Abstract
Navigation in the Arctic region is strongly compromised due to extreme environmental conditions. Among the others, correct positioning is the most critical aspect to manage in such environmental conditions. The main criticality for this can be ascribed to the low-orbit of satellites used for positioning, which implies very weak signals received at ground. To overcome such limitations, this work aims to investigate and develop a solution that provides highly accurate positioning by monitoring and mitigating the ionospheric impact on GNSS signals. Improving quality of the received signals allows for safer routes for Arctic shipping. To this end, this study foresees the deployment of an ad-hoc regional wireless network, where each node is a GNSS station. This paper describes the technological choices made to guarantee the operation of the GNSS stations network in such harsh environments. Specifically, the paper focuses on the description of the low power communication and computing subsystems.
