(PGV), Peak Ground Displacement (PGD) and Response Spectrum (RSA) at various frequencies of the event. GMC can report these parameters, which are related to the strength of shaking, to a data centre where a synopsis (such as a shake map) for disaster management facilities can be generated in almost real time over the Internet. An event file is also recorded in the memory, which is sent out from the instrument and also securely accessible over the Internet.

The GMC is self-contained and is equipped with an uninterruptible power-supply, which provides, excluding options, more than 3 hours emergency operation without external power with internall battery and more than 24 hours with additional external battery. Since the battery and power management are critical components in applications, excessive care has been taken in the charger design and the GMC is released as the first unit that can warn of a faulty battery before it is detected by a lack of communication during an AC power loss.

The GMC uses an intelligent "Real Time Clock" (RTC) with self-learning temperature compensation at a fraction of power and thus cost of a TCXO. The RTC is able to synchronize with GPS or NTP (Network Time Protocol based on Internet UTC timing) to provide high timing accuracy.

The instrument can be locally connected to a laptop through its ports for configuration, testing or data retrieval. The internal memory cards can also be simply exchanged to retrieve the data. Several advanced communication options exist such as for connection over the Internet; it can utilize a list of servers where the communication is based on a simple but highly secure file exchange.

Wired or Wireless Interconnected Network option enables the use of several units together in a time and trigger synchronised manner; wireless using the Wi-Fi and Wi-Synch options.
