Book Synopsis Orbit Determination of Satellite "Tance 1" with VLBI Data by : Xiao-gong Hu
Download or read book Orbit Determination of Satellite "Tance 1" with VLBI Data written by Xiao-gong Hu and published by . This book was released on 2006 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The satellite 'Tance 1' of the 'Double-Star Program' is the first truly scientific experimentation satellite of China. Its orbit is the farthest so far launched in China, with a geocentric apogee reaching 78 thousand kilometers. The tracking of 'Tance 1' and of more distant space targets, such as the lunar exploration craft, can be realized with the VLBI technique of radio astronomy. In order to test and verify the role which the VLBI technique plays in the lunar exploration program of China, Shanghai Astronomical Observatory organized the only 3 tracking stations in China (located at Shanghai, Urumqi and Kunming), to carry out test tracking of 'Tance 1,' and used the time delay data obtained to determine the orbit of 'Tance 1' over a two-day period, so providing a preliminary assessment of the possibility of VLBI orbit determination. The fitting error of the orbit so obtained is about 5.5 m in the time delay and about 2 cm/s in the delay rate (this for checking only), much better than is provided by the preliminary orbit (used merely for ensuring tracking) in which the corresponding figures are around 2 km and 15 cm/s. Further, if the orbit is determined by using both the time delay and time delay rate data (with weights according to their internal accuracies), then the residuals are 5.5 m in the time delay and 2 cm/s in the delay rate. For an appreciation of the true accuracy of the VLBI orbit determination, we used simulation data (of the observed two-day VLBI data) and found the results depended greatly on the error in the dynamic model of the satellite which, however, is difficult to assess, while the formal residuals are of the order of 1 kin in the delay and of cm/s in the delay rate. The simulation computation also indicates that a joint determination using both VLBI and USB data will have an improved accuracy."

Book Synopsis Orbit Determination and Analysis by : COSPAR. Scientific Assembly
Download or read book Orbit Determination and Analysis written by COSPAR. Scientific Assembly and published by Elsevier Science & Technology. This book was released on 1997 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paperback. This publication contains the proceedings of the meetings of the COSPAR Technical Panel on Satellite Dynamics which took place during the 31st Cospar Scientific Assembly held in Birmingham (UK) in July 1996. The 20 papers cover a variety of topics relating mainly to satellite orbit determination and analysis. A group of papers discusses orbit determination of low earth orbiters, in particular earth observation and research missions having high accuracy and using various various types of tracking support (data relay satellites, PRARE, laser, GPS). Two papers on geostationary orbits describe a project for their use in time-transfer and their evolution with time. Modelling problems associated with surface forces are analysed by a number of authors (an overview paper on Lageos perturbation models; the impact of surface forces on gravity models covering penumbra affects, numerical integration and attitude motion). One paper describes a visualisation

Book Synopsis Computation of Satellite Orbits by the Hansen Method as Modified by Musen by : Howard T. Phelan
Download or read book Computation of Satellite Orbits by the Hansen Method as Modified by Musen written by Howard T. Phelan and published by . This book was released on 1962 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive description of the Hansen theory of satellite orbit calculation, as modified by Musen, is presented. The equations of the theory are developed in sufficient detail to allow the reader to relate them to fundamental laws of celestial mechanics. The physical and mathematical concepts underlying Hansen's coordinate system and auxiliary ellipse are treated. The disturbing potential function and its derivatives are developed in the derivation of equations for the perturbations in the orbit plane, as well as the perturbations of the orbit plane. The method is described for determination of the final position and velocity vectors of the real satellite and determination of the osculating elements. Finally, a brief evaluation of the theory is presented.
