چکیده
Abstract Aiming at the problem of rapid transfer alignment inertial navigation system in shipborne environment with large azimuth misalignment angle, a dimension reduction fast scheme aircraft based on CKF algorithm is designed. Firstly, nonlinear attitude error equation, velocity equation and position Global Navigation Satellite System (GNSS) assisted strapdown case are analyzed. Secondly, dimensionality state measurement derived. Finally, simulated verified, compared EKF UKF algorithm. The simulation results show that reduced method can complete estimation angle 80s, horizontal 1’ 4’, accuracy equivalent to UKF, less calculation better rapidity.

Rapid Transfer Alignment of MEMS SINS Based on Adaptive Incremental Kalman Filter
In airborne MEMS SINS transfer alignment, the error of MEMS IMU is highly environment-dependent and the parameters of the system model are also uncertain, which may lead to large error and bad convergence of the Kalman filter. In order to solve this problem, an improved adaptive incremental Kalman filter (AIKF) algorithm is proposed. First, the model of SINS transfer alignment is defined based ...
متن کاملIntegration Scheme for SINS/GPS System Based on Vertical Channel Decomposition and In-Motion Alignment
Accurate alignment and vertical channel instability play an important role in the strap-down inertial navigation system (SINS), especially in the case that precise navigation has to be achieved over long periods of time. Due to poor initialization as well as the cumulative errors of low-cost inertial measurement units (IMUs), initial alignment is not sufficient to achieve required navigation ac...

As high dynamic movement is always accompanied by colored noise which lacks of mathematical model, traditional Kalman filtering based on an assumption of white Gaussian noise always faces serious divergence. To enhance the performance in high dynamic environment with uncertain colored noise, a kind of robust filtering based on H-infinity technology is developed. State model of the algorithm is ...
متن کاملAnalysis of alignment algorithms with mixed dimensions for dimensionality reduction
We consider an alignment algorithm for reconstructing global coordinates of a given data set from coordinates constructed for data points in small local neighborhoods through computing a spectral subspace of an alignment matrix. We show that, under certain conditions, the null space of the alignment matrix recovers global coordinates even when local point sets have different dimensions. This re...
