Webposes, resulting in increased accuracy for the entire team. Recently, estimation algorithms such as the Extended Kalman Filter (EKF) [4], Maximum Likelihood Estimation (MLE) [5], and Particle Filters [6], have been used to solve the CL problem. In most cases, however, these algorithms require that all robot measurements are communicated to a WebGPS and IMU data must be combined. GPS and IMU data must be combined together appropriate to form one, more accurate odometry data. This is done in ROS with a …
