A Portable Inertial Navigation System Calibration Module Based on Two Dimension Revolving Platform and Multiaspect Prismatic Body

This article is aimed at designing a portable inertial navigation system calibration module based on two dimension revolving platform and multiaspect prismatic body. It solves that how to utilize the miniaturized portable automatic controlled revolving platform and multiaspect prismatic body to calibrate the inertial navigation system. This technique is under the condition which is independent of northbound datum. This article emphatically introduced the inertia navigation system calibration module which owns high structure performance, the separate scene calibration method which is independent of northbound datum. The paper also developed the confirmation for measurement uncertainty and performance. The design suggested in this article has high universal property and degree of automation. It can substantially reduce the request for out-field condition and profession ability of the maintainer. It can also decrease the personnel’s workload and the calibration cost. The system and module can increase the calibration efficiency and be used in out-field calibration for sundry accuracy of inertial navigation system.
