I. INTRODUCTION 1.1 Background The exhaustible and dwindling supplies of conventional energy brought into sharp focus in recent years have directed attention at the national level toward the possible utilization of a virtually inexhaustible source of energy, namely, solar power. One of the current scientific concepts involves a Satellite Power System (SPS) in which satellites in geostationary orbit (GEOSAT-s) would collect light energy from the sun and convert it, first, to electricity and, then, to microwaves for transmission to earth and subsequent reconversion to electricity. The technological feat of setting up such SPS is estimated to involve a very large investment running into billions of dollars. A careful analysis of all the factors and ramifications, including the impact of such project on socio-economic, legal, environmental, international and other considerations and an evaluation of alternative courses of action and their likely outcomes and effects is imperative before any rational decisions can be made. 1.2 Objective and Tasks The objective assigned to this paper is to assess the problems in obtaining international agreements on geostationary orbit availability, microwave frequency allocations and microwave exposure standards.
