Rviz odometry display fixed frame [closed]

edit

Hello,

I'm trying to use rviz to display the odometry data I have recorded from a GPS. For this I run the gps_common node to get the odometry from the GPS data renaming the TF frame:

$ rosrun gps_common utm_odometry_node frame_id:=/world

This outputs a odometry message correctly (checked using rostopic echo /odom). Now I run rviz and set as global fixed frame /world and add an odometry display, then set it's property topic to /odom, after which I get the following status details:

Status: Error

Topic: OK Transform: Transform [sender=/utm_odometry_node] For frame [fcu]: Fixed Frame [/world] does not exist

fcu is the node from which the GPS data comes and it is parameters has listed the default reference frame as:

~ssdk/tf_ref_frame_id (str, default: world)

tf reference frame.

I hace tried to check the frames with:

$ rosrun tf tf_monitor
RESULTS: for all Frames

Frames:

All Broadcasters:

Which must mean it doesn't detect any frames.

Which frame should I set as a fixed frame for the odometry to be shown? Should a new tf be broadcasted for this?

Thanks,
