Software Tools for Fault Management Technologies

Marshall Space Flight Center, Alabama Several key areas of improvement in effect design, development, verification, and validation of fault management processes have been identified in NASA’s Fault Management Handbook. The majority of these guidelines are focused on making the modeling tools more user friendly and reducing the modeling cost and time, as well as enhancing the analytic capabilities.

Tool to Analyze a Leaking Source of Saturated Ammonia

Lyndon B. Johnson Space Center, Houston, Texas Containers of ammonia are used to supply cooling to different modules of the International Space Station. Each container has an attachment piece used to extract the ammonia. The attachment piece may allow ammonia to exit when not connected, and may also allow ammonia to exit to an outside area even when connected. The ammonia that has exited the container may accumulate in different compartments of the spacecraft. The ammonia is not desirable when accumulated in a compartment with a certain concentration.

Mixed-Integer Convex Programming Algorithm for Constrained Attitude Guidance

NASA’s Jet Propulsion Laboratory, Pasadena, California A general problem in spaceflight since its beginning is attitude guidance: how to turn a spacecraft — also called a slew — so as to point science instruments at their targets. The slew must be done while avoiding pointing sensitive science instruments (e.g., a camera) and attitude sensors (e.g., a star tracker) at bright objects in the sky (e.g., the Sun or the Moon).

A Robust, Real-Time Collaboration Technology for Decision Support using Common Operating Picture (COP) Environments

This software provides remote geobrowser control for collaborative decision-making. Stennis Space Center, Mississippi StormCenter Communications, Inc. software takes advantage of cloud computing solutions to solve the growing need for real-time collaboration when accessing a Common Operating Picture (COP) from any device without having to give up all the vital tools and display functionality; all this is performed without disrupting current workflows. A COP is a platform shared by multiple stakeholders to provide a single, identical display of relevant operational information (i.e., mapping information, network operations and cyber security, sensors, weather, critical infrastructure) and tools to mark and manipulate the data. In the era of Big Data and the need for improved decision-making with the presence of multiple stakeholders across different disciplines, collaboration when using a COP is essential to success. This is especially important when dealing with decision-makers who are frequently non-data experts who need to take action immediately based on their situational awareness.

2016’s Best Practices for NPI and NPD Success

Smart companies know that well disciplined new product introduction (NPI) processes are critical to success. Yet, even these companies can suffer from NPI failure when important projects, policies, and guidelines are haphazardly managed as clumsy manual processes.

Executive Perspectives: Internet of Things

ALEX IUORIO Senior Vice President, Supplier Management and Business Development Avnet Electronics Marketing Americas Phoenix, AZ www.em.avnet.com In a 1926 interview, inventor Nikola Tesla stated: “When wireless [technology] is perfectly applied, the whole Earth will be converted into a huge brain.” Though Tesla’s remark was made four decades before the earliest incarnations of Internet technology were introduced by the U.S. Advanced Research Projects Agency, it is an uncanny depiction of the power and potential we see today from the Internet of Things (IoT).

Rigorous Antenna Noise Temperature Calculation Method for International Space Station Visiting Spacecraft

Lyndon B. Johnson Space Center, Houston, Texas The temperature of the orbiting space station’s Sun-facing side could be up to 250 °F (≈120 °C) and will be a significant antenna noise temperature contributor for visiting spacecraft communication and tracking systems during rendezvous. The conventional antenna noise temperature calculation does not take into account the space station reflection effects, and results in an underestimated antenna and system noise temperature. Thus, the visiting spacecraft communication and tracking system performance could be overestimated during rendezvous.
