Methodology

5. Compare to the corresponding Level-2 and/or Level-3 requirement.

The end-to-end requirements come from the Level-2 (SMRD) and Level-3 (LandIS) requirements, and the spacecraft/instrument/ground system contributors were collected from the LNext SOW (shown in red text) and from L8/L9 estimates of actual performance. The method used was:

1. For each end-to-end performance characteristic, determine which spacecraft/instrument/ground system contributors apply and how (e.g., once, once per band, once per scene).

2. Rescale the 3-sigma contributors to 90% linear error (LE90) or 90% circular error (CE90), as appropriate for the end-to-end requirement, and scale to ground meters based upon the LNext orbital geometry.

3. Include additional (usually small) allocations for terrain knowledge effects, ground control/registration accuracy, and algorithm/modeling error, as appropriate to the individual end-to-end requirement.

4. Roll-up the rescaled contributors, usually by root-sum-square but in a few instances (e.g., alignment stability) by summing, to calculate predicted end-to-end performance.
