GEO3tiny is a compact miniature seismic digitizer which integrates three seismic and three acceleration channels plus three extra analog channels for seismometer mass monitoring. It supports high resolution 24bit digitizer, embedded linux OS and GPS or NTP timing. Seedlink and Earthworm server ensures reliable real time data telemetry while large storage volume ensures long period local data recording. The instrument has extremely low power consumption so it can operate getting powered from a small 12Vdc battery. Due to its small size provides the ability to be buried underground. The analog input supports differential architecture and variable gain set, user configurable. Three extra analog channels can monitor seismometer’s mass position and three control lines can be used for seismometer Lock, Unlock and Centering. The digitizer can be connected to any kind of active or passive seismometer. It operates in continuous mode, triggered mode or both and data are streamed through different data ports. Local data storage is selectable as well as logfile in- formation. The unit supports advanced functionality, implemented from the combination of trusted open source soft- ware components. Because of its open-source architecture is able to run any custom application thus providing the next day solution to the user. The hardware is based over an embedded ARM9 400MHz ARM linux board running 14.6 linux kernel. The data are stored in mini-SEED format into the microSD card or to a removable USB stick. The instrument supports 10/100 ethernet port and debug port. FTP, SFTP, SSH are also available. The state of health is transmitted over UDP packets upon request.
