Abstract : This paper is primarily concerned with methods of choosing optimum locations for tracking stations which provide maximum support for satellites with near equatorial orbits. The method chosen makes use of the considerations that (a) the orbits ground traces are concentrated in the vicinity of the latitude equal to the maximum inclination of the orbit and (b) most of the direct launchings possible from Cape Kennedy will have a very limited range of orbit inclinations; i.e., from 28 1/2 degrees to 34 1/2 degrees. The relative merits of the sites being considered using the above method are then tested using the following criteria: (a) that maximum number of tracking passes per day be supported, (b) that a minimum number of gaps exist in network coverage, (c) that stations provide early orbit support, and (d) that maximum support be given for recovery phases of satellite missions. Using the above method it is possible to select stations locations for a completely new network or to select a station or stations to provide greater support using existing networks. (Author)
