Marine Magnetics System / Package
Synapse
Self-organizing networked magnetometer nodes with a 20 Hz optically pumped rubidium sensor, scalable from 1 to 30 nodes on a single topside cable.
Description
Synapse is a networked marine magnetometer system built from identical, interchangeable nodes. One node takes charge of the network, recognizes any sensor that is added and sends synchronized data topside over a single cable; Marine Magnetics says this can cut on-vessel setup from half a day to half an hour.
Key features
- 20 Hz optically pumped rubidium sensor (tuned Overhauser option listed as coming soon)
- Sensitivity 0.01 nT, resolution 0.001 nT, range 18,000-120,000 nT
- Neutrally buoyant nodes, 89 cm long, 3.5 kg in air
- Up to 30 nodes; 1000 m depth rating (H-Grad frame 300 m)
- Optional altimeter, tilt IMU and pressure sensor
- 4.5 W per node (7 W with altimeter and IMU); 24 VDC supply (9-30 VDC)
Applications
- Synapse: single node for AUV/ASV, ROV and side scan integration
- Synapse Array: up to 30 nodes for pre-construction hazard clearance
- Synapse H-Grad: horizontal gradiometer with a 1.5 m frame, under 23 kg with nodes
