Re: [ros-users] GPS measurements on PR2 Simulator in Gazebo

Hi Tina,
Could you provide a little more details about what you want to be able to
do with the GPS? Most GPS units are not well suited for odometry but are
good at localization. There's a draft proposal explaining common navigation
frames here http://www.ros.org/reps/rep-0105.html

There are also a bunch of tutorials on how to use the navigation stack at
http://www.ros.org/wiki/navigation/Tutorials
This one in particular you may find useful
http://www.ros.org/wiki/navigation/Tutorials/RobotSetup/Odom For setting
the pose amcl uses the initialpose topic. You can set it through rviz
