PARACHUTE RECOVERY SYSTEM

The Kronos MVC3 parachute model is part of a new generation of innovative rescue parachutes, equipped with an autonomous deployement system capable of automatically detecting a crash, following a loss of altitude, a collision or an abrupt change of angle. Compatible with all DJI Mavic 3 Enterprise drones (3E / 3T / 3M) / DJI Mavic 3 Pro / DJI Mavic 3 Pro Cine, it is the most reliable and easy-to-use system on the market to protect your drone.

be ready to fly fast

The parachute  is assembled in just a few minutes by the pilot himself, without the drone ever having to pass through our workshop. The Kronos MVC3 parachute system can be installed and uninstalled in less than 2 minute. Dronavia provides video installation tutorials as well as a user & instruction manual to make it easy to get started.

STAY FOCUS ON YOUR JOB

To reduce activation time and increase the chances of avoiding a crash and accident, Kronos parachute systems incorporate an autonomous deploiement technology. This module triggers the parachute in less than 0.27 seconds, compared with around 3 seconds for a human trigger. Stay one step ahead and fully focused on your flying missions.

Keep flight EFFICIENCY

Weighing just 130 grams, the Kronos Mini parachute has been designed to be as light as possible, so you don’t have to compromise your flying performance.

Autonomous deployment system

Equipped with new autonomous deployment technology (mandatory for MOC M2 compliance), Kronos parachutes and FTS activate automatically in less than 0.27 seconds in the event of a problem. This is a significant reduction compared with the average human time of 3 seconds, and also enables a considerable reduction in the drone’s impact energy.

A soft & controlled landing

The new PARA² canopies used in Kronos parachute systems are the result of 3 years of development. Their innovative, ultra-light design and unique construction give PARA² canopies superior efficiency and stability.

The fall rate is minimised in relation to the canopy surface. Each Kronos parachute is designed so that the canopy(s) keep the drone as flat as possible during its fall in order to minimise damage on impact.

Long-range, secure transmission

The long-range communication system between the trigger remote control and the parachute/FTS is based on advanced technology and LoRa modulation. Its range can reach several kilometres in optimal conditions and a long range option allows to exceed 10 km.

The communication protocol is based on the 869 MHz frequencies, which are free of authorisation (433 and 915 MHz options available). A 128-bit encryption ensures that the data is not intercepted and the user is warned if the communication is disturbed.

Compliance with EASA MOC M2

EASA has published a new proposed means of compliance for systems installed on drones to reduce ground impact in the event of a crash. The document is aimed at drone operators who are considering fitting a drone with a parachute or demonstrating that the drone has a feature that reduces its impact energy in the event of a crash. The document is also intended for drone manufacturers and manufacturers of mitigation systems (parachute recovery systems).

The MOC M2 designates the level of robustness required for the safety system in the event of the drone losing control and falling to the ground.

Depending on the level of robustness, a correction value can reduce or increase the GRC. The more effective the measures, the higher the correction value and the lower the GRC. If the final GRC is greater than 7, it is not possible to request a SORA.

The assessment of the ground risk class (GRC) is covered by stages 2 and 3 of the SORA. The first step covers the definition of the intrinsic GRC, which is the initial level of ground risk, while the second covers the mitigation measures that can be applied to reduce the risk and achieve the final GRC.

Obtain your C5 class marking

To obtain a class C5 marking for your DJI Mavic 3 Enteprise (3E / 3T / 3M) drone, it’s not a question of the operator installing an accessory kit directly, but of a conversion from C2 to C5.

To carry out this conversion, the DJI Mavic 3 drone must pass through our workshop so that our experts can install an internet FTS and PRS.

So, fitted with our PRS and FTS (PRS-FTS-MOC Kronos AD Mavic 3) kit, the DJI Mavic 3E becomes a Kronos AD Mavic 3E and the DJI Mavic 3T a Kronos AD Mavic 3T.

In order to achieve C5 compliance, we started from scratch and checked all the requirements for class C5 for the drone + PRS + FTS package (unlike a kit, for which you only need to check the requirements for the kit alone).

