STEREO Attitude and Orbit Data

STEREO atttitude and orbit data are distributed as SPICE kernels. Since most SEP investigators would rather not deal with SPICE kernels, Caltech provides these data in ASCII text format, as follows:

• text files containing transformation matrices for converting vectors from the Spacecraft coordinate system to the following coordinate systems: GEI, GSE, GSM, HCI, HEE, HEEQ, RTN.

• text files containing position data for the two STEREO spacecraft, in the following coordinate systems: GEI, GSE, GSM, HCI, HEE, HEEQ.
