Modern seismology requires continuous recording of the earth’s movements, and the Gecko is always on and continuously recording 3 channels of data. Continuous data is stored onto a local SD card or telemetered to a remote computer via wireless modem. Processing of the data is handled by analysis computers, leaving the Gecko to be as power efficient as possible, using well under 1W of power, meaning you can record over a month using a car battery, or indefinitely with a small solar panel and battery.
The Gecko uses the latest 32-bit Analogue to Digital Converter (ADC) chips to maximise the range amplitudes that can be recorded – the ratio of the largest to the smallest recordable signal is a factor of almost 8 million to 1.
