The most widely-used data for civilian Space Situational Awareness are the Two-Line
Element sets (TLEs) provided by the USSTRATCOM. TLEs play critical roles in space …

Spent rocket bodies in geostationary transfer orbit (GTO) pose impact risks to the Earth's
surface when they reenter the Earth's atmosphere. To mitigate these risks, reentry prediction …

Predicting re-entry epoch of space objects enables managing the risk to ground population.
Predictions are particularly difficult for objects in highly-elliptical orbits, and important for …

The continuation of space activities is at risk due to the growing number of uncontrolled
objects, called space debris, which can collide with operational spacecraft. In addition …

Atmospheric density modeling and uncertainty quantification for fast and accurate orbit
propagation are vital to drag force estimation for satellite reentry prediction and conjunction …

Derelict satellites, rocket bodies, and pieces thereof have been left on orbit. These space
debris have been increasing in numbers and simulations of their future evolution have …

The ballistic coefficient is an important source of error in the orbit prediction of non-
cooperative targets. For a large number of non-cooperative targets, calculating quickly the …

Nowadays, satellite remote sensing technology has been applied in many fields of socio-
economic development, including search and rescue at sea. Systems with the integration of …
