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.
