Multi-Vehicle(zephyr and iris) ardupilot gazebo simulation: Going to different points in Gazebo simulation for the same 'lat lon alt'

[amirrezasadeqi]

Hello dear contributors of this repository

I want to simulate a zephyr fixed-wing and an iris copter in one gazebo simulation using the forked version of this repository, SwiftGust/ardupilot_gazebo repository.

So What I have done is, I have opened the zephyr demo world in gazebo and inserted an iris model into the environment and finally saved that file as another file. after that I run SITL simulation for both iris and zephyr in the same location through -L option in sim_vehicle.py command. So I can assume when I give a guided lat lon alt command with the same arguments to both drones, the drones move toward a same location in the gazebo simulation, but each of them goes to a different place.

I have also set the same location in the <spherical_coordinate> tag in the world file but it did not help.

Sincerely!
