Trajectory Optimisation for a Rail-based Ttrack Surveying System

Railway transportation is crucial to reducing greenhouse gas emissions and meeting increasing global demand for passenger and freight transport. To maintain a reliable, high-capacity railway infrastructure, regular and accurate maintenance is necessary. The recent development of a Rail-based Track<br/>Surveying System that can be mounted on any...

Estimating Wind Fields Using Physically Inspired Neural Networks With Aircraft Surveillance Data

Wind estimation plays an important role in many aspects of our world, both for nowcasting and forecasting. This is also true for aircraft flight routes; where wind field knowledge can contribute to flight planning and safety. Aircraft can relay flight information back to ground-based receivers, from which local wind measurements can be derived....

Sustainability and Circularity Challenges in Aerospace Engineering Education: for the sustainability transition

The aerospace industry and TU Delft have set stringent climate goals for themselves and with each passing year, these goals seem all the more implausible. While sustainability in the aerospace industry is envisioned as futuristic, circular, net-zero aircraft, the change rarely comes from the grassroots. Although these technological solutions are...

Filtering techniques for orbital debris conjunction analysis

The steadily growing amount of orbital debris increases the probability and amount of collisions between two objects in orbit about the Earth. These collisions in turn create even more debris, and it is therefore important to keep track of future conjunctions. The U.S. Space Surveillance Network (SSN) uses ground- and space-based sensors to...
