Next-generation Space Object Radar Tracking Simulator: SORTS++ [PDF]

, 2019
We describe the software toolbox SORTS++ which is the next-generation Space Object Radar Tracking Simulator (SORTS). This toolbox is able to simulate general Space Surveillance and Tracking (SST) applications from catalogue maintenance to cold-start ...

Approaches for astrometry using event-based sensors

, 2018
Event-based sensors are novel optical imaging devices that offer a different paradigm in which to image space and resident space objects. Also known as silicon retinas, these custom silicon devices make use of independent and asynchronous pixels which ...

Feature-based object tracking in maritime scenes.

A monitoring of presence, location and activity of various objects on the sea is essential for maritime navigation and collision avoidance. Mariners normally rely on two complementary methods of the monitoring: radar and satellite-based aids and human ...

Space Surveillance with High-Frequency Radar

High-Frequency (HF) radar is well suited to the surveillance of low-earth-orbit space. For large targets, a small deployable HF radar is able to match the detection performance of much larger space surveillance radar systems operating at higher ...

Improvement of a Space Surveillance Tracking Analysis Tool

, 2018
Since the beginning of space exploration, the amount of space debris has increased with thedevelopment of new space technologies. In fact, when a collision happens, new space debris aregenerated. Hence, collision risk between space debris and operational

Performance Analysis of Orbit Determination Algorithms for Space Surveillance & Tracking in LEO

, 2020
Space Surveillance and Tracking (SST) is an increasingly necessary field of research due to the exponential growth of debris. During this thesis several space environments are going to be simulated while surveillance and tracking is performed.
