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
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).
- 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 expected error.
Test Procedures
Summary:
- Create a large BIGMAP at a resolution of 20cm with a width of 50m. Register all images to this larger TAG site. Once this is done, we run GEOMETRY, option 2 to update the position of the spacecraft.

Evaluate:
- Change in Spacecraft Position/Pointing - evaluate the observed-actual spacecraft position and pointing;
- Evaluate the accuracy a 20mx20m region centered on TAG Site 1.
