Voyager-Neptune Telemetry: The DSN 70 Meter Antenna Upgrade

International Telemetering Conference Proceedings / October 26-29, 1987 / Town and Country Hotel, San Diego, CaliforniaThe Deep Space Network is responsible for the acquisition of in-situ science and engineering measurements and navigation data from spacecraft whose missions are to explore the Solar System. It must respond to new opportunities in the mission set supported so as to maintain or enhance mission science value. The large capital investment in such a Network mandates an evolutionary design approach wherein upgrades can be effected at low cost, and if appropriate, on existing capability. The 64-Meter antenna design, completed in 1963, is an example of this approach, in that it has permitted a relatively low-cost upgrade which increases performance significantly. The technology assessment was completed in 1975, and the option was exercised in 1986, when needed. Several key characteristics of the DSN design approach, the costs to upgrade performance over the past several decades, and some fundamental constraints on performance are discussed. Finally, the specific 70-Meter upgrade task and resulting overall benefits to Voyager-Neptune and the mission set are summarized.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
