Numerous methods exist for solving the Lambert problem, the two-point boundary value
problem (BVP) governed by two-body dynamics. Many applications would benefit from a …

A critical challenge in Space Domain Awareness (SDA) is gaining custody of newly detected
or maneuvering objects. The dynamically feasible location of one such object may be …

As space object populations in the near-Earth and cislunar regimes exponentially grow,
increased supervision of the near-Earth environment is critical to space sustainability …

TRACKING a CubeSat cluster deployment is a challenging endeavor. Technology
miniaturization is motivating a growing interest in CubeSats, which in turn creates a market …

摘要天基光学监测可以有效弥补地基设备监测空间碎片频次低的问题. 为了提升天基光学监测下
初始轨道确定的收敛性与计算效率, 构建一种扩展目标函数模型, 提出在距离 …

With the continuous increase in the number of space objects and limitations imposed by
observation conditions, a significant number of short-arc observations, namely tracklets, are …

Hundreds of too-short tracklets of angular measurements, which cannot be correlated to
known catalogue objects, are usually obtained by an operation optical network every night …

Abstract In the Initial Orbit Determination (IOD) context, Admissible Regions are subsets of
parameter space of orbital elements that are reckoned as functions of the tracking …

In optical tracking scenarios for Resident Space Objects (RSOs), the observing arcs are
usually sparse and short, resulting in failure of initial orbit determination using single tracks …

For a variety of mission-critical objectives in Space Domain Awareness (SDA), it is relevant
to maintain estimates over large regions of state space using highly non-Gaussian …
