Available in PDF, EPUB and Kindle. Book excerpt: Complete characterization of the space environment in support of the United States goal of space Situational Awareness is not currently achievable. When confronted with recent increases in the deployment and miniaturization of microsatellites by numerous nations, the questions of foreign space capabilities are magnified. This study sought to determine the feasibility of and experimentally demonstrate a microsatellite capability to autonomously loiter about and track a target satellite. Various methods of passive remote sensing were investigated to determine the best means of detecting and tracking a target in space. Microbolometer-based infrared sensors were identified as the best alternative. A representative system was constructed for demonstration in AFIT s SIMSAT laboratory. Software modeling results identified open-loop instability, and therefore the requirement for closed-loop control. A simple PD control algorithm served as the basis for control, and a pseudo-feed-forward term was added to improve results. The feed-forward term was derived form orbital dynamics as the rate at which the chase satellite traverses around an ellipse formed in the target s frame of reference. Reduction in pointing errors of up to 67% were found in simulations. Successful non-optimal tracking results were obtained in the laboratory with a hardware-in-the-loop model for both step and moving inputs.
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).
Book Synopsis High-Reliability Autonomous Management Systems for Spacecraft by : Jianjun Zhang
Download or read book High-Reliability Autonomous Management Systems for Spacecraft written by Jianjun Zhang and published by Elsevier. This book was released on 2023-08-25 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-Reliability Autonomous Management Systems for Spacecraft updates on research on three levels of self-management, including: 1) Autonomous health management of spacecraft that covers how spacecraft can monitor their own state and autonomously detect, isolate and recover from faults; 2) Autonomous mission management of spacecraft where the spacecraft can directly receive the mission, formulate a reasonable plan according to the current state and working environment of the spacecraft, and convert the mission into a specific sequence of instructions; 3) Spacecraft autonomous data management where the spacecraft processes a large amount of raw data and extracts useful information, and autonomously executes or changes flights. The autonomous management of spacecraft uses modern control technologies such as artificial intelligence to establish a remote intelligent body on the spacecraft so that the spacecraft can complete its flight tasks by itself. Its goal is to accurately perceive its own state and external environment without relying on external information injection and control or rely on external control as little as possible. Divides the autonomous management level of spacecraft into two levels, autonomy and execution Covers the implementation of spacecraft autonomous management into three aspects, including autonomous health management of the spacecraft, mission management, and converting the mission into a specific sequence of instructions Discusses how these processes can take a large amount of raw data and extract useful information Covers the autonomous management model of the spacecraft, including compatibility

Book Synopsis Spacecraft Autonomous Navigation Technologies Based on Multi-source Information Fusion by : Dayi Wang
Download or read book Spacecraft Autonomous Navigation Technologies Based on Multi-source Information Fusion written by Dayi Wang and published by Springer. This book was released on 2021-08-02 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the fundamentals of estimation and dynamical system theory, and their applications in the field of multi-source information fused autonomous navigation for spacecraft. The content is divided into two parts: theory and application. The theory part (Part I) covers the mathematical background of navigation algorithm design, including parameter and state estimate methods, linear fusion, centralized and distributed fusion, observability analysis, Monte Carlo technology, and linear covariance analysis. In turn, the application part (Part II) focuses on autonomous navigation algorithm design for different phases of deep space missions, which involves multiple sensors, such as inertial measurement units, optical image sensors, and pulsar detectors. By concentrating on the relationships between estimation theory and autonomous navigation systems for spacecraft, the book bridges the gap between theory and practice. A wealth of helpful formulas and various types of estimators are also included to help readers grasp basic estimation concepts and offer them a ready-reference guide.

Available in PDF, EPUB and Kindle. Book excerpt: Satellites are used increasingly in telecommunications, scientific research, surveillance, and meteorology, and these satellites rely heavily on the effectiveness of complex onboard control systems. This 1997 book explains the basic theory of spacecraft dynamics and control and the practical aspects of controlling a satellite. The emphasis throughout is on analyzing and solving real-world engineering problems. For example, the author discusses orbital and rotational dynamics of spacecraft under a variety of environmental conditions, along with the realistic constraints imposed by available hardware. Among the topics covered are orbital dynamics, attitude dynamics, gravity gradient stabilization, single and dual spin stabilization, attitude maneuvers, attitude stabilization, and structural dynamics and liquid sloshing.

Available in PDF, EPUB and Kindle. Book excerpt: This paper addresses the design of pointing control systems for autonomous space vehicles. The function of the pointing control system is to keep distant orbiting objects within the field-of-view of an on-board optical sensor. We outline the development of novel nonlinear control algorithms which exploit the availability of on- board sensors. Simulation results comparing the performance of the different pointing control implementations are presented.
