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: 1 sigma of knowledge -- 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
  • 75cm: 75 cm Global: 75cm GSD global, computed with 35cm MAPLETS
  • 35cm: 35 cm Global: 35cm GSD of TAG Site 1 It will be computed with 2.5 cm MAPLETS. 100x100 meters
  • 20cm: 20 cm TAG Site 1, 60x60 meters, using all images available
  • 10cm: 10 cm TAG Site 1, 60x60 meters, using all images available
  • 5cm: 5 cm TAG Site 1, 60x60 meters, using only DS PolyCam images

Directory Setup

If needed to start

rsync --delete -hapvP ormacsrv1.lpl.arizona.edu:/Volumes/Data1/spc-test/F3A/ps/ ps

Make fresh and copy needed DS files over


cd F3A
ls ds          # should not exist
rsync -hapvP ps/ ds
rm ds/IMAGEFILES  # symbolic link
cp -av base/IMAGEFILES ds
cp -av setup/H2-DS-PolyCam-Nadir/perturbed-NOMINALS/* ds/NOMINALS
cp -av setup/H2-DS-PolyCam-Nadir/IMAGEFILES/* ds/IMAGEFILES
cp -av setup/H3-DS-PolyCam-Stereo-v5/perturbed-NOMINALS/* ds/NOMINALS
cp -av setup/H3Images/* ds/IMAGEFILES
/bin/cp -afv setup/registered-SUM/* ds/SUMFILES


cd base
cd scripts
ln -s XXX005.seed 0.00005.seed
ln -s XXX010.seed 0.00010.seed
ln -s XXX020.seed 0.00020.seed
cd ..

cd ds
ln -s ../setup/lsupport .

Get the images ready

cd ds
mv -f ../setup/new-PICTLIST.TXT PICTLIST.TXT 
rm support
ln -s ../base/support .

Register the images

We will register the images before starting the test. We are not testing either the routine register nor the operator's ability to use it. Thus, once they are registered, we will set them into the setup directory to be used when rerunning the whole thing.

  • Setup
mv -fv ../setup/registerImgList.txt make_script.in 
cp scripts/make_scriptR.seed .

Register the new images

imgListName=newImagesRegister.txt

Execute Block 3 - Register
