Abstract:

The principle of the nongyroscopic strapdown inertial navigation system is discussed. The mechanical calibration equations are formulated, and the methods to improve the accuracy of the calculation of the carrier’s angular velocity are proposed and analyzed. Then the configuration which is practical to the engineering application is obtained. The configuration is simulated on the computer, and the results are satisfying

Key words: navigation, inertial navigation, strapdown, nongyroscopic
