mavros global_position topic not publishing
Hi, I am having problem getting the message published in global_position.
I am using Ubuntu 14.04 Ros Indigo and recently just updated the firmware. I use a pixhawk and 3DR Iris in Hexacopter .
The code I type is
roslaunch mavros px4.launch '
The code displayed is
NODES / mavros (mavros/mavros_node)
auto-starting new master
process[master]: started with pid [3595]
ROS_MASTER_URI=http://localhost:11311
setting /run_id to ed737cc2-9f24-11e5-83d8-605718672f0f
process[rosout-1]: started with pid [3608]
started core service [/rosout]
process[mavros-2]: started with pid [3626]
[1449741666.239332817]: Plugin global_position loaded and initialized
After that I type in
rostopic list
The info displayed are

But when I type in rostopic echo /mavros/global_position/local there is nothing displaying out same go to other topic in global_position except for global_position/raw/fix and global_position/raw/gps_vel
which the code is shown below

May I know why is there still missing messages publishing in global_position where the Plugin global_position loaded and initialized has been successful?
