Product Description
GD-02 Cesium Optical Pump Magnetometer Marine Magnetometer for Marine Resource Survey
Product Description
The GD-02 Towing Marine Cesium Optical Pump Magnetometer integrates high-resolution cesium pump technology into a cost-effective, compact system, ideal for conducting professional magnetic surveys in shallow or deep waters. It offers high sensitivity and sampling rates for total field measurements across all applications. The proven cesium pump sensor, housed in a robust and durable casing, is suitable for use on both small and large vessels. Utilizing our software with any computer enables the recording, display, and printing of position data from GPS receivers and magnetic data from the magnetometer.
Feature of GD-02 Cesium Optical Pump Magnetometer
• Two high-resolution, high-sensitivity cesium optical pump magnetometers mounted on a sturdy tow frame 1.5m apart.
• Acoustic altimeters and stabilizers mounted on the tow frame.
• Each magnetometer equipped with a high-precision depth sensor.
• Synchronization of magnetometers, altimeters, and depth sensors every 1ms.
• Sampling rate of the system is 10Hz.
• Other technical specifications match the standard.
• Integrated design on a tow frame for easy placement, no cable entanglement, and synchronized depth operation to overcome traditional magnetic gradient measurement challenges.
Application Field
• Land and marine mineral resource assessment
• Geological surveys for land and marine areas, including deep earth construction and geological mapping
• Marine engineering exploration for channels, ports, optical cable/cable positioning, wind power, etc.
• Archaeological exploration for underwater shipwrecks and ancient structures
• Deep-sea exploration for oil and gas
• Earth magnetic field surveys
• Anti-submarine detection
• Detection and positioning of unexploded bombs, mines, and floating mines in vital waterways
• Ocean magnetic array services
