Soft and Hard Iron Compensation for the Compasses of an Operational Towed Hydrophone Array without Sensor Motion by a Helmholtz Coil
Abstract
:1. Introduction
2. Soft and Hard Iron Compensation Simulating Towed Hydrophone Array Motion
- (1)
- To generate a magnetic field sufficiently homogeneous inside a region. This region shall be large to contain the segment of the hydrophone array;
- (2)
- To be able to produce a uniform magnetic field in any direction;
- (3)
- To be reprogrammable through a PC since the field produced by the laboratory set-up depends upon the location;
- (4)
- To generate a magnetic induction comparable with the Earth’s magnetic flux density (i.e., about 50 μT or 500 mG).
3. Experimental Procedure
4. Discussion on the Artificially Generated Magnetic Field
5. Uncertainty Analysis
6. Conclusions
