This work presents a new method for space-based angles-only orbit estimation. The
approach relies on the integration of a novel and highly accurate Analytic Continuation …

This paper introduces a high-order nonlinear least-squares method for solving six-degree-of-
freedom (6-DOF) navigation of satellite maneuvers. The approach involves developing first …

Hypervelocity breakup events contribute to the rapidly growing population of space debris
orbiting Earth. To ensure a safe environment for future space missions, it is crucial to …

In this paper, a highly accurate and efficient Adaptive Local Variational Iteration Method
(ALVIM) is presented to fulfil the need of the astrodynamics society for fast and accurate …

In this work, the Taylor series based integration approach, Analytic Continuation, has been
implemented to compute Higher Order State Transition Tensors for the J 2-J 6 gravity and …

At present, most software testing in the industry starts from the code to generate test case
sets, and it is difficult to answer the question of whether the software meets the requirement …

ABSTRACT In Space Situational Awareness (SSA), accurate and efficient uncertainty
quantification and propagation are essential for various applications, such as conjunction …

This work aims to construct a new regularisation version for the perturbed two-body problem
using bipolar coordinates. We mainly use two transformation techniques to deal with this …

Although the dynamics of celestial orbits are often dominated by conservative gravitational
fields, the nonconservative forces can play a key role in their long-term behaviors. Therefore …
