F3A - Baseline Testing Model

Goal: Establish the baseline for evaluation of the shape model degradation or improvement.

Test Set Up

Data: Shape model 3.7 and 3.8 images, both global and TAG sites. Perturbed SPICE kernels.

Start: Nolan Shape Model

Navigation Uncertainties: TBD (Due 24 July 2015)-- The uncertainties will be added to the SPK and CK as done for the component test: a constant arc for the spacecraft position, changed at every OD, and a random pointing error at every observation, unrelated to the previous observation's error. If provided, we will use expected performance rather than requirements for the baseline.

Image Error: We are not using significant error for the images during this phase. It will only include a shot noise and pedestal.

Lens Distortion: N/A For PolyCam and MapCam, we are not applying lens distortion.

Build: Build the shape model, saving several very specific models along the way:

• Appch1: Far Approach 1.5m GSD global, computed with 1.5m MAPLETS -- Q=256
• Appch2: Best Effort Approach, 75cm GSD global, computed with 75cm MAPLETS
• 75cm1: 75 cm Global: 75cm GSD global, computed with 35cm MAPLETS
• 35cm1: 35 cm Global: 35cm GSD of TAG Site 1 It will be computed with 2.5 cm MAPLETS. 100x100 meters
