OCR Implementation

The table provides details about each OCR and the associated modifications to measurement parameter tables, timelines and mission scenarios. Whenever a final flight configuration is permanently changed, the resulting final flight version number is given in brackets (identical to the version numbering given in the header/footer of parameter and timeline tables).

OCRs specifying only test measurements, i.e. measurements where the instrument is set back to the current final flight configuration at the end of the test phase, do not show such version numbers for measurement parameter tables. Timelines list the corresponding set ID of the test timelines
