摘要

The results of the development of a mock-up of a strapdown inertial navigation system based on a hemispherical resonance gyro (HRG)and pendulous silicon accelerometers have been presented. The system block-diagram has been described. Particular emphasis has been placed on the description of the mathematical model used for the HRG calibration, as well as on the problems of calibration. The HRG characteristics before and after calibration have been described. The results of testing the system located on a fixed base, as well as when selecting angular motion of the turn table, have been given. The projected measures to improve the HRG-based SINS accuracy have been presented.
