Raw Telemetry and Orbit Data

Raw Telemetry Data in the Frame Format

Raw telemetry data of the past ISAS mission are released with documents (in Japanese) to describe their formats.

These data have been archved in the SIRIUS database at ISAS since 1970's. They are in the original telemetry frame format, so that users need to parse the data using the accompanying documents.
