When the ideal three-axis fluxgate sensor measures magnetic field, its total field does not change with attitude of sensor. However, due to limitations existing manufacturing and processing technology, has errors, It may cause hundreds thousands nanometers measurement error, so for high-precision detection, analysis correction errors are great significance. Aiming at above problems, this topic ...
A magnetometer instrument, based on a proposal submitted to the Europa Orbiter Announcement of Opportunity, is described. The primary science aim of the instrument would be to characterize the electromagnetic fields which are induced around Europa, Ganymede and Callisto. These signatures will then be interpreted in light of the internal structure of the moons. The design of the instrument consi...
Micro-fluxgate sensor with symmetrical core on both sides of the planar rectangular excitation and pick-up coils has substantially improved parameters compared to its single-core predecessor. Almost closed magnetic path for the excitation field allows much deeper saturation of the sensor core, which reduces the perming effect, hysteresis and noise. Perming of max. 5 μT for 6 mT field shock, 28 ...
Recent advances in the research of autonomous vehicles have showed a vast range of applications, such as exploration, surveillance and environmental monitoring. Considering the mining industry, it is possible to use such vehicles in the prospection of minerals of commercial interest beneath the ground. However, tasks such as geophysical surveys are highly dependent on specific sensors, which mo...
