Looks like I didn't use the latest version locally.
I'll fix merge conflicts later

This looks great! Only thing left to do is add some documentation. After you resolve the conflicts I will test it 🚀

Should all services be moved to fsds_msgs?

as Reset.srv was moved while the SetGPSPosition.srv and SetLocalPosition.srv definitions are still in fsds_ros_bridge

Should all services be moved to fsds_msgs?

Yes! I think that would be the right way forward.

Tested it, works great!

I added a commit that removes the vehicle_name from SetLocalPosition.srv as FSDS only supports a single vehicle anyway. I also added the service file to the CMakeLists.txt because without it compilation failed.

Last thing to do is add a note in the docs. Let's also mention explicitly that setting the local position does not reset the velocity and also does not reset the command_controll.

Sorry, I didn't really have a lot of time in the past days.

Yes! I think that would be the right way forward.

Do you want this to be done in this PR? Or in another PR after this one.

[SijmenHuizenga]

@MarvinKlemp We can do it in a separate pr 😄

After you add some docs I we can merge 🚀
