# Simulation

Virtual Skynode allows simulating the entire Skynode system in software:

Physical Skynode hardware can also be configured to run a simulation stack. This is useful when real peripherals should be connected to Skynode during simulation:

Auterion Simulator provides the solution you need for developing vision-based algorithms that require a photorealistic training environment:

Hardware in the Loop (HITL) runs the simulation against a physical Skynode device:
