WebKalman Filter Localization is a ros2 package of Kalman Filter Based Localization in 3D using GNSS/IMU/Odometry(Visual Odometry/Lidar Odometry). node ekf_localization_node Webekf_localization_node and ukf_localization_node use a combination of the current ROS time for the node and the message timestamps to determine how far ahead to project the state estimate in time. It is therefore critically important (for distributed systems) that the clocks are synchronized.
