Book Synopsis Satellite Orbits Estimation, Determination, and Control by : Mohamed Zayan
Download or read book Satellite Orbits Estimation, Determination, and Control written by Mohamed Zayan and published by LAP Lambert Academic Publishing. This book was released on 2010-10 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis analyzes and develops the methods of accurate satellite orbits determination and estimation using adaptive Least Mean Squares (LMS), Kalman digital filters, and Adaptive Neural Networks (ANN). In addition, the thesis develops and implements satellite orbits controllers using an Adaptive Neural Network Predictive Control (ANNPC) technique. After a spacecraft has been placed in an operational orbit about the Earth, it will lose its orbit due to physical perturbation forces from the Earth, the Sun, and the Moon. Subsequent thrusting maneuvers will be required to correct the satellite orbit. Orbit estimation and determination are required with high accuracy, which are the first and the most important phase in preparation of the satellite-control-maneuver. The thesis specifically addresses the algorithmic implementation of the LMS and Kalman filters for the spacecraft orbit determination and estimation problem. The inherent advantages, disadvantages and trade-off, which are required to select the suitable method, have been analyzed. The orbit determination and estimation has been refined using multi-layers ANN with a non-linear function.

Book Synopsis Determination of Precise Satellite Orbits and Geodetic Parameters using Satellite Laser Ranging by : Krzysztof Sośnica
Download or read book Determination of Precise Satellite Orbits and Geodetic Parameters using Satellite Laser Ranging written by Krzysztof Sośnica and published by Astronomical Institute, University of Bern, Switzerland. This book was released on 2014-04-07 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contribution of Satellite Laser Ranging (SLR) to the definition of the origin of the reference frame (geocenter coordinates), the global scale, and low degree coefficients of the Earth's gravity field is essential due to the remarkable orbit stability of geodetic satellites and the accuracy of laser observations at a level of a few millimeters. Considering these aspects, SLR has an exceptional potential in establishing global networks and deriving geodetic parameters of the supreme quality. SLR faces today the highest requirements of the Global Geodetic Observing System (GGOS) yielding 1 mm of long-term station coordinate and 0.1 mm/y of station velocity stability. The goal of this work is to assess the contribution of the latest models and corrections to the SLR-derived parameters, to enhance the quality and reliability of the SLR-derived products, and to propose a new approach of orbit parameterization for low orbiting geodetic satellites. The impact of orbit perturbations is studied in detail, including perturbing forces of gravitational origin (Earth's gravity field, ocean and atmosphere tides) and perturbing forces of non-gravitational origin (atmospheric drag, the Yarkovsky effect, albedo and Earth's infrared radiation pressure). A multi-satellite combined solution is obtained using SLR observations to LAGEOS-1, LAGEOS-2, Starlette, Stella, and AJISAI. The quality of the SLR-derived parameters from the combined solution is compared with external solutions. The Earth rotation parameters are compared to the IERS-08-C04 series and the GNSS-derived series, whereas the time variable Earth's gravity field coefficients are compared to the CHAMP and GRACE-derived results.

Available in PDF, EPUB and Kindle. Book excerpt: This book on space geodesy presents pioneering geometrical approaches in the modelling of satellite orbits and gravity field of the Earth, based on the gravity field missions CHAMP, GRACE and GOCE in the LEO orbit. Geometrical approach is also extended to precise positioning in space using multi-GNSS constellations and space geodesy techniques in the realization of the terrestrial and celestial reference frame of the Earth. This book addresses major new developments that were taking place in space geodesy in the last decade, namely the availability of GPS receivers onboard LEO satellites, the multitude of the new GNSS satellite navigation systems, the huge improvement in the accuracy of satellite clocks and the revolution in the determination of the Earth's gravity field with dedicated satellite missions.

Book Synopsis Continuing Kepler's Quest by : National Research Council
Download or read book Continuing Kepler's Quest written by National Research Council and published by National Academies Press. This book was released on 2012-09-06 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: In February 2009, the commercial communications satellite Iridium 33 collided with the Russian military communications satellite Cosmos 2251. The collision, which was not the first recorded between two satellites in orbit-but the most recent and alarming-produced thousands of pieces of debris, only a small percentage of which could be tracked by sensors located around the world. In early 2007, China tested a kinetic anti-satellite weapon against one of its own satellites, which also generated substantial amounts of space debris. These collisions highlighted the importance of maintaining accurate knowledge, and the associated uncertainty, of the orbit of each object in space. These data are needed to predict close approaches of space objects and to compute the probability of collision so that owners/operators can decide whether or not to make a collision avoidance maneuver by a spacecraft with such capability. The space object catalog currently contains more than 20,000 objects, and when the planned space fence radar becomes operational this number is expected to exceed 100,000. A key task is to determine if objects might come closer to each other, an event known as "conjunction," and the probability that they might collide. The U.S. Air Force is the primary U.S. government organization tasked with maintaining the space object catalog and data on all space objects. This is a complicated task, involving collecting data from a multitude of different sensors-many of which were not specifically designed to track orbiting objects-and fusing the tracking data along with other data, such as data from atmospheric models, to provide predictions of where objects will be in the future. The Committee for the Assessment of the U.S. Air Force's Astrodynamic Standards collected data and heard from numerous people involved in developing and maintaining the current astrodynamics standards for the Air Force Space Command (AFSPC), as well as representatives of the user community, such as NASA and commercial satellite owners and operators. Preventing collisions of space objects, regardless of their ownership, is in the national security interested of the United States. Continuing Kepler's Quest makes recommendations to the AFSPC in order for it to create and expand research programs, design and develop hardware and software, as well as determine which organizations to work with to achieve its goals.
