What Guralp Systems does

Güralp Systems Ltd is a UK-based designer and manufacturer of broadband seismic monitoring instrumentation, founded in 1985 and headquartered at 3 Midas House, Calleva Park, Aldermaston, Reading. The company builds an integrated hardware-and-software stack spanning broadband seismometers (3T-120, 3ESPC, Certimus, Radian), force-balance accelerometers (Fortis, Fortimus), 24-bit digitisers (Minimus, Minimus+, Minimus Lite, Affinity), specialised ocean-bottom systems (Orcus, Aquarius), and proprietary software platforms including Güralp Discovery for network and state-of-health management, Güralp Data Centre for streaming and archival, and the MAGNA event detection module. Differentiating technical capabilities include 40ms ultra-low-latency data transmission via the GDI protocol, any-angle operation on the Certimus/Certimus line, and the world's first SMART submarine cable integration of seismic and environmental sensors into commercial telecommunications infrastructure.

The firm sells primarily to government agencies and research institutions operating national-scale seismic monitoring, earthquake early warning, tsunami warning, volcano monitoring, induced seismicity, and structural health programmes. Reference deployments include Indonesia's InaTEWS national network (139+ stations since 2021), Natural Resources Canada's EEW system (190 Fortimus instruments entering operation May 2024), the ATTAC Central American EEW project (72 Fortimus units across Nicaragua, Guatemala, El Salvador and Costa Rica), a Southeast Asia EEW upgrade combining 106 broadband seismometers, 64 borehole systems, 128 accelerometers and 169 digitisers, and an InSEA SMART cable demonstrator deployed in the Western Ionian Sea with INGV. Additional adjacent verticals include dam safety monitoring (37 dams in Puerto Rico with Genasys), carbon storage and geothermal microseismic monitoring, and academic field experiments (nBOSS in North Borneo, NAMASTE in Nepal).

Güralp operates a hybrid go-to-market combining direct enterprise sales for large national-scale projects with regional distributor coverage (RTsys for France, Asiamet for Southeast Asia) and specialist implementation partners (ESG Solutions in Canada, Global Marine for the InSEA cable jointing). Revenue is generated through hardware sales, custom turn-key engineering solutions, network installation and commissioning services, and recurring after-sales services covering firmware, training and maintenance. Pricing is quote-based and not publicly disclosed. The company is privately held, with no public funding, M&A, or subsidiary structure disclosed and a headcount of 51-100.

Core offering

Güralp Systems designs and manufactures broadband seismic monitoring systems for research, civil and industrial use. Its core product range includes broadband seismometers, force-balance accelerometers and 24-bit seismic digitisers, complemented by data management software (Discovery, MAGNA, GDC) and turn-key monitoring solutions. Instruments detect seismic activity from major earthquakes and volcanic eruptions down to microseismic signals from carbon injection and geothermal operations, and are deployed in challenging environments such as the ocean floor, arctic ice shelf and deep boreholes.

Product overview

Güralp Systems designs and manufactures a comprehensive portfolio of broadband seismic monitoring equipment for research, civil engineering, and industrial applications. The product range encompasses seismometers (weak-motion broadband instruments like the 3T-120, medium-motion instruments like Certis and Certimus), accelerometers (analogue Fortis and digital Fortimus), 24-bit digitisers (Minimus, Minimus+, Minimus Lite, Affinity), and complete data management solutions (Güralp Data Box with MAGNA event detection software). These products work as an integrated system: sensors detect ground motion, digitisers convert analogue signals to digital format, and proprietary software (Güralp Discovery) manages network configuration, data acquisition, quality assurance, and remote instrument management. The company also offers specialized ocean bottom systems (Orcus OBS, SMART cable solutions) and turn-key seismic monitoring stations for challenging environments including boreholes, seafloor, and extreme conditions.
