GaiaCode is the exclusive manufacturer of a revolutionary new line of multidisciplinary geophysical and seismic instrumentation designed by the world leading expert Dr. Cansun Güralp.

With 2.7 billion people now living in areas of dangerously high seismic activity, energy resources operating on ever finer margins and unprecedented developments in the dynamics of international security, the development and improved availability of accurate and scalable arrays has never been more important.

GaiaCode use modern best practices in material technology, electronics and networking to offer class leading solutions to these global problems.

Where it all began


At GaiaCode, our founder Dr Cansun Güralp, invented the first-ever Feedback Broadband sensor with the following features:

  • Vertical feedback broadband sensor module with 89 mm diameter
  • First feedback broadband sensor that used triangular spring with fine anchoring wire (patent number: {7909570 (19 March 1979)}, USA patent (4,280,206, July21-1981)
  • First feedback broadband sensor that used capacitive differential displacement transducer with electromagnetic force transducer
  • First feedback inherently digital broadband feedback seismometer patent: UK: (2,144287A 17 July 1984)
  • First borehole sensor with an 89 mm diameter
  • First broadband vertical modular sensor with an 80 mm diameter, for a borehole sensor casing of 89 mm diameter
  • First broadband feedback seismic sensor which had a frequency response extending from DC to 30 Hz

Since the design of the first feedback broadband sensor with the above technical features a fundamentally novel and innovative Broadband feedback sensor concept has been introduced based on triangular (C spring) used in elastic mode in a zero spring topology.

Our founder

Dr Cansun Güralp

Founded in 2019. GaiaCode marks Dr Güralp’s return to academic and industrial seismometer manufacturing, 40 years after he first revolutionised the industry with the world's first ever broadband miniature feedback instrument.

In 1978 he patented a mechanism that used a triangular leaf spring anchored to a rotational point. In combination with a sensor mass of less than 120 grams and a differential capacitive displacement transducer, this ushered in a new era of seismic instrumentation.

Dr Güralp is once again bringing a novel range of seismometers to the market, making best use of cutting edge material and electro-mechanical design to make further advances on behalf of seismology, science and society.
