A New Error Compensation Scheme for Ins Vertical Channel
نویسندگان
چکیده
Abstract: In the inertial navigation system, the altitude error diverges exponentially if external sensors do not compensate it. To suppress divergence of the error, non-inertial aiding sensors that provide vertical information are utilized. With these sensors, the wellknown baro-inertial damping loop or the well-known Kalman filter mechanization can be constituted to compensate the error of the vertical channel. In this paper, a new error compensation scheme for INS vertical channel is proposed, especially with a barometer and GPS by fusing the two well established methods. The performance of the proposed scheme is analyzed by computer simulation. Copyright © 2004 IFAC

Integration 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...

Rotation modulation is an effective method to enhance the accuracy of an inertial navigation system (INS) by modulating the gyroscope drifts and accelerometer bias errors into periodically varying components. The typical RINS drives the inertial measurement unit (IMU) rotation along the vertical axis and the horizontal sensors' errors are modulated, however, the azimuth angle error is closely r...
