The RadMap Telescope is a compact multi-purpose radiation detector developed to provide near-real-time monitoring of the radiation aboard crewed and uncrewed spacecraft. We operated a first prototype on the International Space Station (ISS) for an in-orbit demonstration of the instrument's capabilities. Its main sensor consists of a stack of scintillating-plastic fibers whose arrangement allows the three-dimensional tracking and identification of cosmic-ray nuclei by reconstruction of their energy-loss profiles. In this contribution, we give an overview of the current status of the track reconstruction. We describe our neural-network-based reconstruction methods and present the performance of the trained convolutional network on simulated detector data. We also discuss the progress of the analysis of real data gathered on the ISS and the applied preliminary tracking methods. Our work is funded by the German Research Foundation (DFG, project number 414049180) and under Germany's Excellence Strategy - EXC2094 - 390783311.
