My aim was to filter gps data for navigation and for that I used 2 instance of ekf_localization node .One node subscribe to imu data that has been published with frame_id :=odom and generates a nav_msgs/odometry msg topic “/odom” which is further used by navsat transform to publish filtered gps _data but there is no data published on the odom topic and hence no futher topic are being published.
Can you provide some more information related to your problem? Is it happening in an exercise of our course? Is this something you are trying on your own? If it’s something you are trying on your own, could you create a ROSject so that we can reproduce the error?
Ricardo told me this issue has already been solved by him, so I will consider it as solved.
