ISEE 3 Daily Trajectory Data

This data set contains orbital parameters for ISEE-3: heliospheric radial distance in AU, solar ecliptical latitude, solar ecliptical longitude, solar heliographic latitude, solar heliographic longitude, and solar solar heliographic inertial longitude with respect to the ascending node of solar equator on the ecliptic. These data were obtained from running the program HELICOOR in the public directory NSSDCA::ANON_DIR:[ACTIVE.HELIO].

These data are based on predicted trajectories calculated with the GTDS code by the NSSDC Satellite Situation Center and converted to solar ecliptic and heliographic coordinates by the HELIOCOOR program. The HELICOOR code was written by R. Parthasarathy. The program GENTRJCON added the HILLON longitude.
