Voyager 1 Spacecraft Positions

ResourceID
spase://NASA/NumericalData/Voyager1/Ephemeris/P1D

Description

Voyager 1 spacecraft positions generated from data at HelioWeb (cohoweb.gsfc.nasa.gov/helios/heli.html) 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.
