Abstract
PGS1 is a new compact portable seismic station, designed at INGV OBS and Earth Lab, that is specifically intended for the deployment of dense arrays of seismographs on-shore. With its low cost, compact design, high data-quality and long battery life, PGS1 is a perfect solution for seismic monitoring networks. PGS1 design is based on a solid polypropylene suitcase, containing a complete data acquisition system, two battery packs and a photovoltaic panel. The new Earth Lab 5s medium-period seismic sensor is included. The whole system meets the IP67 standard requirements both in transport and in acquisition configuration. PGS1 is normally equipped with one battery pack, one more pack can be added inside the suitcase achieving 40 days of battery life. The station is equipped with a photovoltaic panel, useful to extend the deployment length. Inside the suitcase, there are compartments where to store the seismic sensor, the photovoltaic panel and all the cables. Therefore, the station is very easy to transport.
Highlights
In the last three decades, the use of mobile digital seismic stations has become increasingly widespread both for active and passive seismological studies
The design of PGS1 is based on a solid polypropylene suitcase, Explorer Cases model 3818, and includes the new Earth Lab 5s medium period sensor, a recorder, one or two rechargeable Li-Ion battery packs, a photovoltaic panel, a battery charge regulator and other power supply circuits
PGS1 is equipped with SeismoLog, a geophysical recorder developed by the Ocean Bottom Seismometers (OBS) and Earth Lab, Istituto Nazionale di Geofisica e Vulcanologia (INGV)
Summary
In the last three decades, the use of mobile digital seismic stations has become increasingly widespread both for active and passive seismological studies. Compact design and high power efficiency, PGS1 is a perfect solution for building seismic monitoring networks It is intended for harsh natural or artificial environments, including zones damaged by earthquakes. The design of PGS1 is based on a solid polypropylene suitcase, Explorer Cases model 3818, and includes the new Earth Lab 5s medium period sensor, a recorder, one or two rechargeable Li-Ion battery packs, a photovoltaic panel, a battery charge regulator and other power supply circuits. This would mean walking to a distant place, while holding the station by its handle In this scenario, the suitcase would be in the so-called transport configuration, with the sensor, photovoltaic panel and cables stored inside, as shown in figure 2. The angle profile (8), constrained to the sensor compartment, holds the serial port connector, SD card slot, Ethernet connector, on/off switch and a set of four LEDs
