MMS 4 Magnetic Ephemeris and Coordinates (MEC) and Support (Tsyganenko 1989 model, Dynamic conditions), Level 2 (L2), Burst Mode, 30 ms Data
Magnetospheric Multiscale 4 (MMS 4) spacecraft position, velocity, attitude, angular momentum vector, and magnetic ephemeris and coordinates (MEC), Level-2 science data at Burst (30 ms) time resolution. The Magnetic ephemeris data are calculated by using the Tsyganenko 1989 magnetic field model for disturbed magnetospheric conditions. Many variables are included in this data product including the magnetic field measured at the spacecraft. If possible, the northern and southern hemisphere footpoints of the spacecraft are found by tracing along the magnetic field line threading through the spacecraft per the given Tsyganenko and internal magnetic field models. The northern and southern hemisphere loss cone angles are also given. The magnetic field strength at the footpoints and the minimum magnetic field strength along the field line are also calculated by using the field models. Other variables list the spacecraft L-shell, the magnetic local time, the magnetic latitude and longitude, and whether the threading field line is open, closed, etc. Rotational quaternions are provided to allow coordinate transformation from GEI into 11 other coordinate systems including BSC, GEO, GSE, GSE2000, GSE, and SM. The list of ancillary variables includes the dipole tilt angle, the Dst and Kp actvity indices, and separate flags that denote satellite eclipse by the Earth and Moon.

TWINS-2 Ephemeris, Definitive Spacecraft Attitude, PT0.512S Data
Two Wide-angle Imaging Neutral-atom Spectrometers 2, TWINS 2, Spacecraft Attitude data, Earth Centered Inertial, ECI, coordinates. This TWINS data set contains spacecraft attitude data as polar and azimuthal instrument pointing vectors. The polar vector points along the TWINS rotation axis. The azimuthal vector lies in the plane normal to the polar vector and points toward the central scanning position, which is defined as the zero-point location. Such pointing is derived from both the spacecraft attitude history, SAH, file and the sensor mounting orientation. The computation employed is designed to achieve a pointing accuracy of 0.5°. Any deviation from this accuracy level is indicated in the header record metadata.
ULY JUPITER ENCOUNTER EPHEMERIS SYS3/ECL50 COORDS. VER. 1.0
This data set contains Ulysses ephemeris data near Jupiter covering the dates 1992-01-25 to 1992-02-18. Two slightly different versions of these data are included. The first (TRJ25_48.TAB), provided by the Ulysses MAG team (Imperial College/JPL), includes position data in Sys 3 spherical, ECL50 spherical, and ECL50 Cartesian coordinates. The Ulysses spin axis position is also provided in ECL50 spherical coordinates. The second version (SPK25_48.TAB), generated at the PDS/PPI node (UCLA), includes Sys 3 spherical trajectory, plus a spacecraft local time. Note that the position values for these two versions differ slightly. This variation is due to differences in the definitions of the Jovian physical constants used to generate them.
