      What is the Initial Alignment and How Does it Improve the Device's Performance?

      Purpose: To understand how the initial alignment improves the performance of the INS.

      What is it?

      During the Initial Alignment time, the INS estimates biases of the gyroscopes by measuring the current condition it is in (which should be static). The device can use these estimated biases in the Kalman Filter to help the device recognize the difference between when the unit is moving and when the gyroscopes are drifting. As a result, the initial alignment helps to improve the INS dynamic accuracy.
