I need some clarification.
What are the real differences between SITL and HITL other than using an actual Pixhawk to run PX4? Are there things I can do in HITL that are not possible using SITL? What can I accomplish with HITL that I can’t with SITL?
I have been using SITL to simulate autonomous missions using Python scripts. This involves manually entering GPS coordinates into a script. My goal is to get beyond software-only simulation and start using some real hardware to feed data to the sim. Is there some way to feed GPS parameters to SITL via MAVLink using external hardware?
Final question: I am using hexacopters. I notice that both jMAVSim and Gazebo have quadcoprters but not hex’s. Can I run HITL with my Pixhawk/PX4 set up as a hex?
Thanks for any light you can shed.
