Download or read book NASA s Management of the Deep Space Network written by National Aeronautics and Space Administration and published by CreateSpace. This book was released on 2015-03-26 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA's Deep Space Network (DSN or Network) is a central component of the Agency's space communications and navigation capability, providing deep space missions with tracking, telemetry, and command services needed to control spacecraft and transmit data. Part of NASA's Space Communications and Navigation (SCaN) Program, DSN operates antennas and transmitters at communications complexes in three locations: Goldstone, California; Madrid, Spain; and Canberra, Australia. NASA has contracts with the Spanish and Australian governments to manage day-to-day operations at the foreign sites and with the Jet Propulsion Laboratory (JPL), a federally funded research and development center in Pasadena, California, for the Goldstone site. During fiscal year (FY) 2014, DSN supported more than 30 missions including the launch and orbit insertions of NASA's Mars Atmosphere and Volatile Evolution Mission and the Indian Space Agency's Mars Orbiter Mission. Much of DSN's hardware is more than 30 years old, costly to maintain, and requires modernization and expansion to ensure continued service for existing and planned missions. Accordingly, in 2009 DSN management proposed an upgrade project to build new antennas and transmitters between 2009 and 2025. DSN has significant information technology (IT) and physical infrastructure components that it must protect against compromise from cyber attack, espionage, and terrorism. To this end, the JPL, Madrid, and Canberra agreements require each contractor to follow specified Federal and NASA security policies. We conducted this audit to examine whether DSN is positioned to meet current and future communication commitments and appropriately managing Network IT and physical security risks. We also considered whether NASA is effectively administering the contracts relating to the foreign sites. Although DSN is meeting its current operational commitments, budget reductions have challenged the Network's ability to maintain these performance levels and threaten its future reliability. Specifically, in FY 2009 the Network implemented a plan to achieve $226.9 million in savings over 10 years and use most of that savings to build new antennas and transmitters. However, in FY 2013 the SCaN Program cut the Network's budget by $101.3 million, causing DSN to delay upgrades, close antennas, and cancel or re-plan tasks. In addition, SCaN officials are considering additional cuts for DSN in FY 2016 that could further delay maintenance and upgrade tasks. Finally, despite these reductions DSN has not revised life-cycle cost estimates for the upgrade project or performed a detailed funding profile beyond FY 2018, making it difficult to effectively plan and justify funding for the project and DSN's future commitments. If budget reductions continue, DSN faces an increased risk that it will be unable to meet future operational commitments or complete the upgrade project on schedule.

Download or read book War For The Spheres written by W. G. TUTTLE and published by W. G. Tuttle. This book was released on 2021-10-28 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: American Astronaut, Hayden Bakley, is an experienced space explorer. As many times as he had been into space, he did not know a quiet, yet, potentially life-altering war for the spheres is taking place all over the world. What if a country, group, or individual seized complete command and control of every orbiter encircling the globe, including space stations? The Outer Space Treaty provides a framework for preventing such seizures, but what if those principles were now thought of as being outdated? That the spheres around the Earth were no different from the land, there to be conquered and controlled. Hayden is drafted into the war for the spheres through no doing of his own. It is up to him and an under-the-radar NASA group to stop such a monopoly from being achieved. For whoever controls the spheres, controls Earth below and space beyond.

This book was released on 2005-02-18 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to antenna Arraying in the Deep Space network Antenna arraying is the combining of the output from several antennas in order to improve the signal-to-noise ratio (SNR) of the received signal. Now implemented at the Goldstone Complex and other Deep Space Network (DSN) overseas facilities, antenna arraying provides flexible use of multiple antennas to increase data rates and has enabled NASA's DSN to extend the missions of some spacecraft beyond their planned lifetimes. Antenna Arraying Techniques in the Deep Space Network introduces the development and use of antenna arraying as it is implemented in the DSN. Drawing on the work of scientists at JPL, this timely volume summarizes the development of antenna arraying and its historical background; describes key concepts and techniques; analyzes and compares several methods of arraying; discusses several correlation techniques used for obtaining the combined weights; presents the results of several arraying experiments; and suggests directions for future work. An important contribution to the scientific literature, Antenna Arraying Techniques in the Deep Space Network * Was commissioned by the JPL Deep Space Communications and Navigation Systems (DESCANSO) Center of Excellence * Highlights many NASA-funded technical contributions pertaining to deep space communications systems * Is a part of the prestigious JPL Deep Space Communications and Navigation Series The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields.
