be ready to fly fast
Kronos M4 Parachute Recovery System (PRS) 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 Recovery Systems (PRS) 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 your payload
Kronos M4D Parachute Recovery System (PRS) has been designed to allow drone operators to always benefit from their payload and to carry an additional accessory for their flight missions.
Autonomous deployment
RTK compatible and payload available
Autonomous deployment system
Equipped with new autonomous deployment technology (mandatory for MOC 2512 (M2) compliance), Kronos PRS 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.
Black box for analysing flight logs
A time-stamped log system is built into the Kronos M4 parachute. It records the triggering actions performed by the user for diagnostic purposes. These logs can be analysed by Dronavia and sent on request.
EASA MOC2512 (M2) Compliance
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 2512 (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.
C5 Conversion Kit
To obtain C5 class label for your C2 class drone (DJI Matrice 4 series), the operator doesn’t need to install an accessory kit directly on his drone, but to convert it from C2 to C5 class.
To carry out this conversion, the C2-class drone must pass through our workshop or that of an approved reseller so that our experts can install the system on the drone.
Equipped with our PRS + FTS conversion kit (PRS-FTS-MOC Kronos AD Matrice 4), the DJI Matrice 4 drone becomes a Kronos AD Matrice 4 drone.
Patented & efficient CO2 triggering device
Numerous tests and successive improvements have brought this CO2 system to levels of reliability never before achieved on a Parachute Recovery Systems. The pressurized gas (60 bars!) is released in a fraction of a second to propel the parachute canopy out of its container.
The excess gas released (each cartridge contains several dozen litres) is used to accelerate the deployment of the canopy and minimise the loss of altitude when the parachute is triggered.
POD system
Resetting your Kronos M4 Parachute Recovery System takes just a few minutes. All you have to do is replace your triggered pod with a new one, and then carry out a few simple maintenance operations yourself, as explained and detailed in the parachute user manual.
You can either buy a new POD or exchange your deployed POD for a new one at a special price.
Secure transmission with Klick system
The communication system between the triggering remote control and the PRS / FTS is based on advanced technology and LoRa modulation.
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.
Long range with Klick system
The range between the Klick trigger remote control and the PRS / FTS, allowing manual activation of Dronavia systems, can be up to 1.5km, in optimal conditions and in an unobstructed, interference-free environment.
Dronavia offers a ‘Klick Ultra’ option for a range of up to 10 kilometres under optimum conditions in an unobstructed, interference-free environment.
SDK Module
An SDK connection is established via the USB-C cable linking the parachute to the DJI Matrice 4 drone. This connection enables the drone’s motors to be switched off instantly and autonomously when the parachute is deployed.
