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.
TWINS-1 Ephemeris, Definitive Spacecraft Attitude, PT0.512S Data
Two Wide-angle Imaging Neutral-atom Spectrometers 1, TWINS 1, 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.
LP MOON SPACECRAFT EPHEMERIS V1.0
The Lunar Prospector ephemeris data set consists of spacecraft position and velocity determinations as a function of time in Moon-centered, Earth equator, mean of J2000 coordinates. Tracking data collected by ground stations are used by the Goddard Flight Dynamics Analysis Branch (FDAB) to compute the Lunar Prospector orbit ephemeris. The Level 0 Data archive contains the ephemeris type known as the 'definitive ephemeris', which is based on an updated lunar gravity model [FDAB1997].
ACE Electron Proton Alpha Monitor (EPAM) Ephemeris Data, 11.5 s Averages
12sec-averaged ephemeris data for the ACE spacecraft, Earth, and Jupiter. Also included are the orientation of the ACE spin-axis, and a rotation matrix for transforming from HEE cartisian coordinates to RTN coordinates.
THEMIS-B (P1/ARTEMIS-P1) Orbit (Ephemeris)
THEMIS-B Orbital Information provided via the Satellite Situation Center, SSCWeb, System and Services, Space Physics Data Facility, SPDF, GSFC, NASA
ACE Electron Proton Alpha Monitor (EPAM) Ephemeris Data, Hourly Averages
Hourly-averaged ephemeris data for the ACE spacecraft, Earth, and Jupiter. Also included are the orientation of the ACE spin-axis, and a rotation matrix for transforming from HEE cartisian coordinates to RTN coordinates.
VG1 JUP MAG/EPHEMERIS RESAMPLED SYS III (1965) 48.0SEC V1.1
Version 1.1 ----------- This version 1.1 data set replaces the version 1.0 data set (DATA_SET_ID = VG1-J-MAG-4-48.0SEC) previously archived with the PDS. Changes to this version include the addition of data columns not included in version 1.0, the modification of time format and flag values, and upgrade of associated labels and catalog templates to PDS version 3.2.
ACE Electron Proton Alpha Monitor (EPAM) Ephemeris Data, 5 min Averages
5min-averaged ephemeris data for the ACE spacecraft, Earth, and Jupiter. Also included are the orientation of the ACE spin-axis, and a rotation matrix for transforming from HEE cartisian coordinates to RTN coordinates.
