How to open IMU and GPS data from previous flights in robot_localization ROS2?

How to open imu and gps data from previous flights in robotlocalization package ROS2? I have an IMU data from VN200, gps data from HERE3. I want to pass data through robotlocalization Kalman filter.

My goal is to compare data from robot_localization Kalman filter and from VN200 built-in EKF. I think that a visual method of comparison would be to plot graphs via plotjuggler. Please provide a step by step guide if its possible, I`m a newbie in robotics ros2.

Are you familiar with recording and playing back data?

I think there's enough information available on wikis for you to figure out what needs to be done. ROS 2 and robot_localization are well documented; I recommend putting in the legwork to learn how to launch nodes and use recorded data.
