It is a comparatively convenient technique to investigate the motion of a particle with the help of the differential geometry theory, rather than directly decomposing the motion in the Cartesian… (More)
An overview of the space object orbit prediction error is presented, the propagation methods of orbit prediction error based on orbit models are given, and so are the propagation methods based on… (More)
Derivations of several explicit expressions of the collision probability under circular and ordinary orbital conditions through analysis of approaching distance are presented, so as to have the… (More)
Abstract When engaging in the maximum collision probability ( P c max ) analysis for short-term conjunctions between two orbiting objects, it is important to clarify and understand the assumptions… (More)
An introduction to the analytical and numerical methods commonly applied to the space object approaching analysis is unfolded.
An error analysis method based on historical orbital data is introduced, the periodic characteristics of the orbit prediction error are presented, and the error fitting is done by bringing in the… (More)
Orbital anomaly and space event detection methods based on historical orbital data and assessments on such methods are illustrated.
