This study provides a single-point position estimation technique for interplanetary missions
by observing visible planets using star trackers. Closed-form least-squares solution is …

This paper presents a novel approach to identify, localize, and associate resident space
objects (ie Earth-orbiting satellites) across a series of unresolved optical images, to serve as …

Star centroiding, locating the star image center in a CCD image, is a fundamental process
for any star tracker. In this paper, the approximate location of the stars in successive image …

During astronomical observation, the centroiding of space targets is a crucial technology for
improving trajectory association in images, celestial positioning, and orbit determination …

This paper presents the first part of a demonstration on “How to use Star Trackers to perform
Space Surveillance”. This part shows how to simulate the image taken by a Star Tracker …

Streaked point sources are a common occurrence when imaging unresolved space objects
from both ground-and space-based platforms. Effective localization of streak endpoints is a …

The localization of the center of the star image formed on a sensor array directly affects
attitude estimation accuracy. This paper proposes an intuitive self-evolving centroiding …

Angles-only initial orbit determination (AIOD) methods have been used to find the orbit of
satellites since the beginning of the Space Race. Given the ever increasing number of …

This paper presents a generalized method of observation, association, and orbit
determination of space objects from one or more observers equipped with optical cameras …

Parametric uncertainty is one of many possible causes of divergence for the Kalman filter.
Frequently, state estimation errors caused by imperfect model parameters are reduced by …
