Abstract: In utilizing different satellite services two natural resources are used. They are the Geostationary-Satellite Orbit and the radio-frequency spectrum. However, these resources are limited. Since they belong to all mankind, they should be used equitably for all nations. To fulfill this, it is necessary to plan them. In this paper a method of planning the orbit based on the acceptable interference has been described. This method is so conceived that it guarantees to each country the freedom to occupy the orbital position when it so decides, avoiding an "a priori" rigid planning and "freezing" of orbital positions and at the same time permitting the application of new technological solutions for the whole period of validity of the plan.
Key words: Geostationary-satellite, INTEL SAT, WARC ORB, interference analysis.
