PairWatch spots adversarial satellite rendezvous in public catalogs
Original title: PairWatch: Pair-Aware Anomaly Transformer for Detecting Adversarial Rendezvous in Public Satellite Catalogs
Only PairWatch kept one threshold that separated real rendezvous from operational negatives in every bootstrap resample.
PairWatch is a pair-aware Anomaly Transformer for finding adversarial rendezvous and proximity operations in public two-line element catalogs. Its attention prior adds sign-symmetric geometric similarity over relative-motion features. On an open benchmark of 359 Space-Track windows, only PairWatch separated documented events from operational negatives under one threshold, in 100% of bootstrap resamples. Simpler baselines scored higher AUROC by exploiting a synthetic-versus-formation shortcut.
- The benchmark contains 359 windows from public Space-Track data.
- It includes 11 documented RPO events and 100 synthetic adversarial windows.
- PairWatch held the separation in 100% of bootstrap resamples.
- Three neural baselines succeeded in 0-19.5% of resamples.

From the original article
1 min read at arxiv.orgDocumented adversarial rendezvous and proximity operations (RPO) appear in the public TLE catalog, yet existing TLE-based maneuver detectors treat each satellite in isolation - mistaking routine station-keeping for adversarial behavior and missing RPO entirely when the target stays passive.
