Several errors when using mavros.

edit

Hi,

I am using APM2.5 for localization. I configure the board on Mission Planar.

When rosrun, there are several warnings and errors. I mark them with bold and italic (three stars in code mode...).

I do not calibrate the RC, so the RC calibration error is reasonable. I also do not fix GPS, because I do not know how to do that in Mission Planar. It says that GPS will be fixed automatically when working outdoor. Is that the case?

Do anybody know the reason of other warning and errors?
