GEObit introduces GEOsix series high resolution 6 analogue seismic channels telemetry digitizer / recorders. The size of the instrument is only 168 X 106 X 68mm. The power consumption starts only from 0.8W for 6 channels. Available sampling rate is 100 to 500sps/6ch and optional lower sampling intervals are supported. Built-in GPS receiver combined with ultra-accurate DPLL unit providing time drift 10e-9 sec ensures timing stability even in the absence of GPS signal. NTP timing is also available.

The unit is very flexible and accepts several types of analogue front end units so any type of seismic sensor can be connected. Additionally, it provides eight extra-low resolution and rate analogue inputs for seismometer mass position monitoring, or any other environmental parameter monitoring.

Eight TTL command outputs are supported for seismometer control or for any other external device control. Typically the digitizer supports differential variable gain preamplifier. Our force-balance sensor front end is also supported, providing a wide-band response (10sec – 98Hz) and high sensitivity 1500V/m/s by connecting a C100 sensor. Acquisition parameters and operation modes can be set from the user – friendly web interface.

The unit 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 information. The unit supports advanced functionality, implemented from the combination of trusted open-source software components. Because of it’s 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 PC. The data are stored in mini-SEED format into the microSD card. 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, and it is logged to SeisNetWatch developed by ISTI.metry.
