Marlyn is an industrial grade photogrammetry drone that makes the surveying process easy, efficient and straight forward. Marlyn takes away the hassle and risks that come with the take-off and landing of conventional fixed winged drones, without compromising the unprecedented performance of an aerodynamically optimized wing.
Our engineers have put great care in the integration of different cameras with our end goal in mind: allowing professionals across all industries to perform detailed analyses and precise measurements with high realiability and ease of use.
This is also reflected in our flight control software, MarLynk, that makes planning and controlling the drone straight forward and intuitive.
Without Marlyn, it would not be possible for us to map Silhoutte island, which is known as a tropical island with rough conditions.

We want our customers to be flying as much as possible, even in the most challenging weather conditions. That's why Marlyn is the only hybrid drone in its class capable of handling wind speeds up to 6Bft (45 km/h) during take-off, landing and cruise. In our design we have chosen for a transition of the whole body of Marlyn instead of transitioning each of the engines separately or carrying extra engines for different flight regimes. The advantage of this is that it limits the mechanical complexity, maximises reliability and minimises maintenance requirements.
As a result, Marlyn is equipped with only four small electric motors for propulsion, which need far less maintenance compared to gasoline alternatives. In the forward flight mode, two of the motors are even deactivated to save more power.
The drone is fully electric and is powered by our in-house developed smart dual battery system, which means that two batteries can be placed in the drone to provide for redundancy: the one functions as a failsafe for the other and vice versa. Moreover, each battery is equipped with a battery management system that closely monitors the state of charge of the battery to know exactly how much flight time is left. Know where you stand and fly with peace of mind!
Marlyn captures geo-referenced aerial images with resolutions down to 1.5 cm (0.6 in), which are transformed into point clouds with millions of data points for each single flight. Even more time can be saved by using the survey grade Marlyn equipped with Post Processed Kinematics (PPK).
This version comes with an integrated high end GNSS receiver which allow to apply GPS data corrections by using data from a base station or VRS to achieve absolute X, Y, Z accuracy of down to 3 cm (1.2 in). The advantage of PPK compared to Real Time Kinematics (RTK) is that it does not need a live communication link that always has a chance of being disconnected or unstable.
With the higher accuracy of PPK, fewer to no ground control points are needed to adequately georeference your survey, further reducing time in the field.
The MarLynk planning software allows you to easily and intuitively generate the most efficient flight plan for your project. Define the boundary of the region you want to map, specify the ground resolution and overlap and you’re ready for lift-off!
Take Marlyn out of her protective travel case, attach the two wings and place her on the ground. Our brief and smart checklist guides you through the final steps, ensures flight safety and even makes sure you don’t forget to take off the lid from the lens!
With a simple push of a button Marlyn takes off vertically like a helicopter. No need to hand launch the drone or carry a bulky catapult to the project site!
After the take-off, Marlyn performs the transition in mid-air and starts gathering the desired images, all completely automatically. Our in-house developed autopilot continuously monitors flight data using the on-board sensor suite and guides Marlyn along the predefined flight plan. During flight you will stay up-to-date with flight info, such as position, altitude, battery state-of-charge and image capturing progress. As operator, you’ll remain in control and abort the automatic flight mode at any time to hold position, return to home, land or fly further manually.
After the controlled and automatic landing at the indicated landing spot, the images and positional data is automatically organized, resulting in geo-tagged images that can be imported into your preferred image processing software.
This post processing software transforms the data captured by Marlyn into an orthophoto, digital surface model, point cloud or other output that is compatible with a wide range of industry software suites.
The generated (3D) models can now be used to provide actionable insights by measuring distances, performing volumetric analyses, taking cross-sections and more.
We want to give professionals across all industries access to data gathered from the skies, by making the data gathering process as easy as possible.
With this vision in mind, we have fully automated the flight and we are offering an accompanying software suite, MarLynk, that makes it easy and user-friendly to plan and control a project.
MarLynk is specifically built for surveying projects: planning missions is intuitive and key surveying parameters can be changed at a glance
A solid pre-flight checklist helps to maximise flight safety and success of your mapping flights
Plan missions in mountainous regions by displaying local elevation data as you go
Allows flight to be automated from take-off to landing. An assisted take-off or landing is also possible if preferred
