Atlas-C Rugged Digitizer is a high-performance, field-ready data acquisition system engineered for seismic monitoring, structural health monitoring (SHM), and environmental sensing in harsh environments. Built as a ruggedized version of the Atlas digitizer, it delivers exceptional durability, precision, and reliability for demanding applications.
Designed for portability and ease of use, Atlas-C supports 3, 6, or 9 differential input channels, making it ideal for integrating with a wide range of external sensors in remote or challenging field conditions.
Atlas-C is equipped with advanced 32-bit Delta-Sigma ADC technology, ensuring ultra-high-resolution data capture with synchronized channels. The system supports adjustable sampling rates up to 1000 samples per second (sps), providing detailed and accurate waveform recording.
A dual-zone memory architecture enables both continuous monitoring and event-triggered recording:
With 1TB storage capacity and a hot-swappable external card, Atlas-C guarantees continuous operation without data loss. The use of MiniSEED format ensures seamless compatibility with industry-standard seismic analysis tools.
Atlas-C features high-precision GNSS synchronization, maintaining accurate time alignment across multiple units. Its dual GNSS antenna system with automatic switching ensures reliable positioning and timing even in challenging environments.
Stay connected anywhere with Atlas-C’s flexible communication options:
The system supports SeedLink protocol, enabling real-time data streaming and compatibility with leading seismic platforms such as SeisComP, Earthworm, and Antelope.
Atlas-C includes a built-in uninterruptible power supply (UPS) for mission-critical operations:
Engineered for durability, Atlas-C is:
The Atlas-C digitizer combines rugged construction, high-resolution performance, advanced connectivity, and reliable power backup, making it the ideal solution for professionals requiring accurate, continuous, and dependable data acquisition in extreme environments.

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.
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.

Answer: Yes, ATLAS may do both tasks in parallel. For event-triggering, threshold exceedance instead of STA/LTA is recommended for accelerometers.
Answer: The telemetry works through SeedLINK protocol, which holds data in its ring buffer whose size is by default 1GB (expandable): it corresponds to some days of continuous recording. When the telemetry goes down, the client may request data from the last packet received before the break and then recovered all the missing data. This is automatically handled by the SeedLINK client. Whether the telemetry is up or down, the device always stores data in a separate folder and the telemetry (SeedLINK) server detects it, and copies data in its ring buffer, ready to be sent on request.
Answer: This could be done in two ways. For example, if the 2 or more ATLAS digitizers are in the same LAN segment, either ATLAS could reach the trigger status and trigger all the other units with a broadcast message. If they are installed in different LAN segments (for example there is a gateway in the middle), this won’t work and we should install an additional module on a Linux machine that catches the alarms from the devices and implements a trigger voting algorithm.
Answer: MiniSEED, just like the continuous recording. But if we install the QUAKELOGIC Event Watchdog software to the remote server, the trigger files may be sent automatically to a remote server and exported in ASCII format, or the server may extract the event data from the continuous recording and perform the export. For example, this would be the best way to interact with a LABVIEW application.
Answer: The ATLAS digitizer can communicate with the remote server (Linux Machine) through MQTT and SeedLINK. The Linux Machine takes care of storing all the continuous recordings from the ATLAS devices and receives the trigger data through MQTT or just extracts it from the continuous buffer. At this point, data is still available in MiniSEED. Once we have a time window for an event, we may export it in ASCII.
Answer: The ATLAS digitizer can be powered by a 12 V solar panel (>100 W). The system requires a solar panel, 12V backup battery and controller unit. QuakeLogic can provide all these auxiliary hardware including on-site installation.
