Communications and tracking
Abstract
Many phases of communications theory and practice could not be touched upon in this presentation. It is hoped that these objectives have been obtained: to show how, in a general way, it is possible to get back enough information to Justify a space vehicle; to show how the path of this vehicle may be followed from the ground, and to state some of the obstacles to communications over very long distances.
