More than one base_link transformation

edit

Hi, I integrated a positioning sensor onto my robot. The positioning sensor has its own two frames i.e. odom_frame which is the odom frame for sensor and jupiter_link which is the sensor frame. So, i wanted to compare the data of the odometry coming from encoders to the positioning sensor odometry data in base_link frame. The tf tree structure is something like this odom--->base_link--->positioning_sensor odom_frame--->jupiter_link

So, actually now there are two odom frame exits one from the sensor and the other from where the robot starts. Can i replicate base_link by naming base_link1 in the urdf so that i can get tree structure like this: odom_frame--->jupiter_link--->base_link1.
