Integrating a Parachute Recovery System (PRS) into a drone significantly enhances operational safety in the event of a technical failure or critical in-flight incident, such as extreme weather conditions, loss of radio communication, propulsion system malfunction, or GPS signal failure.

Parachute Recovery Systems (PRS) reduce impact forces and help minimize damage to both the drone and its surrounding environment during an emergency landing. They also play a crucial role in protecting people and property on the ground by mitigating risks associated with uncontrolled descents.

Dronavia Parachute Recovery Systems (PRS) enable a controlled emergency descent in the event of an in-flight issue by significantly reducing impact energy when the drone reaches the ground.

To achieve this, Kronos PRS feature an autonomous deployment system that automatically deploys the parachute in less than 0.27 seconds in the event of a critical failure. This is considerably faster than manual activation, which typically takes around 3 seconds, and helps ensure rapid response even when the operator cannot react in time.

Kronos PRS use the new PARA² parachute canopies, developed over ten years of research and testing. Their ultra-light design and advanced materials provide enhanced stability and efficiency, minimizing the descent rate relative to canopy surface area. The system is designed to keep the drone as level as possible during descent, helping to reduce potential damage on impact.

However, while the PRS is designed to optimize descent behavior, Dronavia cannot guarantee that the drone will remain perfectly flat during its fall. Descent behavior may vary depending on deployment conditions, such as altitude, weather, and ground characteristics.

Kronos Mini & Nano Parachute Recovery Systems (PRS) use a powerful pre-stressed spring deployment mechanism to eject the parachute canopy rapidly and reliably.

This deployment system has undergone extensive testing and continuous refinement, resulting in an exceptional level of reliability and consistent performance. The spring-based mechanism ensures fast, repeatable deployment, contributing to effective impact energy reduction during emergency situations.

For total safety, the Kronos Mini Parachute Recovery System (PRS) can also be deployed manually, using a Klick trigger remote control. The Kronos Nano Parachute Recovery System (PRS) cannot be activated by the Klick trigger remote control, but only by autonomous deployment technology.

Rearming the Kronos Parachute Recovery System (PRS) takes just a few minutes. Simply replace the old POD with a new one, then carry out a few simple maintenance operations yourself.

These operations are explained in detail in the PRS user manual and in tutorial videos available on our YouTube channel. You can either buy a new POD, or exchange your used POD for a new one at a preferential price.

There are two types of maintenance: preventive and post-deployment. In both cases, the only operation required on Kronos Parachute Recovery Systems (PRS) is replacement of the POD. This is a quick and easy operation, which means that the drone operator never has to immobilize his drone.

A use-by date is indicated on each POD. Dronavia declines all responsibility and voids the warranty on your system if your POD has exceeded this use-by date.

Whether your POD has been used after a deployment or has reached its annual maintenance deadline, you can exchange it for a new POD at a preferential price. Simply purchase a POD exchange and send us your POD. Once we receive it, we will ship your replacement POD.

For this POD model, only the parachute canopy must be returned. Please keep the parachute module and send only the used canopy.

Exception: for the Kronos M4D system, the entire POD must be returned, including both the parachute canopy and the carbon fiber tube.
