2.3.2 spase://NASA/NumericalData/ACE/Ephemeris/Definitive/P1D ACE Definitive Orbit, Daily Values, in GSE and J2000 GCI Coordinates 2021-04-27T15:38:11Z ACE Definitive Orbit, in Geocentric Solar Ecliptic, GSE, and J2000 Geocentric Ecliptic, GCI, Coordinates. Data in GCI and RTN Coordinates are received Daily by the ACE Science Center, ASC, from the ACE Flight Dynamics Facility, FDF, at GSFC. ASC transforms the Data into the other Coordinate Systems. The Data are reported for the Beginning and End of each DSN Telemetry Pass, and also for the Beginning and End of each Spacecraft Maneuver during a DSN Pass. Because the Attitude and Orbit of the ACE Spacecraft change relatively slowly, the FDF does not provide the Data on finer Time Scales. E.C. Stone, Please acknowledge the Principal Investigator, E. C.

The Software and associated Database of SSCWeb together form a System to cast Geocentric Spacecraft Location Information into a Framework of Empirical Geophysical Regions and Mappings of Spacecraft Locations along Lines of the Earth's Magnetic Field. This Capability is one Key to Mission Science Planning, both Single Missions and Coordinated Observations of Multiple Spacecraft with Ground-Based Investigations, and to subsequent Multi-Mission Data Analysis. spase://VSPO/NumericalData/ACE/Ephemeris/Definitive/P1D spase://SMWG/Repository/NASA/GSFC/SPDF Online Open FTPS from SPDF (not with most browsers) ftps://spdf.gsfc.nasa.gov/pub/data/ace/orbit/level_2_cdaweb/def_or/ Access to Data in CDF Format via ftp from SPDF HTTPS from SPDF https://spdf.gsfc.nasa.gov/pub/data/ace/orbit/level_2_cdaweb/def_or/ Access to Data in CDF Format via http from SPDF CDAWeb https://cdaweb.gsfc.nasa.gov/cgi-bin/eval2.cgi?dataset=AC_OR_DEF&index=sp_phys AC_OR_DEF Access to ASCII, CDF, and plots via NASA/GSFC CDAWeb CDF None E.C.
