Design of INS/Image Sensor Integrated Navigation System (2008)
Oh, Seung-Jin, Kim, Woo-Hyun, Lee, Jang-Gyu, Lee, Hyung-Keun, Park, Chan-Gook
The errors of INS (Inertial Navigation System) are known to grow in time. To compensate the accumulated errors, measurements of external or onboard sensors are extensively utilized to form an...
Kim, Kwang-Jin, Yu, Myeong-Jong, Park, Young-Bum, Park, Chan-Gook
This paper deals with INS/GPS tightly coupled integration algorithms using extend Kalman filter (EKF) and unscented Kalman filter (UKF). In the tightly coupled approach, nonlinear pseudorange...
Park, Chan-Gook, Cho, Seong-Yun, Jin, Yong
In this paper, the error caused by the measurement delay in INS/GPS integrated systems with Kalman filtering is defined and analyzed through the analytical method and the simulation. It is proved...
A Leveling Algorithm for Strapdown Inertial Navigation System Using Extended Kalman Filter (2008)
Hong, Hyun-Su, Park, Chan-Gook, Han, Hyung-Seok, Lee, Jang-Gyu
This paper presents a new leveling algorithm that estimates the initial horizontal angles composed of roll angle and pitch angle for a moving or stationary vehicle. The system model of the EKF is...
Velocity Matching Algorithm Using Robust H$_2$Filter (2008)
Yang, Cheol-Kwan, Shim, Duk-Sun, Park, Chan-Gook
We study on the velocity matching algorithm for transfer alignment of inertial navigation system(INS) using a robust H$_2$ filter. We suggest an uncertainty model and a discrete robust H$_2$filter...
An Extended Kalman Filter Robust to Linearization Error (2008)
Hong, Hyun-Su, Lee, Jang-Gyu, Park, Chan-Gook
In this paper, a new-type Extended Kalman Filter (EKF) is proposed as a robust nonlinear filter for a stochastic nonlinear system. The original EKF is widely used for various nonlinear system...
Flexure Error Analysis of RLG based INS (2008)
Kim, Kwang-Jin, Yu, Myeong-Jong, Park, Chan-Gook
Any input acceleration that bends RLG dithering axis causes flexure error, which is a source of the noncommutative error that can not be compensated by simply using integrated gyro sensor output....
