Test F3C - Quality of Observing Condition

Goal: SPC is highly dependent on the stereo angle and illumination conditions of the images. However, there has not been a systematic study to show how much those parameters affect the accuracy of the solution. We will test the accuracy by adding a few images with better stereo and photoclinometry angles.

This has been supported by Test 09 OrbitBUltra, Test 10 UltraFeatureF2 and T11 ReferencePeaks, tests conducted as part of the Calibration Test Phase.

Test Set Up

Data: Nominal Orbital B and extra images (Use OBOptimal w/ Error orbital the Requirements)

Start: 35cm Detailed Survey Shape model

Build:

• TAG Site #1
• Use the "quality diagrams" to see where to add images
• Supports Safety map, FDS and NFT

Sub-Test F3C: Include non-physical solar angles to show the improvement of photoclinometry

Evaluate:

• Accuracy
• Relative Accuracy

Sub-Test F3C-1 - Matched Pairs

Four images with observing conditions matched with the Sun position. Meets MRD-576.
