| ABSTRACT: In this paper, two proposed computational methods of coarse alignment for strap down inertial navigation systems (SDINS) are presented. Their associated drift, skew, and scale alignment errors are evaluated analytically. Although the computational formulas for analytic ground alignment are identical in the ideal case, the error characteristics are dependent upon the employed basis. With properly selecting the basis to compute the best estimate of transformation matrix, the drift misalignment angles of analytic alignment can be made to be equivalent to those, which can be found by physical gyro-compassing. | ||||
