be possible, even when the number of satellites is not excessively large.
