Autopilot 4x

The Autopilot 4x is a fully redundant flight control system designed for applications where failure is not an option. While the 1x model already sets a high standard with sensor redundancy and certified reliability, the 4x goes further with complete hardware redundancy, multiple processing cores, redundant power supplies, and an advanced arbitration system – ensuring there is no single point of failure.

🔐 Key Advantages over the 1x Model

• 3+1 Redundant Architecture – three internal cores plus an optional fourth external unit, enabling dissimilar redundancy or parallel operation.

• No Single Point of Failure – independent power inputs, redundant communication buses, and a dedicated arbiter board guarantee continuous operation even if one core or module fails.

• Arbiter & Built-In Tests (BIT) – advanced arbitration continuously monitors system health and ensures seamless handover between control units in case of malfunction.

🔧 Shared Features with the 1x Model

Like the 1x, the 4x integrates high-end GNSS with RTK, multiple IMUs, advanced GNC algorithms, compatibility with multirotor, fixed-wing, VTOL, UGV, and USV platforms, and full support for ADS-B or Remote ID modules.

🌍 When to Choose Autopilot 4x

The 4x is the solution for missions requiring the highest level of safety and certifiability:

• Urban air mobility and eVTOL transport

• BVLOS operations over populated areas

• Defense and government applications

• Critical cargo or passenger missions

With Autopilot 4x, operators gain the confidence of a fail-operational architecture designed to meet the strictest aviation requirements, making it the ideal choice for next-generation autonomous operations.
