Spacecraft Zenith Variations: Comparison of Results

Discussion

Minima

Figure ?? illustrates the minimum uncertainty and RMSs for each test, and at which iteration each minimum occurs. The following patterns are apparent:

• Test U achieves the minimum value for every 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).
