Veronte HIL & SIL Simulators

The ability to test and simulate UAV and eVTOL systems is essential for the development of aerial platforms. Flight simulations allow mission-critical systems and configurations to be verified and checked. Two tools are available; our team will help to determine the appropriate tool for your application.

Veronte Hill UAV Simulator

HIL (Hardware-in-the-Loop) SIMULATOR – hardware simulates specific environments and situations, and monitors the autopilot. Real-time responses of onboard hardware are taken into account.

SIL (Software-in-the-Loop) SIMULATOR – software simulates the operation of the drone or eVTOL, without the need for real hardware. The software system can be programmed to simulate and control the flight (start, restart, etc.) and records detailed analysis of the system’s navigation and control algorithms, which are not available using the HIL Simulator. The SIL Simulator can connect with Veronte PIPE software.