You retain your DJI warranty, simply dismantle the FTS + PRS assembly before sending it in for warranty.

What regulations do Dronavia Parachute Recovery Systems Kronos MVC3 (PRS) comply with?

The Kronos MVC3 (PRS) Parachute Recovery System for DJI Mavic 3 complies with the MoC2512 (M2) for M2 mitigating means published by EASA. It facilitates the implementation of the Specific Operations Risk Assessment (SORA). The MoC2512 (M2) demonstrates the drone’s ability to reduce impact energy in the event of a crash.

By combining the Parachute Recovery System (PRS) and the Flight Termination system (FTS), Dronavia has created a C5 conversion kit to convert your DJI Mavic 3 Enterprise (3E / 3T / 3M) drone from class C2 to class C5, enabling you to fly in the specific category in the STS-01 scenario.

What is a MOC (Means of Compliance)?

A MoC is a way for professional drone operators to demonstrate that they comply with the regulations and standards that apply to their activities and to guarantee the quality and safety of the products they use. To obtain it, it is necessary to meet the current regulatory requirements published by the EASA, the European Union Aviation Safety Agency.

Beyond quality and safety, with a MOC compliant product, professional drone operators can obtain a SORA (Specific Operations Risk Assessment) or PDRA (Pre-Defined Risk Assessment), a flight authorization delivered for specific missions, in an easier and faster way.

What is the Ground Risk Class (GRC)?

The Ground Risk Class (GRC) assessment is covered by the steps #2 and #3 of the SORA. The first step covers the definition of the Intrinsic GRC which is the initial level of ground risk, while the second one covers the mitigations that can be applied to reduce the risk and obtain the Final GRC.

How does the Kronos MVC3 Parachute Recovery System (PRS) protect my drone?

All our Parachute Recovery Systems (PRS) enable an emergency landing following an in-flight problem, by drastically limiting impact energy.

To limit impact energy, the new Kronos PRS systems incorporate autonomous deployment technology. This technology automatically deploys the parachute in less than 0.27 seconds, compared with around 3 seconds for human deployment, in the event of a problem during flight.

The new PARA² canopies used in Kronos Parachute Recovery Systems (PRS) are the result of three years’ development. Their innovative, ultra-light design and unique composition give PARA² canopies superior efficiency and stability. The rate of fall is minimized in relation to the surface area of the fabric. Dronavia Parachute Recovery Systems (PRS) are designed so that the canopy keeps the drone as flat as possible during its fall, to minimize impact damage.

However, Dronavia cannot guarantee that your drone will remain flat during its fall. This depends on weather and deployment conditions (height, type of ground, etc.).

How does the Kronos MVC3 Parachute Recovery System (PRS) work?

To reduce activation time and increase the chances of avoiding a crash or accident, Dronavia Parachute Recovery Systems (PRS) incorporate autonomous deployment technology. This technology automatically deploys the parachute in less than 0.27 seconds, compared with around 3 seconds for human deployment, in the event of a problem during flight.

For total safety, Kronos Parachute Recovery Systems (PRS) can also be deployed manually, using a Klick trigger remote control. Ergonomic, lightweight, with LED status indicators and a secure wireless connection, the Klick trigger remote control range enables drone operators to ensure the safety of their flights, thanks to rapid, controlled deployment.

How does Dronavia's autonomous Parachute Recovery System Kronos MVC3 (PRS) deployment technology work?

This technology automatically deploys the parachute in less than 0.27 seconds, compared with around 3 seconds for human deployment, in the event of a problem during flight.

Here are just a few of the elements taken into account by our autonomous deployment technology: gyroscope, accelerometer, magnetometer, barometer, temperature, humidity, etc.

Dronavia’s autonomous deployment technology has been tested to EASA standards.

How does the Kronos MVC3 Parachute Recovery System (PRS) deploy?

Kronos MVC3 Parachute Recovery Systems (PRS) are deployed by a powerful pre-stressed spring system. Numerous tests and successive improvements have brought this ejection system to levels of reliability never before achieved for a PRS.

