František Dráček:
Anomaly detection from TLE data

The rapidly growing number of objects in the Low Earth Orbit presents a significant challenge for satellite operators to ensure that satellites do not collide with other objects, which could lead to the loss of the satellite, or worse, it could cause the shattering of the satellites. A significant research effort is devoted to assessment of close conjunction close conjunction risks. Most such approaches rely on Two line element data (TLE). TLEs contains orbital elements of space object at a specific time. Aside from estimating collision risks, TLEs are used to calculate re-entry, used for drag make-up and space weather estimation. Our aim is to identify and study anomalies in the TLE data. The anomalies are in some cases related to the errors in the measurement, but also errors caused by their osculating(averaged) character.
