Robot Model blinking with robot_localization package

edit

Hello!

It appears when I run my robot localization package with my ROS rover simulation, the RVIZ file shows my model flickering and not stable. Furthermore the /odometry/filtered doesn't seem to be visualized as my /odom topic seems to be.

I ran roswtf and got :

Found 2 error(s).

ERROR TF multiple authority contention:
 * node [/ekf_se] publishing transform [base_link] with parent [odom] already published by node [/gazebo]
 * node [/gazebo] publishing transform [base_link] with parent [odom] already published by node [/ekf_se]

I am confused as to how to resolve this discrepancy.

How do I stop gazebo from broadcasting the odom -> base_link transform? I believe gazebo is publishing the transform automatically so I'm unsure how to remap it if its not in my launch file.

Here is my launch file:

<launch>

  <!-- these are the arguments you can pass this launch file, for example paused:=true -->
  <arg name="paused" default="false"/>
  <arg name="use_sim_time" default="true"/>

        respawn="false" output="screen">
          <remap from="tf" to="gazebo_tf"/>
      </node>






 <!-- convert joint states to TF transforms for rviz, etc -->
  <node name="joint_state_publisher" pkg="joint_state_publisher"

</launch>

THanks!
