Magnetic Repeat Station Network on the Baltic Sea — Why So Needed?

Open access


The development of navigation systems requires more and more accurate base data. Currently, attention is paid to utilization of geophysical fields — gravitational and magnetic ones — for navigation purposes. The Earth’s magnetic field distribution — both onshore and offshore — is complicated and variable in time. Hence, it is essential to precisely know the secular variations in the area of interest. In the case of Baltic Sea, this involves establishing (re-establishing) of a marine network of secular points (repeat stations) and regular magnetic measurements of the three independent components of the Earth’s magnetic field. Such measurements require equipment that ensures not only high stability, but also information about sensors’ orientation in relation to geographic north and to the level. This article presents a new project of the Baltic network of repeat stations and gives a solution for the instruments usable for quasi-absolute magnetic measurements.
