A single unified interface to a range of powerful tools for managing your seismic network.

Instrument Management - Easily register and acquire real-time State-of-Health parameters from telemetered systems; remotely update digitiser firmware and upload configuration files to multiple units simultaneously.

Data Quality Assurance - Analyse seismic data for quality and verification purposes.

Event Data - Organise and view event data utilising Common Alert Protocol (CAP).

Güralp Data Centre - Record, forward and archive network data. Monitor network performance and latency.

Discovery is compatible with our Minimus digitisers and Minimus integrated sensors including Certimus, Fortimus and Aquarius.

 

Registering Your Instruments
IP address discovery and network connectivity are handled automatically by a registry server that operates ‘behind the scenes’ to register the presence and IP address of running instruments. This eliminates the requirement for static instrument IP addresses.



Monitoring State-of-Health
Discovery displays a range of key parameters indicating the instruments’ ‘health’, gathered and displayed in a simple list with a traffic light status for rapid assessment.

In the event of communication failure with an instrument, the system will alert the operator via text and email. This list can be logged over time if required.

State-of-Health information
> Host name and label
> System and product types
> Digitiser IP address
> Time since last contact
> Supply voltage
> System temperature, internal humidity
> GNSS status for time acquisition
> MicroSD cards recording status and available storage space
> Solar charge status/battery status when using Güralp Power Pack Modules

Rapid instrument Configuration
Instrument/digitiser configuration pages can be acccessed directly via an integrated PN/Tunnel that circumvents network address translations (NATs) present in internet modems and ADSL connections.

Operators can remotely update firmware and upload configuration files to multiple units simultaneously for rapid application to multiple systems.

A range of tools to analyse the performance of a seismic sensor.

Versatile waveform viewer

Choose to view live streamed data or loaded Miniseed files. Basic amplitude and time zoom functions with streams easily added or removed.
Signal statistics, measurements and comparisons can be performed with ease.



Power spectral density plots (PSDs)
PSDs of individual or groups of instruments forms the basis of a set of tools used to evaluate an
instruments performance as well as the quality of the installation.




Min PSDs
Analysis of instrument data over long periods of time can highlight intermittent faults or  installation shortcomings. The Min PSD function looks for the spread of noise recorded over time.



Instrument Response
New generation Güralp instruments and instruments connected via the Guralp Minimus digitiser have response (Poles/Zeros) and gain parameters recorded internally. This simple tool plots these parameters to verify their integrity.

Trigger events from instruments can be recorded and displayed on a map as part of a range of features dedicated to EEW implementations. This information is conveyed using the open Common Alert Protocol (CAP).

Map of triggered events from CAP receiver.
The information contained in the CAP message are displayed at the right-hand side of the window.



Event calendar view
Following an alert triggered by an event, you can view locally recorded data captured over the
preceding two weeks. Additionally, there is an option to back fill gaps in streamed data from the SD card.

Accessed and configured through Discovery, Guralp Data Centre offers a powerful range of tools for managing seismic network data and performance.

The Güralp Data Centre (GDC) is a cloud based data storage and management facility that offers simple and robust tools for managers of mission critical networks. Suitable for seismic networks of every scale, new instruments can be added easily and organised into groups or sub-networks based on any number of common features.

Networked instruments can be mass configured, using ‘virtual tunnel’, which creates a direct link between the instrument and the registry server. Data is streamed in industry standard SEEDlink to a central, typically cloud-based, server where the data is saved in configurable folder structures.

The GDC can be configured to simultaneously store, archive and forward data using the GDC ‘ringbuffer’, including to downstream processors such as Earthworm or SeisComP. For example, for Earthquake Early Warning applications, low-latency Causal data can be streamed to an Earthworm processor monitoring for EQ events, whilst Acausal data is saved to file for analysis at a later date.

GDC utilises industry standard protocols managed through a simple interface to ensure that the creation and operation of the seismic network is as simple as possible.
