In this paper, we consider an allocation problem of orbits in outer space and within the electromagnetic spectrum. Telecommunications satellites use two kinds of resources: space in orbit and frequency band. A conceptual model of outer space is developed to examine the optimal allocation problem. The optimal location of a system of satellites in outer space is derived. It is shown that the shadow price of outer space is a decreasing function of altitude.
