Online self-calibration research of single-axis rotational inertial navigation system

•Analyze the key errors of single-axis rotational inertial navigation system.•Use horizontal accelerometer outputs and attitude errors to estimate errors.•Can get higher observability degrees of the key errors.•The navigation errors can be effectively suppressed by rotation modulation.•Whole process...
