Review of Calibration Method of Strapdown Inertial Navigation System
Abstract
Strapdown Inertial Navigation System (SINS) has been widely used in both civil and military fields, due to its low cost and flexibility. However, as a dead-reckoning method, SINS has an influential defect, which is the accumulation of error with time. In practice, the error can be significantly compensated by calibration. This paper focuses on calibration and aims to build the mathematical model of Inertial Measurement Unit (IMU). Through analyzing the two categories of calibration, this paper would note the new research direction in the future.
