abstract: >-
Nanosatellites increasingly produce more data than can be
downlinked within a reasonable time due to their limited
bandwidth and power. Therefore, an on-board system is
required to prioritize scientifically significant data for
downlinking, as described by scientists. This paper
determines whether natural language processing can be used
to prioritize remote sensing images on CubeSats with more
flexibility compared to existing methods. Two approaches
implementing the same conceptual prioritization pipeline
are compared. The first uses YOLOv8 and Llama2 to extract
image features and compare them with text descriptions via
cosine similarity. The second approach employs CLIP,
fine-tuned on remote sensing data, to achieve the same.
Both approaches are evaluated on real nanosatellite
hardware, the VERTECS Camera Control Board. The CLIP
approach, particularly the ResNet50-based model, shows the
best performance in prioritizing and sequencing remote
sensing images. This paper demonstrates that on-orbit
prioritization using natural language descriptions is
viable and allows for more flexibility than existing
methods.
