Spacecraft Zenith Variations
Test Over11 S/T/U Comparative Results
The measures of accuracy are plotted for each test in figures ?? to ?? under Tables and Figures (below).
Figure 1: Minima
Figure 1 illustrates the minimum uncertainty and RMSs for each test, and at which iteration each minimum occurs. The following patterns are apparent:
Test U achieves either the minimum value or within 0.03 cm of the minimum value for every RMS measure in the least number of iterations: 5 to 15 iterations sooner than Test T; and 15 to 20 iterations sooner than Test S (excluding Test S - CompMapVec RMS).
Test S consistently gives the largest RMS, with CompMapVec RMS showing no improvement from iterating.
- CompareOBJ RMS (with and without optimal translation and rotation varies across tests by less than 0.2cm.
- Residuals maintain a value of approx. 3.1cm through the first 13 iterations, then decrease through the remainder of the first 50 iterations, seemingly forming an asymptote at approximately 1.4cm after approximately 55 iterations.
