KRONOS M4D

    Conversion Kit for C2/C5

    The result of more than 10 years of research and innovation, the Kronos M4D system for the DJI Matrice 4D is designed to provide professional drone operators with a safety solution that is fast to deploy, easy to reuse thanks to the POD system, and fully compliant with the latest EASA standards (C5 / MOC M2 / MOC 2511). The Kronos M4D Parachute Recovery System uses a preloaded spring ejection mechanism to ensure fast, reliable, and repeatable parachute deployment.

    Kronos Parachute Recovery Systems integrate an autonomous deployment technology designed to minimize activation time and maximize safety in the event of a critical in-flight situation. The parachute is automatically deployed in less than 0.27 seconds, compared with approximately 3 seconds for manual activation.

    This ultra-fast response helps reduce impact energy, protect the drone and people on the ground, and allows operators to remain fully focused on their flight missions, knowing that a reliable safety system is continuously monitoring the drone.

    Features

    Below, you will find the main features of the product.

    Clip, Lock & Fly

    Dronavia's POD system, integrated into Kronos Parachute Recovery Systems, has been field-proven for over three years. For Kronos M4D systems, the operator just disconnects the POD from its USB-C connector and connects a new one — no unscrewing required, ready again in minutes.

    Engineered to Minimize Impact

    With the Kronos M4D Parachute Recovery System (PRS), a drone falling from 27.9 meters impacts the ground with less than 22.1 joules of energy. Without any safety device, the same fall would result in approximately 599 joules of impact energy.

    Built to Perform in All Conditions

    Like the DJI Matrice 4D itself, Kronos safety accessories are fully waterproof and IP54-rated, ensuring reliable performance in demanding environmental conditions — from rain and dust to the humid, salt-laden air common in coastal and maritime operations.

    Fully Compatible with Dock 3 Operations

    The Kronos M4D is fully compatible with the DJI Dock 3 ecosystem, allowing storage, charging, and automatic deployment directly from the dock without compromising operational capability. Note that certain remote-control functionalities available through DJI FlightHub 2 are not currently supported with this configuration.

    Klick: Instant Safety Control

    The Klick remote trigger gives operators immediate, secure control over parachute deployment. Using an encrypted long-range LoRa wireless link, it enables reliable manual PRS activation at any time during flight, with continuous link monitoring, operator alerts, and LED status indicators for full situational awareness.

    Plug In. Power On.

    Dronavia PRS and Flight Termination Systems (FTS) are designed for plug-and-play installation, letting operators integrate advanced safety systems quickly, without modifying the drone. Powered directly by the drone, they operate with unlimited autonomy, eliminating the need for additional batteries or charging.
