A multi-position self-calibration method for dual-axis rotational inertial navigation system

•A simplified installation error model of accelerometers is utilized in the self-calibration.•We represent the unknown initial misalignment by the inertial measurement unit errors based on their relationship.•We add a second order damper to the vertical velocity channel to suppress its divergence.•A...
