A Practical Ship SINS Attitude Algorithm

摘要

Existing Attitude Algorithms for SINS Strap-down Inertial Navigation System has analyzed the error caused by them, i.e., the outputs of the inertial component don't include any disturbance. But many SINS work in atrocious environment, and it's unavoidable that the outputs of the inertial component include disturbance. From the point of view of engineering utility, the forth order Ronge-Kutta algorithm and three samples rotation vector algorithm were analyzed and compared, and it's indicated that the forth order Ronge-Kutta is an algorithm valuable for engineering utility. The simulation was given under the condition with disturbance and without disturbance.
