Resident Space Object (RSO) Tracking in Space-Based, Low Resolution, Non-Constant-Attitude Imagery

Remote Sensing
Resident Space Objects (RSOs) are a collection of both man-made and natural objects in near-Earth space. Given their large orbital velocities and rapidly increasing quantity, they pose a collision threat to space assets, necessitating better Space ...

Technology Demonstration of Space Situational Awareness (SSA) Mission on Stratospheric Balloon Platform

Remote Sensing
As the number of resident space objects (RSOs) orbiting Earth increases, the risk of collision increases, and mitigating this risk requires the detection, identification, characterization, and tracking of as many RSOs as possible in view at any given ...

Enhancing the Capability of a Ground-Based Optical Telescope for Thai National Space objects Observation ^†

Proceedings, 2020
Nowadays, the space operations environment have to face with space safety problems because of the growing of space debris in resident of space objects (RSOs) that can cause a catastrophic collision. In order to prevent debris-related risks in operational
