System requirements
Weatherproof:
Antarctica=>harsh environment
Customized water resistant case(IP67 and MIL810F rated, Explorer Cases)
Ruggedized mil rated connectors for cabling (Amphenol)
Aluminum supporting structure for interior of the case (RatRig)
Autonomous/low-power:
The stations are only summer operated: time lapse between field campaigns ~ at least 10 months;
account for several weeks without solar power due to meteorological conditions
Resistivity meter4POINTLIGHT_10 W in autonomous/monitoring mode, Switch boxes (Lippmann company)
Deep cycle gel battery (110Ah cold rated, roughly 6 months of operation without solar power, Victron)
Solar charge controller PWM 12V- 10A
Simple timer programmed to switch on/switch off the resistivity meter before/after each data acquisition instance (4xday, 6 hrs interval ; less power drain on the system)
Two-way satelite communication:
Remotely download data => Real time data visualization; Assessing if site visit is required
Remotely change the measurement frequency => Optimizing the measurement frequency for the desired target process/event; Adjusting power consumption to avoid data gaps
4point Data Link (Schwab Research Technology)
Low-cost:
To make international A-ERT network feasible in the global context
Current system configuration including the resistivity meter, switch box, water resistant case, supporting structure, battery and solar panels has a total cost of approximately 10- 20k Euros depending the number of electrodes.
