Gyroscopy and Navigation | Year: 2010
The results from the development of a mock-up of a strapdown inertial navigation system based on a hemispherical resonance gyro (HRG) and pendulous silicon accelerometers are presented. The system block diagram is described. Particular emphasis is placed on describing the mathematical model used for HRG calibration, and on the problems of calibration. The HRG characteristics before and after calibration are described. The results from testing the system mounted on a fixed base and with the selection of turntable angular motion are given. Projected measures to improve the HRG-based SINS accuracy are presented. © Pleiades Publishing, Ltd., 2010.
