Simple GPS guided vehicle

I'm trying to familiarize myself with ROS by doing simple DIY projects with the hardware I have. The goal is try to get a mobile base to navigate a direct/straight path from point A to point B where Point A&B are marked GPS coordinates (waypoints?). The sensors I have are GPS/AHRS sensors. I looked into the tutorials for ROS navigation for a while before realizing that the stack needs sensor streams from LaserScans or PointClouds.

I dont have any range sensors, and at this point I'm not too worried about obstacle avoidance. I have the GPS/AHRS sensor working independently in ROS and I'm trying to merge this all together with my motor controller. Is there anyway I can use the navigation package without a laser/range sensor? Is there an alternative package that I use to do navigate a direct path from point A to point B? Or, can I somehow use the navigation package with a simple usbcam instead?

Hey Is there any link that you can share to connect bebop to GPS in ros and set waypoints

If you don't need obstacle avoidance you can use the navigation stack without a map and without a laser scanner (We've used the configuration based on the pr2_navigation_apps). You just need to remove the base_scan sources for the costmaps.

You may still need to use a localization package to provide the estimated position of the robot. We used the robot_localization package and it worked really well.

Hope it helps!

Can you give us a link to your source code for the launch files? Working out which topics need feeding in move_base from robot_localization.
