Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology, these events are summarized under the concept of space weather. This creates variations in the Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. Due to these effects as well as the scientific interest in space and the growing space industry, the need to monitor space weather, the space environment and how Earth is affected by them increases.

The purpose of this project set by the host company the Swedish Institute of Space Physics (IRF) is to define and evaluate an autonomous system for measuring the local geomagnetic variations, with future hopes of creating a network of systems for space weather monitoring. The work was done by analysis and testing a fluxgate magnetometer that was placed near the location of IRF’s operating variometer station. Results showed that the tested magnetometer had less precision than the existing station but could within a certain frequency range provide good results of the local geomagnetic variations that may be of use for space weather.
