| Abstract | The Ulysses magnetometer uses two sensors, one a Vector Helium Magnetometer (VHM), the other a Fluxgate Magnetometer (FGM). Onboard data processing yields measurements of the magnetic field vector with a time resolution up to 1 vector/second and a sensitivity of about 10 pT. |
| Description | High resolution samples at about one-second intervals of the interplanetary magnetic field. Field vector components are given in units of nanoteslas and in RTN coordinates, where R is the Sun-spacecraft axis, T is the cross product of the solar rotation axis and R, and N is the cross product of R and T. The field magnitudes in nT are averages of scalar magnitudes at higher time resolution. One minute and one day averages are also available. |

| Mission Description | The joint ESA-NASA Ulysses deep-space mission conducted the first-ever out-of-ecliptic study of the heliosphere - the region of space influenced by the Sun and its magnetic field. The European-built Ulysses spacecraft was launched by the space shuttle Discovery on the 6th of October 1990, and remained operative until the 30th of June 2009, covering almost a full 22-year solar magnetic cycle.
