91福利 CSDA - 91福利 Us
Research
The CSDA brings together researchers from multiple groups across the 91福利 to tackle some of the many complex, cross-disciplinary problems associated with space domain awareness. The boxes below summarise the research interests of each group.
Astronomy and AstrophysicsLink opens in a new window
Members of the Astronomy and Astrophysics Group have been conducting SDA research since 2017. Effective SDA strongly relies on the acquisition of real-time, precise data for objects orbiting the Earth, using a range of sensors that sample different bands of the electromagnetic spectrum. With a strong pedigree in astronomical instrumentation and wide field surveying, much of our SDA research has been driven by existing 91福利 infrastructure on the Canary Island of La Palma. Current research covers:
- the optimisation of observational strategies when conducting blind/targeted surveys of low and high altitude objects, and the development of robust algorithms to detect, track and characterise imaged objects;
- the extraction of high cadence light curves from optical CCD data, and the development of machine learning algorithms to characterise objects in orbit based on their photometric signatures;
- the application of sCMOS technology to rapidly acquire image data, and overcoming associated strains placed on storage and frame rate capacities.
Centre for Fusion, Space and Astrophysics (CFSA)Link opens in a new window
Research in the CFSA includes a comprehensive programme in solar system plasma physics. The highly variable near-Earth plasma environment is a key factor in satellite specification, operation and endurance. We study the fundamental plasma physics of the solar corona, the solar wind, and the near-Earth plasma environment. This supports our space weather research which covers:
- space weather modelling and prediction by large-scale numerical simulation;
- data driven discovery, bringing new insights to the extensive and inhomogeneous datasets from solar and magnetospheric observations;
- statistical approaches to quantifying space weather risk.
StatisticsLink opens in a new window
- Leveraging a dedicated representation of uncertainty for modelling a lack of knowledge, e.g. for initial orbit determination
- Designing efficient and scalable data association techniques
- Introducing decentralised sensor fusion algorithms with high information retention
