Fluxgate Magnetometer System for Underwater Exploration

This article introduces the usage of a fluxgate magnetometer sensor system with an underwater explorer robot which is developed for geoscientific data collection. This paper introduces the UNEXMIN project where this system was developed and UNEXUP project where it is further developed and upscaled. The paper introduces the robot platform and the instrumentation system, but it focuses on the magnetometer system, explains it’s operation and integration within the robot’s system. The main purpose of the magnetometer system and the performed tests are also described. The further development ideas are also introduced.
