Abstract EN
The performance of a strapdown inertial navigation system (SINS) largely depends on the accuracy and rapidness of the initial alignment.
The conventional alignment method with parameter identification has been already applied widely, but it needs to calculate the gyroscope drifts through two-position method; then the time of initial alignment is greatly prolonged.
For this issue, a novel self-alignment algorithm by parameter identification method under inertial frame for SINS is proposed in this paper.
Firstly, this coarse alignment method using the gravity in the inertial frame as a reference is discussed to overcome the limit of dynamic disturbance on a rocking base and fulfill the requirement for the fine alignment.
Secondly, the fine alignment method by parameter identification under inertial frame is formulated.
The theoretical analysis results show that the fine alignment model is fully self-aligned with no external reference information and the gyrodrifts can be estimated in real time.
The simulation results demonstrate that the proposed method can achieve rapid and highly accurate initial alignment for SINS.
