Study on SRUKF Applied in Initial Alignment with Large Misalignment Angle on Stationary Base of SINS

Advanced Materials Research, 2011
The initial alignment error model of SINS (Strap-down Inertial Navigation System) with large misalignment angle is nonlinear. The traditional EKF (Extended Kalman Filter) was used to linearization a nonlinear system, but its performance is limited. In this paper we use the SRUKF (Square Root Unscented Kalman Filter) to process this nonlinear system and

Applied Quaternion Optimization Method in Transfer Alignment for Airborne AHRS Under Large Misalignment Angle

IEEE Transactions on Instrumentation and Measurement, 2016
The airborne attitude and heading reference system (AHRS) is an inertial system that provides the aircraft with navigation parameters in real time. A new coarse transfer alignment method is proposed for low-accuracy AHRS with a large misalignment angle between AHRS and master inertial navigation system (MINS). The new coarse alignment method is derived

Time-varying gyrocompass alignment for fiber-optic-gyro inertial navigation system with large misalignment angle

Optical Engineering, 2014
Abstract. Conventionalstrapdowngyrocompassalignmentmethodsarebasedontheassumptionthatthefiber-optic-gyro inertial navigation system has a small azimuth misalignment angle. A large azimuth misalignmentangle would lead to an extension of the alignment duration. A time-varying gyrocompass alignment methodto solve this problem is provided.

Fuzzy adaptive strong tracking scaled unscented Kalman filter for initial alignment of large misalignment angles

Review of Scientific Instruments, 2016
In the initial alignment process of strapdown inertial navigation system (SINS), large misalignment angles always bring nonlinear problem, which can usually be processed using the scaled unscented Kalman filter (SUKF). In this paper, the problem of large misalignment angles in SINS alignment is further investigated, and the strong tracking scaled ...
