Abstract

The geomagnetic field is the earth's natural defense that protects us from the cosmic rays coming in the solar wind. These energetic particles can damage our technology such as communication satellites, electric networks, hydroelectric and GPS navigation systems, especially in the South Atlantic Anomaly (SAMA). This work presents the design and implementation of a low-cost geomagnetic station to monitor the earth's magnetic field variations and their correlations with space weather. The station uses Commercial Off-The-Shelf electronic devices such as a Raspberry pi, high-precision analog-digital converters, and triaxial fluxgate sensors. The hardware system and the software allow the logging sensor’s data automatically. Preliminary results allowed us to measure variations correlated with Brazil's geomagnetic station in Medianeira.
