A Novel EM Implementation for Initial Alignment of SINS Based on Particle Filter and Particle Swarm Optimization

For nonlinear systems in which the measurement noise parameters vary over time, adaptive nonlinear filters can be applied to precisely estimate the states of systems. The expectation maximization (EM) algorithm, which alternately takes an expectation- (E-) step and a maximization- (M-) step, has bee...
