Mission Planner Sim

Hi Guys

I am trying to simulate a lost of GPS on the mission planner quadplane simulation.

I’ve got the message “bad GPS signal health” and also the “GPS:NO FIX”. But I can still follow the progression of the plane on the map.

So, is this a real life situation, where the IMU takes over and allow us to fly it back home or is this a limit on the simulator that won’t completely cut the GPS
