SPOOK - A comprehensive Space Surveillance and Tracking analysis tool

Acta Astronautica, 2019
Space Surveillance and Tracking (SST) is the ability to detect and predict the movement of space debris in orbit around the Earth. SPOOK (SPace Object Observations and Kalman filtering) is a versatile and highly configurable software tool developed by Airbus DS GmbH, for the detection, cataloguing and orbit prediction analysis of Earth orbiting objects.

Multibistatic Radar for Space Surveillance and Tracking

IEEE Aerospace and Electronic Systems Magazine, 2020
The ever increasingly resident space object density poses a challenge for current and future space missions and assets. Space debris in low Earth orbit (LEO) are of particular interest because they are present in the highest concentration with respect to the other orbits.

Metrological Characterization of Ground-based Sensors for Space Surveillance and Tracking

2021 IEEE 8th International Workshop on Metrology for AeroSpace (MetroAeroSpace), 2021
In many Space Surveillance and Tracking (SST) operations, from the cataloguing of trackable space objects to orbit determination and correlation, ground-based measurements play a central role. In this frame, the monitoring and, if necessary, the update of the sensors' calibration parameters is of utmost importance to correctly evaluate the positions of

The Missile Defense Agency's space tracking and surveillance system

Proceedings of SPIE, 2008
The Ballistic Missile Defense System (BMDS) is a layered system incorporating elements in space. In addition to missile warning systems at geosynchronous altitudes, an operational BMDS will include a low Earth orbit (LEO) system-the Space Tracking and Surveillance System (STSS). It will use infrared sensing technologies synergistically with the Space
