INSTITUTET FÖR RYMDFYSIK
The large number of new satellites greatly increases the risk of collisions and requires careful mapping of space objects. The Institute of Space Physics (IRF) and EISCAT AB will develop signal analysis and experiments for three-dimensional measurements of meteoroids and space debris using the new research radar EISCAT_3D. Data processing for space objects will be developed in parallel with data processing for ionospheric physics and aurora observations. This project uniquely combines modeling and analysis of radar data.
EISCAT_3D is a radar system for space and atmospheric research that has been under construction in Northern Scandinavia since 2017. In this PhD project, technically advanced methods will be developed to enable three-dimensional measurements of space objects using EISCAT_3D. Once the radar system is fully constructed, EISCAT_3D will be able to determine orbits of space debris as small as just a few centimeters in size. Orbits for these space objects can be determined using a single measurement from EISCAT_3D’s three receiving stations.
IRF will closely collaborate with EISCAT AB to study:
Data processing for space objects is developed in parallel with data processing for ionospheric physics. This enables better data products for both observational methods. The project's goal is to significantly improve the capability for measuring and tracking space objects for the application of space situational awareness with EISCAT’s radar system. The developed methods will be documented in peer-reviewed publications and made accessible to the international research community.
The three project goals above allow you to conduct unique research studies of Earth's space debris environment and meteors.
Basic eligibility for admission to doctoral studies at Umeå University is granted to those who have completed a master's degree, or fulfilled course requirements of at least 240 higher education credits, of which at least 60 higher education credits must be at the advanced level, or have an equivalent foreign education or corresponding qualifications. To meet the requirement for special eligibility for doctoral studies in space physics, the applicant must have completed approved courses in the subject area of physics totaling at least 120 higher education credits. Those who have acquired comparable knowledge in other ways, within or outside the country, are also eligible. These requirements do not need to be met at the time of application, only at the time of admission. Additional requirements include fluency in English. More information about doctoral education at Umeå University can be found here.
We are looking for someone who wants to work in an intercultural and international environment and has a strong ability to work both independently and as part of a team. Working with radar data from space objects may require passing a security clearance.
You should have good programming skills (Python, C++, or equivalent). Experience in signal processing, inverse problems, and/or numerical calculations in areas related to the work is an advantage.
The doctoral student will be admitted to the Department of Physics at Umeå University and will be employed and placed at the Institute of Space Physics in Kiruna. As a PhD candidate, you will focus on your doctoral studies by conducting your own research under supervision and taking doctoral courses. The goal of a doctoral position is to obtain a PhD degree. The duration of employment is limited to the equivalent of four years of full-time work and is set to begin in January 2026 or by agreement.
We offer a workplace with flexible working hours, up to seven weeks of vacation per year, well-developed occupational health services with wellness activities, wellness grants, and access to a gym on site.
Equality, equal opportunities, and diversity are fundamental principles in our workplace. We work with integrated equality measures, meaning that equality aspects are considered in daily work and in all decision-making processes.
