The Impact of Arm-Lever Effect Error Based Large Initial Misalignment Transfer Alignment Technology Study
TL;DR: In this paper, an initial misalignment angle transfer alignment model of AINS was established, which is other than traditional velocity and attitude matching algorithm. But the model is specific to rigidity carrier ship, and it deduces the model equations of Airborne Inertial Navigation System's velocity and acceleration with the effect of arm-lever vector.
