An itemized, selective list of relevant general background and specialized materials may be found in the attached Bibliography. 3. ANALYSIS AND EVALUATION OF RELEVANT FINDINGS Our analysis and evaluation of relevant findings will start with a discussion of the issues involved in obtaining international agreements on geostationary orbit availability for power transmission by satellite and move on to such issues relative to microwave frequency allocations and microwave exposure standards. 3.1 Geostationary Orbit The technological advances of the space age have opened the door toward the increasing utilization of the so-called "geostationary orbit" by satellites for telecommunication, broadcast, meteorological and other services. More recently, the possible utilization of geostationary orbit by satellites for purposes of solar energy transmission to earth has come under serious consideration.3 3.1.1 Physical Nature of Geostationary Orbit The geostationary orbit is a circular orbit at a distance of approximately 22,300 miles (35,800 kilometers) above earth's equator. A satellite placed in this orbit turns about the polar axis of the earth in the same direction and with the same period as those of the earth and its orbit lies in the plane of the equator. Such satellite appears stationary in relation to
