Magnetometer system for studies of the equatorial electrojet and micropulsations in equatorial regions

Abstract

A magnetometer system for unmanned long-term observation in equatorial regions has been developed and is available. Because this system is designed for the study of both micropulsations and the equatorial electrojet, it must have accurate timing, high sensitivity, a wide measurement range, and a long-term recording capability. The equatorial regions we are interested in are quite remote far from sufficient technical and human support, and the breakdown of a public power supply is frequent. So, the system is requested to be compact and work successively in low power consumption with battery backup under equatorial environments. This system is successfully developed in low cost compared with commercial magnetometer system with similar properties.
