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.
