A general perturbation solution to a restricted low-thrust Lambert rendezvous problem,
considering circular-to-circular in-plane maneuvers using tangential thrust and including a …

This paper presents an overview of space mission concepts for disrupting or pulverizing
hazardous asteroids, especially with warning time shorter than approximately 10 years. An …

This paper provides an alternative Lambert solution based on the terminal velocity vector.
The chordal terminal velocity component is selected as the independent variable since it is …

Lambert's problem is the two-point boundary-value problem resulting from a two-body orbital
transfer between two position vectors in a given time. It lies at the very heart of several …

An analytical linear covariance prediction is formulated for Lambert's boundary value
problem with navigation errors. The required initial velocity impulse in orbit targeting …

In this study, a supervised machine learning approach called Gaussian process regression
(GPR) was applied to approximate optimal bi-impulse rendezvous maneuvers in the cis …

A ground-based electro-optical (EO) array, deployed at the Jilin Space Tracking Base of
Changchun Observatory, China, has been in operation since April 2017. The array has 8 …

Fast and accurate collision probability computations are essential for protecting space
assets. Monte Carlo (MC) simulation is the most accurate but computationally intensive …

Design of the transfer from lunar orbits to the sun–Earth libration point region by direct
searching in the high-fidelity ephemeris model is an accurate but time-consuming practice. A …

Lambert's problem plays a significant role in preliminary design phases of many space
missions. In this paper, an analysis of techniques for the solution of Lambert's problem on …
