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.
