Atlas-C is a recorder for seismic signals.
It is available with 3, 6 or 9 synchronous channels for external inputs (accelerometers or velocimeters).
Atlas-C was designed to be used in the field in tough conditions without any additional protection.
An easy to access slot on the lid get the access to the additional removable microSD card and to the HSPA modem sim card.
WiFi, GNSS and HSPA antennas are built-in within the housing; should there be inadequate sky-view an external GNSS antenna connection is available with an auto-switch function.
Atlas-C features a high capacity battery pack for your daily surveys or as a back-up in case of power cuts.
Atlas-C is ready for use, no need to plug in antennas, no need for external battery back-up, no need for an external 3G modem, it is all built-in.
Atlas-C is an easy to use instrument that simplifies your work in the field.
Everything you need is built-in inside the housing: batteries, GNSS antenna, WiFi, HSPA.
If the Atlas-C has a good sky-view, the internal GNSS antenna functions perfectly; vice-versa, when it is necessary to plug the external GNSS antenna in, the system will auto-switch to the external one.
Data is simultaneously stored on the internal memory and on the external card.
You can eject the external card with your data and insert a empty one, without worrying about downloading.
Just bring the Atlas-C and your sensor, it’s everything you’ll need for your seismic surveys.
The Atlas-C power supply input can be directly connected to a small photovoltaic panel.
The overall power consumption of the station is maximum 12W when internal batteries are completly discharged.
The typical power consumption when the batteries are fully charged drops below 2W.
Permanent or short-termmonitoring
Atlas-C can be used with an accelerometric or a velocimetric sensor.
Atlas-C can be configured in-situ using WIFI or LAN cable.
If Atlas-C is used for permanent monitoring, it can be reached remotely using the built-in HSPA modem or using LAN connection in order to link it, for example, to an ADSL modem.
