Working on: Visual navigation algorithms to allow cost-efficient exploration of small solar system objects, on-orbit servicing, and space debris removal. A notable project has been to develop the visual navigation system for the APEX CubeSat that is part of the HERA mission to the binary-asteroid 65803 Didymos. Three complementary algorithms were adapted/proposed to be fused with the main navigation filter. The algorithms were 1) a standard far-range absolute navigation method based on the target brightness centroid, 2) a medium-range absolute navigation algorithm developed by me and based on synthetic photometric landmarks, and 3) a medium- to close-range relative navigation algorithm based on DT-SLAM. Current interests include the implementation of the algorithms in suitable hardware, adjusting and testing them for on-orbit servicing and space debris removal use cases, and developing a deep learning-based absolute navigation method that can successfully handle a "lost-in-space" situation. An extended interest area spans e.g. 3D-printing, image sensors, and stellar photography.

Dr. Cyril Simon Wedlund
Cyril holds a PhD in Astrophysics from the University Joseph Fourier of Grenoble, France (2006). He is currently involved in the ESA Rosetta mission to comet 67P/C-G with emphasis on the interpretation of ion and plasma measurements from the RPC suite of instruments by use of global hybrid simulations. His interests range from the modelling of electron and proton precipitation of solar origin in the atmospheres of the Earth, Mars and Venus to the physico-chemical processes at the origin of airglow and aurora in the solar system, using space-born (Mars Express, Rosetta, Cluster, DMSP) and ground-based (EISCAT, ALIS) instrumentation. He loves photography, music, science fiction literature, aikido and archery.
Working on: Hybrid model development, Photochemistry/Ionosphere module, mass-loading, data analysis and interpretation, Comets, Mars.
