Ph.D.-Candidate in the field of Satellite Geodesy
Open Position at the Astronomical Institute of the University of Bern
The group “Satellite Geodesy” of the Astronomical Institute of the University of Bern (AIUB) offers the position for a
The focus will be on the derivation of time-variable Earth’s gravity fields from ultra-precise inter-satellite ranging data of the Gravity Recovery And Climate Experiment (GRACE) mission and its successor mission GRACE Follow-On, scheduled for launch in early 2018.
Today the analysts are still challenged with the GRACE processing. Regular comparisons in the frame of the H2020 project European Gravity Service for Improved Emergency Management (EGSIEM) have revealed that solutions from different GRACE analysis centers are not always fully comparable and therefore difficult to be combined. This was found to be mainly related to the underlying heterogeneous stochastic modelling in the GRACE data processing.
The main focus of the Ph.D. position will be on the derivation of empirical noise models and the thorough investigation of their impact on the time-variable gravity field solutions derived from GRACE/GRACE-FO data. In addition the candidate is expected to support the GRACE-FO pro-cessing at AIUB as soon as data will become available.
The candidate is expected to have successfully completed the master thesis (diplo-ma/“Lizentiat”/Master) in astronomy, geodesy, physics, or a related topic. Experience in gravity field determination from satellite data is an advantage. Background in computer science (coding in Fortran90, C++, or perl) is not a requirement, but beneficial for working in this project. The candidate should speak and write English fluently.
The candidate should start working in Bern as soon as possible. The position is scheduled for three years. The salary follows the guidelines of the University of Bern.
Applications (including CV, university diploma copies, possible references) should be received as soon as possible but no later than November 17, 2017 at the following address:
Informal information may be obtained at the above address as well.
The University of Bern is an equal opportunity employer and encourages in particular women to apply for open positions.

PostDoc / Research Associate position
in the field of
Space Debris Research / Space Situational Awareness
The Optical Astronomy group of the Astronomical Institute of the University of Bern (AIUB) has a world-leading position in the domain of optical surveys and characterization of space debris. AIUB operates the Zimmerwald Observatory equipped with a 1-m multi-purpose astronomical telescope (ZIMLAT) and a small-aperture robotic survey telescope ZimSMART. AIUB partici-pates in several civilian space debris tracking networks such as the International Scientific Opti-cal Observation Network (ISON) and the DLR-AIUB network of small robotic telescopes SMARTnet. With its research focus on space debris, space surveillance, and space situational awareness (SSA), the group is deeply involved in various ESA-funded studies and performs space debris surveys with the ESA 1-m telescope at Tenerife on behalf of ESA.
The successful candidate will be responsible for the AIUB participation in ESA-funded studies on space debris, space surveillance and space situational awareness with major focus on opti-cal observations. He/she will be responsible for the preparation of the study proposal and for the project management. In addition he/she will be required to actively participate in the plan-ning, data acquisition and processing of space debris observations for the Zimmerwald Obser-vatory and for the ESA’s 1m telescope in Tenerife/Spain.
- Active work on ESA studies on space debris, space surveillance and space situational awareness
- Preparation and leading ESA studies, project management
- Software engineering, including architecture and algorithm design, coding, software integra-tion and tests
- Perform hands-on tests and experiments in Zimmerwald
- Assist in education of bachelor and master and PhD students
- University degree (PhD or master or equivalent) in astronomy, physics, mathematics, aero-space engineering, geodesy, or a similar discipline.
- Proven experience of working in project-driven environments.
- Demonstrated computer skills.
- Capability to work independently and timely, as well as in small and large (geographically distributed) teams, enjoying to participate actively in meetings of international teams and to present complex research matter concisely and appealingly (oral and written).
- Willingness to work occasionally according to astronomical constraints (nightshifts, week-ends).
- Fluent English
