Solar power system capacity calculation to provide 24 hrs power to seismic station (digitizer + sensors)

DOCUMENTATION
Wi-LAN LINK BETWEEN SEISMIC STATIONS

A wireless local area network (Wi-LAN) is a wireless network that links two or more stations to form a LAN.

DOCUMENTATION
BOREHOLE SENSOR CABLE AND CONNECTORS

Borehole sensor requires a marine-grade cable with water-tight connectors that can carry the weight of the sensor during installation.

DOCUMENTATION
CABINET DETAILS FOR SEISMIC STATIONS (AFAD)

Seismic stations require a cabinet to withstand exposure to weather without damage or loss of function.

DOCUMENTATION
HOW TO DETERMINE SEISMIC STATION AND BOREHOLE ARRAY LOCATION

The locations of seismic stations on the ground surface (so-called free-field stations) and geotechnical borehole arrays need to be determined carefully.
