Latest results in strapdown airborne gravimetry using an iMAR RQH unit

, 2016
This paper summarizes the results of four recent airborne gravity campaigns, carried out between October 2013 and October 2015. For the measurements, a strapdown inertial measurement unit, type iMAR RQH 1003, was used in combination with a geodetic two ...

Distributed Strapdown Inertial Navigation System Error and Inertial Sensory Bias Compensation

Majlesi Journal of Electrical Engineering
In this paper, error dynamic model of Strapdown inertial navigation system (SINS) is employed for error compensation of Strapdown algorithm. Perfect visual sensor data is fused with inertial sensors to produce deviation vectors as noisy measurement ...

Online Calibration of Strapdown Magnetometers

IFAC Proceedings Volumes, 2009
Abstract In this work, an online calibration algorithm for strapdown magnetometers is proposed. The proposed method is based on the observation that the magnetometer's measurements are on an ellipsoid manifold. The algorithm is attitude independent and makes use of Extended Kalman Filter.

A new strapdown attitude algorithm

Journal of Guidance, Control, and Dynamics, 1983
This paper develops the application to the strapdown attitude problem of the rotation vector concept, in which obtaining a solution for the rotation vector and updating the attitude quaternion are considered entirely separately. A new rotation vector algorithm is derived which takes three samples of gyro data per update, and offers greatly improved ...

HRG strapdown navigator

IEEE Symposium on Position Location and Navigation. A Decade of Excellence in the Navigation Sciences, 2002
A new technology gyro, the hemispherical resonator gyro (HRG), has been developed which is ideally suited to strapdown navigation systems. The instrument offers greater reliability than current sensors due to its inherent simplicity. A fault-tolerant navigation system has been developed as a technology testbed to exhibit the instrument's capabilities ...

Application of Improved SRCKF for Strapdown Seeker

Proceedings of the 2019 4th International Conference on Automation, Control and Robotics Engineering, 2019
Strapdown seeker cannot directly obtain the information on the line of sight (LOS) angle and angular rate required for missile guidance. To solve this problem, in this paper, the nonlinear state equation and observation equation of strapdown seeker LOS angular rate is established. Volume Kalman Filter (CKF) algorithm is used to estimate the LOS angular
