Test F3G - Navigation Error
Goal: Identify a limit to how large the navigation error can be and still get a good solution. Also, see if small errors converge to the same state (i.e. that within certain boundaries, error is fully removed)
Test Set Up
Data: Approach, Preliminary Survey, and Detailed Survey PolyCam and MapCam Images:
- All NOMINALS and SUMFILES are perturbed as per F1A - Baseline.
- All perturbations are random, no systematic perturbation are included (i.e. there is no simulation of spacecraft position or pointing drift).
- Detailed Survey Images:
Equatorial Stations MapCam images at approx. 30cm and 20cm pixel resolution.
Baseball Diamond Nadir (10am and 2pm stations) PolyCam images at approx. 5cm pixel resolution.
Baseball Diamond Off-Nadir (10am station looking at 12pm, and 2pm station looking at 12pm) PolyCam images at approx. 5cm pixel resolution.
Start: 35cm Preliminary Shape Model and 150cm, 75cm, and 35cm global maplets
Build:
- Extended TAG Site 1 (50x50m) at 20cm, centered at -8.027, 262.768 (lat, wlong).
- Extended TAG Site 1 (50x50m) at 10cm, centered at -8.027, 262.768 (lat, wlong).
- Extended TAG Site 1 (50x50m) at 5cm, centered at -8.027, 262.768 (lat, wlong).
- Evaluate 20mx20m region centered on TAG Site 1, images TBD which are fully contained in the TAG site and fully cover a single 5cm maplet near the center of the TAG site.
Sub-Test F3G-1 to F3G- 7
- Run with 3x, 2x, 1.5x, 1x, 0.75x, 0.5x, 0.25x the baseline perturbation.
Only Detailed Survey PolyCam perturbations altered.
