```auto
roslaunch px4 mavros_posix_sitl.launch

```

follows 2 small error.  
One is Error [Converter.cc:151] Unable to convert from SDF version 1.7 to 1.6

 ![image](https://discuss.px4.io/uploads/default/original/2X/0/090672e378a20febbbd4b7e995f540235ca6ede8.png)

[https://answers.gazebosim.org//question/7691/unable-to-convert-from-sdf-version-15-to-14/](https://answers.gazebosim.org//question/7691/unable-to-convert-from-sdf-version-15-to-14/)

I solved it by editing sdf file version from 1.7 to 1.6

The other error is

```
[ERROR] [1674526819.464722103, 51.024000000]: TM : Time jump detected. Resetting time synchroniser.
