Truth signal
true drift 1.00 NM/hr
Schuler amplitude 1000 m
Schuler phase 30°
noise σ 10 m
Test design
test window 85.0 min
total run length 200 min

The slope of the simulated horizontal error is fit using only the first test window minutes of data; the resulting line is then extended across the full run for visual comparison. Slide the window to see how the slope estimate moves relative to truth.
