Considerations for a Small Economical Earth Terminal.
Abstract
A small economical earth terminal which could be used in the Defense Satellite Communications System (DSCS) in the early 1980's is described. This terminal would be small, relatively inexpensive ($250,000), would stress fixed-plant location and unattended operation, and would be designed to support low-data-rate users. A network of such terminals, controlled by a larger network control terminal, is postulated. Communications links between terminals in this network would be established on a demand-assigned, single-channel-per-carrier basis. Basic technical parameters of the terminal are derived based on system considerations. A G/T of 22 dB and an EIRP of 72 dBW are proposed. Support and acquisition requirements are also considered as a means of reducing costs. It is emphasized that judicious application of support and acquisition requirements is essential to achieve the desired cost constraints. It is concluded that the concept of a small economical earth terminal is feasible for use in the DSCS and could be procured in production quantities of 100 terminals within the cost constraints described.