What communication system is used to link the Dronavia Parachute Recovery System (PRS) to the Klick trigger remote control?

The long-range communication system between the Klick trigger remote control and the Parachute Recovery Systems (PRS) is based on advanced technology and LoRa modulation. It has a range of up to 5 kilometers under optimum conditions, with a long-range option for over 10 kilometers.

The communication protocol is based on license-free 869 MHz frequencies (433 and 915 MHz options available). 128-bit encryption ensures that data cannot be intercepted. The user is warned if communication is disrupted.

Can the Klick trigger remote control be interfered with and/or intercepted? Is there a risk of accidental deployment?

No, all data is encrypted using a secure wireless link based on advanced technology and LoRa modulation. 128-bit encryption ensures that data cannot be intercepted. The user is warned if communication is disrupted.

How to rearm Kronos MVC3 Dronavia Parachute Recovery Systems (PRS)?

Rearming the Kronos MVC3 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.

How do I exchange my POD?

Whether your POD is used or needs annual maintenance, you can exchange it for a new POD at a preferential price.

Buy a POD exchange and send us your POD. When we receive your POD, we’ll send you the new POD.

Why equip your drone with a Kronos MVC3 Parachute Recovery System (PRS)?

Adding a Parachute Recovery System (PRS) to a drone can help ensure safety in the event of a technical failure or critical problem during flight (extreme weather conditions, radio transmission failure, technical failure of the propulsion system, loss of GPS signal, etc.).

Parachute Recovery Systems (PRS) help attenuate impact and minimize damage to the drone and its environment in the event of an emergency landing. They can also help protect nearby people in the event of a problem during flight.

What is the C5 class published by EASA?

From January 1, 2024, a new drone class, Class C5 (for specific category flights (STS-01)), will come into force throughout Europe.

The STS-01 scenario concerns line-of-sight flights at an altitude of 120 meters, whether in a populated or unpopulated environment. This flight scenario is comparable to the DGAC’s current S3 scenario.

To fly in this scenario in Europe, you need to obtain a C5 marking for your drone. There are two ways of doing this: either the manufacturer develops his drone to meet the requirements of this class, or the drone operator installs an accessories kit (or conversion kit) on his C2 or C3 class drone (DJI Mavic 3 Enterprise/ DJI Matrice 350 / DJI Inspire 3), enabling his drone to become C5 class compliant and obtain this marking.

Dronavia is proud to be the first manufacturer to offer accessories kits or conversion kits (consisting of a parachute system (PRS) and a Flight Termination System (FTS)) compliant with EASA regulations, enabling your drone to obtain the C5 class label.

How can I get Class C5 label class for my DJI Mavic 3 Enterprise (3E / 3T / 3M) drone?

To obtain C5 class label marking for your DJI Mavic 3 Enterprise (3E / 3T / 3M) drone, the operator doesn’t need to install an accessories kit directly on his drone, but to convert it from C2 to C5 class.

To carry out this conversion, the DJI Mavic 3 Enterprise (3E / 3T / 3M) drone must pass through our workshop (or that of an authorized reseller) so that our experts can install an internal Flight Termination System (FTS).

So, equipped with our PRS + FTS accessories kit (PRS-FTS-MOC Kronos AD Mavic 3), the DJI Mavic 3E drone becomes a Kronos AD Mavic 3E drone, the DJI Mavic 3T drone becomes a Kronos AD Mavic 3T drone and finally the DJI Mavic 3M drone becomes a Kronos AD Mavic 3M drone.

To achieve C5 conformity, Dronavia started from scratch, checking all the requirements of class C5 for the drone + PRS + FTS package (unlike an accessories kit, for which it is sufficient to check the requirements for the accessories kit alone).

In the event of a DJI after-sales service, you retain your DJI warranty. Simply dismantle the entire C5 conversion kit (PRS + FTS) before sending it in under warranty.

Do I keep the warranty on my DJI drone when I upgrade it to C5 class?

