Satellite Constellations. OneWeb’s constellation for global broadband internet coverage as part of the new space economy in low Earth orbit. Multiple such constellations are planned over the next decade. Sustaining the space economy will require development of new technologies for safe operations.
Space Debris. Significant amount of debris objects have collected in orbit over the years of space exploration that now pose a threat to operational spacecraft. Space traffic management for the future space economy will require active consideration of the space debris environment.
Collision uncertainty. In orbit collision avoidance requires accurate knowledge of an object’s state and the associated uncertainty. New models and methods are required for accurate prediction and determination of the state and characterization of the uncertainty.
