The wide-field optical system so-called Auroral Large Imaging System 4D (ALIS_4D) was designed to support research on light phenomena in the upper atmosphere, such as northern lights. Due to its characteristics, such a system can monitor a large part of the sky with overlapping fields of view from different stations located in the far north of Scandinavia.

With this project, we aim to answer the following questions: Can we track space objects using the ALIS_4D system? How ALIS_4D can contribute to the monitoring of space debris? To answer these questions, we are developing a cluster of algorithms to identify space object traces and compute their orbits, even though the system is designed for auroral analyses. These conditions introduce complexities to the problem related to the filters and the aurora itself on the image.
