Geostationary Satellites Collocation aims to find solutions for deploying a safe and reliable collocation control. Focusing on the orbital perturbation analysis, the mathematical foundations for orbit and control of the geostationary satellite. The mathematical and physical principle of orbital maneuver and collocation strategies for multi geostationary satellites sharing with the same dead band is also stressed. Moreover, the book presents some applications using the above algorithms and mathematical models to help readers master the corrective method for planning station keeping maneuvers. Engineers and scientists in the fields of aerospace technology and space science can benefit from this book. Hengnian Li is the Deputy Director of State Key Laboratory of Astronautic Dynamics, China.

This book constitutes the proceedings of the Second International Conference on Space Information Network, SINC 2017, held in Yinchuan, China, in August 2017. The 27 full and three short papers presented in this volume were carefully reviewed and selected from 145 submissions. The papers are organized in topical sections on system architecture and efficient networking mechanism; theory and method of high speed transmission; sparse representation and fusion processing.
The focus of this thesis is a two-phase method for the solution of trajectory op- timization problems where a low-thrust ion engine is used for a many-revolution transfer from a low-Earth orbit to a geostationary orbit.

The focus of this thesis is a two-phase method for the solution of trajectory op- timization problems where a low-thrust ion engine is used for a many-revolution transfer from a low-Earth orbit to a geostationary orbit. The problem is formulated using a perturbation model in the modified equinoctial element set. Perturbations considered are that of a low-thrust ion propulsion source and a truncated spherical harmonic model for Earth's gravity. Extra consideration for Earth's umbral and penumbral regions is also presented. The formulation for both phase one as an in- direct optimal control problem and phase two as a direct optimal control problem is provided as well as an explanation of the Legendre-Gauss-Radau pseudospectral method used to find numerical solutions for the chosen test case. The test case used within this thesis is based on a test case provided in the recent literature by Betts . A simulation of the phase one problem, with an analysis on how to ob- tain the control curves is provided. All simulations were performed and solved in MATLAB using a nonlinear optimizer created by for this thesis and loosely based on code from Reference . The formulation for the phase one problem has pro- duced encouraging results for future research testing the derived control laws for spacecraft steering provided. The phase two direct optimization problem provides additional future work.

This book introduces readers to the application of orbital data on space objects in the contexts of conjunction assessment and space situation analysis, including theories and methodologies. It addresses the main topics involved in space object conjunction assessment, such as: orbital error analysis of space objects; close approach analysis; the calculation, analysis and application of collision probability; and the comprehensive assessment of collision risk. In addition, selected topics on space situation analysis are also presented, including orbital anomaly and space event analysis, and so on. The book offers a valuable guide for researchers and engineers in the fields of astrodynamics, space telemetry, tracking and command (TT&C), space surveillance, space situational awareness, and space debris, as well as for graduates majoring in flight vehicle design and related fields.

Since the start of the space age more than 50 years ago, various space technology applications - including communication, navigation, and remote sensing - have advanced significantly. To meet the challenges in each application category, special orbits such as geo-stationary, semi-synchronous, Molniya, sun-synchronous, and frozen have been invented or selected. Although a good number of texts on the principles and applications of astrodynamics have been published, a book is needed to summarize the perturbation theories and control, or station keeping, algorithms for understanding the dynamics, stability, and maintenance of those orbits. Applied Orbit Perturbations and Maintenance was written to meet that need. It summarizes, in appropriate technical and mathematical detail, perturbation theories and station keeping algorithms for various types of mission orbits and constellations. Space mission designers/analysts and systems engineers will put this book to great use.

This work offers a general & systematic collection of basic legal documents that will be a required tool for researchers & practitioners. Its looseleaf format ensures that it will remain up to date. Volume One, Part A contains principal legal instruments--the so-called 'classical instruments'--elaborated within the United Nations, & also includes a chapter on all space law disputes which have arisen up to the present. Part B deals with current problems. Volume Two, Part A deals with international organizations, Part B with international projects (short technical introductions precede the information about the present legal status in each case), & Part C deals with national legislation specifically concerning outer space issues. Each treaty & convention is followed by the status of each instrument, & each subchapter by a list of related basic legal literature. Space Law: Basic Legal Documents is regularly updated.
While the use of relative orbit determination has reduced the difficulties inherent in tracking geosynchronous satellites that are in close proximity, the problem is often compounded by stationkeeping operations or unexpected maneuvers.
