Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to a high-precision cesium optical pump dynamic magnetic measurement system applied to ship-borne hard links in shallow waters. Background technique [0002] The magnetic field that exists around the earth is called the geomagnetic field. Marine geomagnetic field measurement is usually a process of geomagnetic measurement carried out by ships carrying magnetometers while navigating at sea. At present, most marine magnetic field measurements can only be carried out by towing. The magnetic probe is towed in the seawater behind the survey ship, and the length of the towing cable is more than three times the length of the ship. This method of operation is easily restricted in some sea areas, such as offshore aquaculture areas, polar ice floes, etc., which will cause damage or even loss of the magnetic probe. In order to solve this problem, the patent No. 201520274872.7...
