The Space Environment and Radio Engineering Network (SERENE) at the University of Birmingham invites applications for a PhD position focused on exploring and understanding the complex environment of Very Low Earth Orbit (VLEO). As VLEO emerges as the next frontier for satellite operations, it holds significant importance for industry and governments alike. This research project aims to address critical challenges associated with satellite operations in this region, modelling it and understanding collision risks, end-of-life mission strategies, and the unique environmental conditions that satellites encounter. VLEO presents a range of unique challenges that differ markedly from those in traditional Low Earth Orbit (LEO). Satellites operating in VLEO experience increased atmospheric drag, exposure to atomic oxygen, and other phenomena that can affect their performance and longevity. The successful candidate will delve into these factors, investigating how they impact satellite design, operation, and sustainability. A key component of the research will involve assessing collision risks with space debris and other satellites, a concern that grows as more entities venture into this orbital region. The project will also focus on developing effective end-of-life strategies for satellites in VLEO. With the increasing number of satellites being launched, it's essential to establish sustainable practices to mitigate space debris and ensure the long-term viability of space activities. This includes exploring innovative disposal methods and ensuring compliance with international regulations. The research conducted will contribute to safer and more responsible use of space, benefiting both current and future satellite operations. As a member of SERENE, you will be part of a leading research group dedicated to advancing our understanding of the space environment and delivering practical solutions. Our work supports both civil and government operations not only in VLEO and LEO but also extends to studies in the ionosphere and radiation belts. You will have the opportunity to collaborate with experts in the field, access state-of-the-art facilities, and contribute to research that has significant global impact. We are seeking a highly motivated individual with a strong academic background in aerospace engineering, physics, space science, mathematics or a related discipline. Experience with computational modelling, data analysis, or simulation tools is desirable. The ideal candidate will have excellent problem-solving skills, the ability to work independently as well as within a team, and a keen interest in advancing space environment research and satellite technology. This PhD opportunity offers the chance to contribute meaningfully to a field of growing importance. As VLEO becomes increasingly vital to industry and governmental initiatives, your research will have the potential to influence the development of new technologies and strategies for satellite operations. Joining the University of Birmingham means becoming part of a prestigious institution known for excellence in research and education, where you can make a significant contribution to impactful research with global significance. The project will be supervised by Dr Sean Elvidge ( s.elvidgebham.ac.uk ). College of EPS funded post
