ASTRIANet: Optical Satellite Observations for Space Domain Awareness

ASTRIANet, a robotic telescope network operated by ASTRIA, provides optical observations of Anthropogenic Space Objects (ASOs) across LEO to GEO orbital regimes. The dataset contains FITS-formatted image files with annotations, including two full observation passes of a Starlink and a Navstar satellite over 5-minute and 11-minute periods. It serves as example data for demonstrating the PyCIS a-contrario detection and tracking algorithm, supporting the Space Domain Awareness mission of ASTRIAGraph.

Use Cases

• Testing object detection algorithms based on annotated FITS image data of satellites.
• Developing and validating tracking algorithms for time-series optical observations of space objects.
• Demonstrating the PyCIS a-contrario detection software using provided example data.
• Studying imaging and tracking noise characteristics in electro-optical observations for Space Domain Awareness.

Strengths

• Contains annotated FITS image data, providing ground truth for algorithm development.
• Includes two complete observation passes of specific satellites (Starlink-1422 and Navstar-48) over defined periods (5 and 11 minutes).
• Cross-platform presence on Dataverse and PapersWithCode suggests recognized utility for the research community.

Limitations

• Dataset size, row count, and specific column information are not provided by any source.
• One source lists 'Open Access (green)' license while another lists no license, creating a conflict.
• The dataset is described as an example of typical sensor capabilities, suggesting it may be a limited demonstration set rather than a large-scale collection.