In the event of a DJI after-sales service, you retain your DJI warranty. Simply dismantle the entire C5 conversion kit (PRS + FTS) before sending it in under warranty.

What is the MOC2512 (M2) published by EASA?

EASA has published a new compliance proposal for systems installed on drones to reduce ground impact in the event of a crash. The document is aimed at drone operators planning to fit a drone with a parachute, or to demonstrate that the drone is equipped with a function that reduces its impact energy in the event of a collision. The document is also aimed at drone manufacturers and manufacturers of Parachute Recovery Systems (PRS).

MOC2512 (M2) designates the level of robustness required for the safety system in the event of a drone losing control and falling to the ground.The three key elements of an effective M2 mitigation system are as follows:

  • Reduce the effect of ground impact
  • Operate reliably in the event of loss of control
  • Do not introduce any additional risk

Drone manufacturers must declare that they meet these three requirements and provide evidence, in the form of tests, analyses, simulations, inspections, design reviews or operational experience, to back up these declarations.

How to reduce GRC scores with MOC2512 (M2) and obtain a SORA (Specific Operations Risk Assessment)?

Mitigation measures are divided into three stages:

M1 – Strategic mitigation: this stage involves implementing strategies to reduce risks at source. For example, by choosing flight routes that avoid high-risk areas, or by using technologies that reduce the risk of accidents.

M2 – Reducing effects in the event of an impact: this stage aims to minimize the consequences of an accident should it occur. For example, by using containment devices to protect people and property on the ground, or by implementing evacuation plans in the event of an accident.

M3 – Contingency planning: this stage involves putting in place protocols to manage the consequences of an accident and ensure the safety of people and property on the ground. For example, by providing emergency communications or establishing working relationships with local authorities and emergency services.

Each of these steps has a corrective value, which can reduce or increase the GRC depending on the strength of the measures put in place. The more effective the measures, the higher the correction value and the lower the GRC. If the final GRC is higher than 7, it is not possible to apply for a SORA file.

How does automatic takeoff detection work on the Kronos MVC3 Parachute Recovery System (PRS)?

The Kronos MVC3 Parachute Recovery System (PRS) is equipped with automatic takeoff and landing detection technology, to prevent inadvertent deployment of the parachute system (PRS). The parachute autonomously detects the drone’s take-off and landing (vibration, propellers, altitude, etc.). It activates and deactivates automatically without human intervention. The only action required of the drone operator is to switch on the parachute.

How do I install a Kronos MVC3 Parachute Recovery System (PRS)?

The Kronos MVC3 Parachute Recovery System (PRS) can be installed and uninstalled in less than a minute. Simply attach the adhesive bracket to the front of your drone, clip the parachute onto the bracket, loop the lines around the drone and switch on the Kronos MVC3 Parachute Recovery System (PRS).

Dronavia provides a user manual and tutorial videos to help drone operators carry out the installation on their drone, simply and quickly.

How do I switch off the drone's power supply to the drone's motors while the Kronos MVC3 Parachute Recovery System (PRS) is deploying?

Dronavia markets Flight Termination systems (FTS) compatible with its Parachute Recovery Systems (PRS), enabling the drone’s power supply to be cut off in less than a second. The two systems are paired and coupled in our workshop by our experts.

If the Flight Termination System (FTS) is activated, the Parachute Recovery System (PRS) is also automatically deployed (and vice versa).

Does the Kronos MVC3 Parachute Recovery System (PRS) require a power supply?

The Kronos MVC3 Parachute Recovery System (PRS) features an independent 10-hour battery that can be recharged via USB-C.

Can I travel by plane with a Dronavia Kronos MVC3 Parachute Recovery System (PRS)?

There are no constraints for drone operators traveling by air. Most airlines offer the option of putting the Kronos MVC3 Parachute Recovery System (PRS) in the hold or in the cabin.

How do I carry out maintenance on Kronos MVC3 Parachute Recovery Systems (PRS)?

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.

In both cases, you can either buy a new POD, or exchange your used POD for a new one at a preferential price.
