Research on Distributed Attitude System Based on MEMS Inertial Sensor Network

Abstract

Multiple sensors in distributed attitude systems can be installed in different parts of the carrier, providing more information and introducing errors. Compared with the traditional attitude system, the common error sources of distributed attitude system sensors are installation error and inner lever arm error. In order to improve this problem, the installation error and inertial lever errors of distributed attitude system are analyzed and modeled. Simulation results are given. The results show that the installation error and the inner lever arm error have a great influence on the accuracy, which must be paid attention to in the practical application.
