Marine Magnetics - Model Sentinel2 -Stationary Magnetometer
The Sentinel2 represents a precision tool engineered for enhancing magnetometric survey accuracy by mitigating background variations prevalent in atmospheric conditions. It is designed for ease of deployment, being compact and lightweight, thereby reducing setup time and complexity. Leveraging a stationary magnetometer approach, it compensates for both random and systematic deviations caused by weather patterns, such as magnetic storms, which can diminish data quality. This feature is critically important during adverse weather conditions, ensuring that surveys remain reliable and interpretable. The Sentinel2 is compatible with a range of support software, including BOB Survey Software, which further aids in data management and processing, making it adept for field operations requiring comprehensive magnetic surveying capabilities.
- Integrated GPS for precise automatic time synchronization to UTC time
- WiFi user interface through a smart device or computer; wireless data transfer
- Significantly higher internal storage capacity compared to Sentinel1 when used underwater
- Integrated folding tripod for quick & simple deployment
- Orange shell for visibility
- 30 hrs battery life (@ 1 sample/1s) or 40 hrs (@ 1 sample/5s) or 45 hrs (@ 1 sample/10s)
- Large storage capacity
- Integrated GPS receiver provides automatic time synchronization
- Easy set up, you don’t have to orient the sensor, it’s entirely omnidirectional
There’s no accounting for weather- and magnetic storms are no exception. Even on an average day, background variation caused by atmospheric activity can obscure survey data and make it harder to interpret. On a bad day, noisy atmospheric conditions can render your data totally unusable. Unless you use a second, stationary magnetometer to compensate for both random and systematic background variation, that is.
The new, smaller, lighter, and even easier to set up Sentinel2 helps you cancel out errors and delivers more accuracy.
