The ring-core magnetometer carried by Sakigake has successfully detected clear multiple crossings of the helio neutral sheet and the interplanetary magnetic field (IMF) variations. The installed magnetometer had been improved to measure the smaller IMF intensity of ∿5nT. In the design of the magnetometer system, high fidelity of the magnetometer on board the spacecraft had to be examined with respect to following five problems : (1) electrical exactitude of the basic magnetometer, (2) alignment stability of the triaxial sensor assembly, (3) residual magnetism of the spacecraft, (4) stability of the spacecraft oscillation, and (5) capacity of telemetering of scientific data., 資料番号: SA0166719000}, pages = {45--57}, title = {「さきがけ」搭載リングコア磁力計について}, volume = {15}, year = {1986} }
