parent frame: lidar (Velodyne)
child frame: GPS-RTK (origin located at the center of the GPS receiver on the robot)

# This result is measured and computed directly from CAD models of the robot and the mounting board.
x, y, z = -0.220, 0.000, 0.153

# orientation is omitted since it is not meaningful; GPS-RTK only provides 3D positioning data, rather than full 6D poses, because it has only one receiver on the robot.
