Geomagnetic observatories are currently facing requirements that cannot be easily implemented with most existing observatory datalogger systems. These include, amongst others, real-time data transmission even from remote locations, high sampling rates and digital filtering, and delivery of data according to the INTERMAGNET 1 Hz standard. We believe that these challenges can best be handled in a community effort, and present the current state of an open-source datalogger software. We run this software on a Raspberry Pi platform, but it can be easily adapted to any other POSIX-compatible platform. In our setup, the system is attached to a modern and reliable power supply that can be remotely controlled and monitored. As a whole, we believe that this system is a good basis to address current challenges regarding geomagnetic observatory data acquisition, and we encourage international participation in the further development, improvement, and usage. |
