ResourceID
spase://CNES/NumericalData/CDPP-Archive/ISEE1/Ephemeris/ISEE1_ORBIT_GSE

Description
ISEE 1 and 2 Orbit data description

Each ASCII file represents one day.
The coordinate system used is GSE (Geocentric Solar Ecliptic).
Data record are arranged chronologically.
One record each minute containing :
Time-tag, X.GSE (km), Y.GSE (km), Z.GSE (km), Vx.GSE (km/s), Vy.GSE (km/s), Vz.GSE (km/s)

Data in the records are separated by commas and blanks.
Caution: For the first line, the velocity is NaN (Not a Number) initialized.
