RSONAR: Data-Driven Evaluation of Dual-Use Star Tracker for Stratospheric Space Situational Awareness (SSA) [PDF]

open access: yesSensors
The growing density of Earth-orbiting objects demands improved Space Situational Awareness (SSA) to mitigate collision risks and sustain space operations. This study demonstrates a dual-purpose star tracker (ST) for SSA using data from the Resident Space

Integrated Space Situational Awareness Systems: SDA and SSA – Advantages and Limitations

open access: yesPolish Political Science Yearbook, 2021
SDA (Space Domain Awareness) and SSA (Space Situational Awareness – SSA) have been defined as comprehensive knowledge of space objects and the ability to track, understand, and predict their future location.

SCT2G: Model for Fast Satellite Activity Recognition in SDA

open access: yesIEEE Access, 2022
With the rapid development of space technology, the space domain environment has become increasingly complex and variable, which has created more challenges for space domain awareness. By classifying the problems faced by SDA, the overall idea of solving

Prediction and Image Formation for Serendipitous Resident Space Object Underflights of Landsat 8

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Non-Earth imaging (NEI) of resident space objects (RSO) has become more readily available recently due to an expanding commercial sector focusing specifically on the NEI task, as well as high spatial resolution Earth imaging systems being agile enough to

Adaptive quantum accelerated imaging for space domain awareness

open access: yesNew Journal of Physics
The growth in space activity has increased the need for Space Domain Awareness (SDA) to ensure safe space operations. Imaging and detecting space targets is, however, challenging due to their dim appearance, small angular size/separation, dense ...

Ionospheric Vertical Total Electron Content Measurements Using VHF Radar Observations of Starlink Satellites

open access: yesRemote Sensing
There is increasing interest in space domain awareness (SDA), motivating the use of non-traditional sensors for space surveillance. One such sensor is the Buckland Park Stratospheric–Tropospheric (BPST) very high frequency (VHF) radar, which has ...
