International scientific conference Meeting on Operational and Research Capabilities for Better Understanding Solar-Terrestrial Interactions
Published by: Scientific Society Isaac Newton

In this work, we present a newly established three -axial magnetoresistive vector magnetometer for monitoring the Earth's magnetic field. The magnetometer is designed and developed by a team from the Institute of Astronomy and National Astronomical Observat ory at the Bulgarian Academy of Sciences. This instrument provides the possibility of continuous monitoring and study of short -term changes (seconds) in the Earth's magnetic field. A dynamic database with open access is organized. This provides an addition al opportunity for research and analysis of long -term geomagnetic dynamic processes related to various phenomena, solar activity, and space weather. The magnetometer shows a measurement accuracy of less than 1nT on every axis in combination with automatic internal temperature stabilization of the sensor triad and most sensitive electronic components. Temperature accuracy is 0.003°C at sampling rate of one data measurement per second.
