Hello, I encountered a problem when I fused GPS data using Navsat_transform_node in Robot_localization. Odom1 is Odometry/ GPS, the message data type for this topic is nav_MSgs /Odometry, but my GPS topic is/GPS /fix, The message data type is sensom_MSgs /NavSatFix, so when I run the fusion program, my terminal will display an error. Is Odometry/ GPS generated by conversion required? However, in robot_localization http://docs.ros.org/, I was prompted to input the GPS topic of Sensom_MSgs /NavSatFix. I didn't quite understand this step, and I hope to get your answer. Thank you.

Bug report

Client [/outdoor_waypoint_nav/ekf_se_map] wants topic /gps/fix to have datatype/md5sum [nav_msgs/Odometry/cd5e73d190d741a2f92e81eda573aca7], but our version has [sensor_msgs/NavSatFix/2d3a8cd499b9b4a0249fb98fd05cfa48]. Dropping connection.

Hi @miku54, the link you used doesn't show the tutorial you are referring to. Also it may seem minor but important can you pls update the correct topics displayed. For example nav_msgs/Odometry vs nav_MSgs/Odometry
