abstract={Over-the-Air (OTA) software updates are essential for satellite security and reliability, yet limited uplink bandwidth and communication windows make them challenging. This work performs the first comparative analysis of bsdiff4, bsdiff6, bsdiff-ra, and HDiffPatch on a dataset representative of satellite software stacks, reconstructing a bsdiff6 implementation to enable bandwidth-efficient OTA updates.},
