Outstanding and Uniqueª: GMS

Approval and Compatibility:

-  USGS tested and approved scientific and technical quality, used in NetQuakes system.

-  Possibility to integrate into the USGS (after agreement with USGS) NetQuakes program.

-  Swiss Precision and Quality.

Mechanical and Operational:

-  Small, robust cast aluminium housing.

-  Several internal sensor options.

-  Robust separate baseplate for easy installation and removal.

-  Lockable housing lid against unauthorized access or theft.

-  Tamperproof electronic compartment with dedicated cover.

-  Separate battery compartment to enable easy/fool proof access for non-technical people.

-  External visual LED indicators showing the status of operation as well as errors and warnings.

-  Intelligent battery management preventing damage to battery.

-  Intelligent “Real Time Clock” (RTC) with self-learning temperature compensation.

Triggering and Recording:

-  Independent sampling rates on each channel.

-  Continuous recording with ringbuffer.

-  Ability to create an event from any time within the ringbuffer data.

-  Several independent triggers sets from independent sources can be configured.

-  Fully configurable voting logic for the independent triggers.

-  Fully configurable trigger filters for each trigger independently.

-  Virtual channels with online processing: Vector sum, Filter, Decimate, Integrate, Peak/Average detection.

-  The recorded channels can be different from the monitored channels depending on the trigger algorithm.

-  Possibility to have common triggering over LAN.

-  Up to 32 GByte of storage on removable Compact Flash Card is supported.

-  User defined policy for data storage management.

-  Advanced admin and data server software.

-  Possibility to have more than one output stream.

-  Internal signal simulator.

-  Periodical state of health.

-  Communication to all deployed instruments without fixed IP's.

-  Auto detection of all the instruments in the LAN by the server software.

-  Can send short notice with peak ground motion parameters just after a trigger.

-  Recovery server configurable by user in case main configuration is lost.

-  Post processing algorithms available for realtime calculations.

-  Easy interface to user developed software as all operational commands are based on ASCII files.

-  Complete network security, no access from the outside as all communications are initiated by the unit.

Highly customisable options:

-  18 or 24 Bit, up to 6 channels.

-  Internal alarm relays module.

-  Internal analog modem module.

-  GPRS modem for data communication or SMS alarm on an event.

-  Interconnection over cable (time and trigger synchronisation).

-  Wireless time synchronisation with dedicated wireless channel 433 MHz.

-  Completely cable-free operation§ (no cables for power, communication, time / trigger synchronisation, etc).

-  GPS antenna for high precision time synchronisation.
