Book Synopsis Method for the Calculation of Spacecraft Umbra and Penumbra Shadow Terminator Points by : Carlos R. Ortiz Longo
Download or read book Method for the Calculation of Spacecraft Umbra and Penumbra Shadow Terminator Points written by Carlos R. Ortiz Longo and published by . This book was released on 1995 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for calculating orbital shadow terminator points is presented. The current method employs the use of an iterative process which is used for an accurate determination of shadow points. This calculation methodology is required, since orbital perturbation effects can introduce large errors when a spacecraft orbits a planet in a high altitude and/or highly elliptical orbit. To compensate for the required iteration methodology, all reference frame change definitions and calculations are performed with quaternions. Quaternion algebra significantly reduces the computational time required for the accurate determination of shadow terminator points.

Book Synopsis Practical Methods for Optimal Control Using Nonlinear Programming, Third Edition by : John T. Betts
Download or read book Practical Methods for Optimal Control Using Nonlinear Programming, Third Edition written by John T. Betts and published by SIAM. This book was released on 2020-07-09 with total page 748 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do you fly an airplane from one point to another as fast as possible? What is the best way to administer a vaccine to fight the harmful effects of disease? What is the most efficient way to produce a chemical substance? This book presents practical methods for solving real optimal control problems such as these. Practical Methods for Optimal Control Using Nonlinear Programming, Third Edition focuses on the direct transcription method for optimal control. It features a summary of relevant material in constrained optimization, including nonlinear programming; discretization techniques appropriate for ordinary differential equations and differential-algebraic equations; and several examples and descriptions of computational algorithm formulations that implement this discretize-then-optimize strategy. The third edition has been thoroughly updated and includes new material on implicit Runge–Kutta discretization techniques, new chapters on partial differential equations and delay equations, and more than 70 test problems and open source FORTRAN code for all of the problems. This book will be valuable for academic and industrial research and development in optimal control theory and applications. It is appropriate as a primary or supplementary text for advanced undergraduate and graduate students.
Book Synopsis ACS Without an Attitude by : Harold L. Hallock
Download or read book ACS Without an Attitude written by Harold L. Hallock and published by Springer. This book was released on 2017-05-03 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book de-emphasizes the formal mathematical description of spacecraft on-board attitude and orbit applications in favor of a more qualitative, concept-oriented presentation of these topics. The information presented in this book was originally given as a set of lectures in 1999 and 2000 instigated by a NASA Flight Software Branch Chief at Goddard Space Flight Center. The Branch Chief later suggested this book. It provides an approachable insight into the area and is not intended as an essential reference work. ACS Without an Attitude is intended for programmers and testers new to the field who are seeking a commonsense understanding of the subject matter they are coding and testing in the hope that they will reduce their risk of introducing or missing the key software bug that causes an abrupt termination in their spacecraft’s mission. In addition, the book will provide managers and others working with spacecraft with a basic understanding of this subject.
Book Synopsis Apollo 14 by : Manned Spacecraft Center (U.S.)
Download or read book Apollo 14 written by Manned Spacecraft Center (U.S.) and published by . This book was released on 1971 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Apollo 14, the third mission during which men have worked on the surface of the Moon, was highly successful. This mission to the Fra Mauro Formation provided geophysical data from a new set of instruments... Because of improved equipment, such as the modularized equipment transporter, and because of the extended time spent on the lunar surface, a large quantity and variety of lunar samples were returned to Earth for detailed examination. New information concerning the mechanics of the lunar soil was also obtained during this mission. In addition, five lunar-orbital experiments were conducted during the Apollo 14 mission, needing no new equipment other than a camera. The experiments were executed by the command module pilot in the command and service module while the commander and the lunar module pilot were on the surface of the Moon. This report is preliminary in nature; however, it is meant to acquaint the reader with the actual conduct of the Apollo 14 scientific mission and to record the facts as they appear in the early stages of the scientific mission evaluation. As far as possible, data trends are reported, and preliminary results and conclusions are included."--p. xi.

Book Synopsis Thermospheric Density and Wind Determination from Satellite Dynamics by : Eelco Doornbos
Download or read book Thermospheric Density and Wind Determination from Satellite Dynamics written by Eelco Doornbos and published by Springer Science & Business Media. This book was released on 2012-01-19 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth's atmosphere is often portrayed as a thin and finite blanket covering our planet, separate from the emptiness of outer space. In reality, the transition is gradual and a tiny fraction of the atmophere gases is still present at the altitude of low orbiting satellites. The very high velocities of these satellites ensure that their orbital motion can still be considerably affected by air density and wind. This influence can be measured using accelerometers and satellite tracking techniques. The opening chapters of this thesis provide an excellent introduction to the various disciplines that are involved in the interpretation of these observations: orbital mechanics, satellite aerodynamics and upper atmospheric physics. A subsequent chapter, at the heart of this work, covers advances in the algorithms used for processing satellite accelerometry and Two-Line Element (TLE) orbit data. The closing chapters provide an elaborate analysis of the resulting density and wind products, which are generating many opportunities for further research, to improve the modelling and understanding of the thermosphere system and its interactions with the lower atmosphere, the ionosphere-magnetosphere system and the Sun.
