Airborne measurements. Open methods.

Full-history prediction comparison

0/6 endpoint targets passed; 6/6 numerical checks passed. The long-history prediction method remains unqualified.

These are generated software cases. They test the prediction-bound method, not which physical model the aircraft measurements support. Passing requires both the numerical checks and useful ranges: at most 20 m north, 20 m east and 50 m in height. A wide range fails even if it contains the known answer.

Displayed widths are rounded for readability; the sealed results preserve their full precision. Rejected or incomplete cases remain in the table. The calculation reuses the saved training observations, constraints and baseline trajectory values and Jacobians. It changes neither the physical calibration limits nor the original shared-coordinate normalization.

The closed comparison records 6/6 completed outcomes and 6 reserved bounds over 3.70 wall hours. There are no new aircraft fits or baseline trajectory-oracle queries; the interval-bound source streams are recomputed.

The 53-stretch model comparisons are unchanged. Even a complete endpoint pass would leave whole-period coverage, numerical treatment and the aircraft observation-error model to be qualified before new withheld-position fits.
