Available in PDF, EPUB and Kindle. Book excerpt: Low-earth orbit satellite constellations provide important services over very large areas in a uniform way. Traditional spacecraft communication typically requires manually-staffed ground stations with space systems experts controlling and monitoring bus and payload systems during each pass. These onerous requirements limit the ability to access valuable space assets, more so in the case of large constellations of satellites. This thesis presents a virtual ground station (VGS) with a real-time virtual satellite model (VSM) and a fault-management system based on industrial statistical process control (SPC) techniques and time-domain feature extraction. The VSM is in continuous view of the VGS at all times and allows the operators to send and receive data as required without waiting for a pass. The operators always interact with the VSM through a graphical user interface (GUI) terminal as opposed to the spacecraft itself such that the VSM mimics the actual satellite as much as possible. The VGS streamlines spacecraft operations by managing every real pass, uploads stored commands when a pass occurs, automatically downloads telemetry and maintains the VSM. This eliminates trivial housekeeping activities and lets the experts focus on complex problems. The VGS also contains a real-time orbit propagator that provides the real-time position and velocity of the satellite and lets the operators visualize the mission in 3D. In this thesis, the VSM uses the power subsystem as an example and takes the form of a real-time power subsystem simulator of the spacecraft. The fault-management system employs custom algorithms to monitor telemetry from the spacecraft and compare it to the predicted telemetry from the VSM to perform early fault diagnosis. The specific faults considered are the loss of a solar string(s), increase in the battery's internal resistance and excessive power consumption onboard the spacecraft. A unique testbed consisting of a simulation engine with an actual satellite model (ASM) and a serial communication protocol is presented. It is used to demonstrate the functions of the VGS through various scenarios during a typical interaction between the VGS and the satellite. Some of these scenarios include initiation of communication with the spacecraft, automatic telemetry downloading, anomaly detection, real-time data requests and storing and uploading commands to the spacecraft.

Book Synopsis Autonomous and Autonomic Systems: With Applications to NASA Intelligent Spacecraft Operations and Exploration Systems by : Walt Truszkowski
Download or read book Autonomous and Autonomic Systems: With Applications to NASA Intelligent Spacecraft Operations and Exploration Systems written by Walt Truszkowski and published by Springer Science & Business Media. This book was released on 2009-11-12 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1990s, NASA Goddard Space Flight Center started researching and developing autonomous and autonomic ground and spacecraft control systems for future NASA missions. This research started by experimenting with and developing expert systems to automate ground station software and reduce the number of people needed to control a spacecraft. This was followed by research into agent-based technology to develop autonomous ground c- trol and spacecraft. Research into this area has now evolved into using the concepts of autonomic systems to make future space missions self-managing and giving them a high degree of survivability in the harsh environments in which they operate. This book describes much of the results of this research. In addition, it aimstodiscusstheneededsoftwaretomakefutureNASAspacemissionsmore completelyautonomousandautonomic.Thecoreofthesoftwareforthesenew missions has been written for other applications or is being applied gradually in current missions, or is in current development. It is intended that this book should document how NASA missions are becoming more autonomous and autonomic and should point to the way of making future missions highly - tonomous and autonomic. What is not covered is the supporting hardware of these missions or the intricate software that implements orbit and at- tude determination, on-board resource allocation, or planning and scheduling (though we refer to these technologies and give references for the interested reader).

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the basic concepts of spacecraft operations for both manned and unmanned missions. The first part of the book provides a brief overview of the space segment. The next four parts deal with the classic areas of space flight operations: mission operations, communications and infrastructure, the flight dynamics system, and the mission planning system. This is followed by a part describing the operational tasks of the various subsystems of a classical satellite in Earth orbit. The last part describes the special requirements of other mission types due to the presence of astronauts, the approach of a satellite to another target satellite, or leaving Earth orbit in interplanetary missions and landing on other planets and moons. The 2nd edition is published seven years after the first edition. It contains four new chapters on flight procedures, the human factors, ground station operation, and software and systems. In addition, several chapters have been extensively expanded. The entire book has been brought up to date and the language has been revised. This book is based on the “Spacecraft Operations Course” held at the German Space Operations Center. However, the target audience of this book is not only the participants of the course, but also students of technical and scientific courses, as well as technically interested people who want to gain a deeper understanding of spacecraft operations.

Book Synopsis Earth Observations from Space by : National Research Council
Download or read book Earth Observations from Space written by National Research Council and published by National Academies Press. This book was released on 2007-12-17 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 50 years, thousands of satellites have been sent into space on missions to collect data about the Earth. Today, the ability to forecast weather, climate, and natural hazards depends critically on these satellite-based observations. At the request of the National Aeronautics and Space Administration, the National Research Council convened a committee to examine the scientific accomplishments that have resulted from space-based observations. This book describes how the ability to view the entire globe at once, uniquely available from satellite observations, has revolutionized Earth studies and ushered in a new era of multidisciplinary Earth sciences. In particular, the ability to gather satellite images frequently enough to create "movies" of the changing planet is improving the understanding of Earth's dynamic processes and helping society to manage limited resources and environmental challenges. The book concludes that continued Earth observations from space will be required to address scientific and societal challenges of the future.
