A series of high-sensitive and stable ring-core magnetometers have been developed to install on MS-T5,the first Japanese spacecraft to the interplanetary space. During the course of the development, we invented a new kind of magnetometer that consists of a high-sensitive and stable ring-core magnetometer and a time-derivative circuit. The six components of geomagnetic variations, H, D, Z, H, D, and Z can simultaneously be recorded by the magnetometer. Since it is the new magneto-METER to observe ULF waves with the Ring-core sensor, it is named RULFMETER. Both of the volume and weight of the rulfmeter sensor are only ∿1/25 of the total volume and weight of the previous fluxgate and induction sensors. Under the Circum Northern Pacific ULF Study Project, ULF waves were successfully and simultaneously recorded by rulfmeters at College, Alaska, San Gabriel Canyon, Los Angeles, Ewa, Hawaii, and Onagwa, Japan.
