Table A2.

Effect of speed on the cumulative distance versus gyro range. First (shaded) row reports the estimated slope of cumulative distance versus mean speed using the baseline sensor (2000 deg/s gyro). Remaining (unshaded) rows report estimated differences in this slope for IMUs with indicated angular velocity ranges compared to the baseline IMU (i.e., the increased error sensitivity to speed following the indicated reductions in angular velocity range relative to the baseline range).

Speed Effect	Estimated Slope (%/(m/s))	p-Value	95% Conf. Int.
Baseline (2000 deg/s)	−0.41	<0.01	(−0.68, −0.13)
1500 deg/s vs. Baseline	0.00	0.99	(−0.39, 0.39)
1000 deg/s vs. Baseline	0.05	0.81	(−0.34, 0.44)
750 deg/s vs. Baseline	−0.40	<0.05	(−0.80, −0.01)
500 deg/s vs. Baseline	−3.08	<0.001	(−3.47, −2.69)
