Popis: In this paper, the measurements alignment of distributed inertial measurement units based on all-accelerometer is presented. These inertial measurement units, or nodes, relate to each other via an ideal sensor network. A prime master node is used as the alignment reference based on a certain messaging protocol. First, the master nodes are aligned with respect to the prime master node, then the slave nodes are aligned with respect to their respective master nodes as well as the prime master node. Among the various possibilities of interpreting the messages sent between nodes, the main approach utilizing a nonlinear recursive least squares technique is devised to facilitate the alignment process by which the Euler angles building the misalignment matrix are estimated at nodes levels. Also, this recursive method will be useful in estimating the flexure motion. Simulation results show the feasibility of this approach.
