Book excerpt: While navigation systems for the determination of the orbit of the Global Position System (GPS) have proven to be very effective, the current issues involve lowering the error in the GPS satellite ephemerides below their current level. In this document, the results of an orbit determination covariance assessment are provided. The analysis is intended to be the baseline orbit determination study comparing the benefits of adding laser ranging measurements from various numbers of ground stations. Results are shown for two starting longitude assumptions of the satellite location and for nine initial covariance cases for the GPS satellite state vector. Welch, Bryan W.

Download or read book Algorithm Research on Orbit Determination for Low Orbit Satellites Using GPS. written by and published by . This book was released on 1996 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed discussions are made of principles and methods associated with orbital determinations for low orbit spacecraft making use of GPS systems. Analysis is done of problems which should be considered with regard to low orbit spacecraft during selection of satellites. In conjunction with this, satellite selection tests are carried out on the basis of navigation satellite as well as user models. Discussions are made of making use of least square methods to make calculations to determine orbits. Detailed analysis is done of Kalman filter algorithms. With a view to low orbit spacecraft, a nine state Kalman wave filter model is put forward. In conjunction with this, simulation analog calculations are carried out on this foundation. Besides this, on the basis of special user requirements with regard to electric power source energies and reliability, one type of relatively practical orbit determination method is put forward. Simulation results clearly show that the method put forward satisfies user requirements in terms of accuracy and is appropriate for actual engineering applications.

This book was released on 2006 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: During the last decade, numerous Low Earth Orbit (LEO) satellites, including TOPEX/POSEIDON, CHAMP and GRACE, have been launched for scientific purposes at altitudes ranging from 400 km to 1300 km. To support GPS meteorology, efficient LEO orbit determination methods were developed using the triple-differenced GPS phase observations. These methods include the kinematic, dynamic, and reduced-dynamic approach based on the wave algorithm. To test the developed algorithms, 24 hours of CHAMP data on February 15, 2003, which amounts to 15 revolutions, were used for each method. Precise IGS orbits are used for the GPS satellites, and 43 IGS ground tracking stations were chosen using the algorithm developed in this study, based on the network optimization theory. The estimated orbit solutions were compared with the published Rapid Science Orbit (RSO) and the consistency testing was performed for the dynamic solution. In addition, the SLR residuals were also computed as an independent validation of the methods presented here. After the forward and backward filtering, the kinematic approach shows accuracy better than "20 cm in 3D RMS for a half day arc compared to the reference RSO. With this careful modeling, the dynamic solution shows an agreement within "8 cm in position and "0.12 mm/s in velocity of RSO. The computation time of the dynamic solution for the 24-hour arc is 2.5 hours on a 3 GHz PC platform. The wave algorithm shows a better fit to RSO for each tested segment. However, there is slightly larger bias in its solution, thus, the overall RMS of fit is comparable to the dynamic orbit solution. The CHAMP orbit is successfully estimated in this study to support, for example, the GPS meteorology, using a new method that is accurate as well as fast and efficient. The hypothesis testing indicates that the estimated dynamic solution of this study is consistent with the published RSO. Also, the SLR residual test shows that the CHAMP orbit solution estimated in this study is comparable to solutions determined by other analysis centers, such as JPL and GFZ.

Book Synopsis Precise Geodetic Infrastructure by : National Research Council
Download or read book Precise Geodetic Infrastructure written by National Research Council and published by National Academies Press. This book was released on 2010-10-25 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geodesy is the science of accurately measuring and understanding three fundamental properties of Earth: its geometric shape, its orientation in space, and its gravity field, as well as the changes of these properties with time. Over the past half century, the United States, in cooperation with international partners, has led the development of geodetic techniques and instrumentation. Geodetic observing systems provide a significant benefit to society in a wide array of military, research, civil, and commercial areas, including sea level change monitoring, autonomous navigation, tighter low flying routes for strategic aircraft, precision agriculture, civil surveying, earthquake monitoring, forest structural mapping and biomass estimation, and improved floodplain mapping. Recognizing the growing reliance of a wide range of scientific and societal endeavors on infrastructure for precise geodesy, and recognizing geodetic infrastructure as a shared national resource, this book provides an independent assessment of the benefits provided by geodetic observations and networks, as well as a plan for the future development and support of the infrastructure needed to meet the demand for increasingly greater precision. Precise Geodetic Infrastructure makes a series of focused recommendations for upgrading and improving specific elements of the infrastructure, for enhancing the role of the United States in international geodetic services, for evaluating the requirements for a geodetic workforce for the coming decades, and for providing national coordination and advocacy for the various agencies and organizations that contribute to the geodetic infrastructure.
