Possibilities of further improvement of 1-second fluxgate variometers
Andriy Marusenkov Lviv Centre of Institute for Space Research, Lviv, 79060, Ukraine
Abstract. The paper discusses the possibility to improve temperature and noise characteristics of fluxgate variometers. The new fluxgate sensor with a Co-based amorphous ring core is described. This sensor is capable to improve the signal-noise ratio at the recording short-period geomagnetic variations. Besides the sensor performance, it is very important to create the high stability compensation field, which is canceling the main Earth magnetic field inside the magnetic cores. For this purpose the new digitally controlled current source with low noise level and high temperature stability is developed.

Short summary
The paper discusses the possibility to improve quality of geomagnetic variations monitoring at the ground observatories. The new fluxgate sensor as well as electronics with upgraded temperature and noise characteristics are described. It is supposed that the application of the discussed in the paper results and recommendations will allow creating an fluxgate magnetometer with outstanding level of parameters.
