Available in PDF, EPUB and Kindle. Book excerpt: Low Earth Orbit Satellite constellations have begun to provide consumers with internet access in remote and under-served areas. Firms have begun to manufacture satellites at a higher rate than ever seen before in the aerospace industry. These satellites require environmental qualification testing to meet the standards required to launch and operate in space. For a new product, it is unclear how much testing capability will be necessary. This paper will provide an in-depth look at efforts to estimate the correct capital expenditure for the purposes of environmental testing for satellite manufacturing. It uses uncertainty analysis and parametric studies to compare options for precision manufacturing in an unknown field of production. The study finds that testing machine requirements vary through different periods of production, challenging the producer to purchase more capacity than will ultimately be necessary. These results highlight the need to develop failure rate predictions at the lowest component level to accurately assess testing requirements for the overall system.

Download or read book Satellite Observations of the Earth s Environment written by National Research Council and published by National Academies Press. This book was released on 2003-07-03 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report addresses the transition of research satellites, instruments, and calculations into operational service for accurately observing and predicting the Earth's environment. These transitions, which take place in large part between NASA and NOAA, are important for maintaining the health, safety, and prosperity of the nation, and for achieving the vision of an Earth Information System in which quantitative information about the complete Earth system is readily available to myriad users. Many transitions have been ad hoc, sometimes taking several years or even decades to occur, and others have encountered roadblocksâ€"lack of long-range planning, resources, institutional or cultural differences, for instanceâ€"and never reached fruition. Satellite Observations of Earth's Environment recommends new structures and methods that will allow seamless transitions from research to practice.
Download or read book From Research to Operations in Weather Satellites and Numerical Weather Prediction written by National Research Council and published by National Academies Press. This book was released on 2000-09-07 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This workshop report examines the capability of the forecast system to efficiently transfer weather and climate research findings into improved operational forecast capabilities. It looks in particular at the Environmental Modeling Center of the National Weather Service and environmental observational satellite programs. Using these examples, the report identifies several shortcomings in the capability to transition from research to operations. Successful transitions from R&D to operational implementation requires (1) understanding of the importance (and risks) of the transition, (2) development and maintenance of appropriate transition plans, (3) adequate resource provision, and (4) continuous feedback (in both directions) between the R&D and operational activities.
Download or read book Utilization of Operational Environmental Satellite Data written by National Research Council and published by National Academies Press. This book was released on 2005-01-21 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: The system of satellites in place to provide environmental data-data to monitor events such as forest fires and floods; to make weather predictions; and to assess crops, transportation impacts, fisheries, land-use patterns, sea temperature, and soil moisture, among other things- serves a wide and growing array of users. In the coming years as the next generation of operational environmental satellites in put in orbit, the will be a large expansion in data availability. To ensure that these data serve effectively this broad user community, a new vision for the future of operational environmental satellite data utilization is needed. To help develop approaches for handling this potential data overload, NASA, with technical support from NOAA, asked the NRC to conduct an end-to-end review of issues about the utilization of operational environmental satellite data for 2010 and beyond. This report presents the result of that review. It focuses on ensuring the value of environmental satellite data for addressing specific user needs, distribution of such data, and data access and utilization.

Download or read book Environmental Testing of the Petite Amateur Navy Satellite PANSAT written by Paul J. Overstreet and published by . This book was released on 1997-12-01 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Any complex and expensive system requires testing to ensure adequate performance. Communications satellites require extensive testing for two additional reasons: (1) they operate in an environment considerably different from that in which they were built, and (2) after launch, they are inaccessible to routine maintenance and repair. The objectives of testing is not necessarily to duplicate the space environment but to approach it sufficiently so that any spacecraft that passes the tests will operate successfully in its designed space environment. The major features of the space environment that are difficult to simulate exactly are zero gravity, high vacuum, solar radiation, particle radiation and extreme temperatures. This document describes the environmental test program and test results for the PANSAT program. PANSAT is the acronym for the Petite Amateur Navy Satellite, which is a small communications satellite under development by the Space Systems Academic Group at the Naval Postgraduate School. PANSAT subsystems were subjected to thermal vacuum and random vibration testing as part of the overall environmental test program. Satellite launch, as a Shuttle secondary payload via the Space Transportation System (STS) Small Self-contained Payload (SSCP) program, is planned for October, 1998.

Available in PDF, EPUB and Kindle. Book excerpt: The National Polar-Orbiting Environmental Satellite System (NPOESS) is a tri-agency acquisition -- managed by the DoD & NASA -- which experienced escalating costs, schedule delays, & technical difficulties. These factors led to a June 2006 decision to restructure the program, thereby decreasing the program¿s complexity, increasing its estimated cost to $12.5 billion, & delaying the first two satellites by 3 to 5 years. The author was asked to: (1) assess progress in restructuring the acquisition; (2) evaluate progress in establishing an effective mgmt. structure; (3) assess the reliability of the cost & schedule estimate; & (4) identify the status & key risks facing the program¿s major segments. Includes recommendations. Charts & tables.
