Analysis of Laser Gyro Strap-down Inertial Navigation System for its Self-Navigation and Integrated-Navigation Experiments in the Static State

Abstract

In this paper, the test for the laser gyro strap-down inertial navigation system is studied. The self-navigation and the integrated navigation are introduced. By comparing the measuring results with the real data, the accuracy for the integrated-navigation is obtained. The errors for the head, the roll and the pitch are 11.16″, 3.52″, 2.08″, for the location is 0.13m. In the same way, the accuracy for the self-navigation is obtained. The errors for the head, the roll and the pitch are 15.17″, 3.74″, 5.22″, for the location is 0.56m. As a result, we can find that the accuracy for the integrated navigation is better than the self-navigation, however they both agree well with the designing results.
