We have a custom launch file.
To use it, add it to the catkin_ws/src/flightoggles/flightgoggles/launch directory
Then run it with the command roslaunch flightgoggles theAggregate.launch


on aws instance
export ROS_MASTER_URI=http://private_IP_of_AWS:11311
export ROS_IP=public_IP_of_AWS

on remote machine
  do hostname -I, the first input matters
export ROS_MASTER_URI=public_IP_of_AWS
export ROS_IP=output_of_hostname_-I
