YellowScan Navigator

Depths to heights: operating
bathymetric LiDAR with one button.

The YellowScan bathymetric LiDAR is an innovative solution for exploring underwater and ground topography with a single-button operation. Its lightweight design allows for versatile platform selection without compromising water penetration.

AGL altitude

Up to 100m

System precision


System accuracy


Battery weight excl.


Multi-platform adaptability

The YellowScan Navigator system can be used on multirotor or helicopter UAVs. When it comes to drones, the 'quick release' GREMSY attachment allows for easy mounting on a wide range of drones, with the standout choice being the Acecore Noa.

Simultaneous land & water survey

The YellowScan Bathymetric system is designed for conducting bathymetric measurements in shallow waters and is rapidly deployable on a UAV. This full waveform LiDAR system ensures continuity between underwater points and the surrounding terrain.

High autonomy for maximised efficiency

Optimise your bathymetric survey operations with YellowScan's LiDAR system, delivering a 45-minute autonomy on a single battery charge for extended underwater data collection in various marine settings.

44° FOV for high precision

YellowScan's bathymetric system, with a 44-degree field of view, prioritises precision over a broader angle. This decision is based on the fact that 44° is the maximum angle for a green laser to perform effectively underwater. Beyond this angle, the laser’s penetration depth in water is significantly affected, limiting the system’s overall performance.

Diverse water environments

Intended for aerial use on drones, the system covers various water areas such as shorelines, rivers, lakes, estuaries, ponds and gravel pits. Navigator is user-friendly and adaptable for a wide range of applications, from hydrographic surveys to underwater resource management.

Embedded camera

The Navigator features an embedded camera with a global shutter, allowing the pointcloud to be colourised.

Underwater point correction

The underwater point correction in the CloudStation refines submerged data points, taking into account water refraction and ensuring reliable bathymetric mapping with uncompromised accuracy.

Automated water classification

Optimise your bathymetric capabilities using YellowScan CloudStation software, which includes automatic water classification. This functionality streamlines the categorisation of water bodies, enhancing the efficiency and precision of bathymetric mapping.

Automated water surface detection

YellowScan's software’s capability for automated water surface detection efficiently identifies water boundaries, streamlining data analysis for precise bathymetric mapping.

Advanced calibration

All of YellowScan's systems are calibrated before shipment and come with a calibration certificate. Be ready to fly your system as soon as you receive it!

On-site training

YellowScan delivers complete training to new customers. The training is provided over 2 days and can take place at your premises or online.

Technical support

YellowScan's 1 year unlimited technical support from it's experts enables you to confidently undertake your projects, whether you are new or experienced in the field.


What is a bathymetric LiDAR?

Based on visible green light emission, bathymetric LiDAR enables the measurement of topography under water. This allows for crucial mapping of coastlines with continuity under water.

Why a green laser?​

Water “absorbs” certain light wavelengths much more than others​. Depending on the water, absorption varies as well, however a trend is usually blueish-green penetrates the most​.

What is the laser class of this LiDAR system?

The YellowScan Navigator is a Class 3B laser product.​ Appropriate eyewear protection is mandatory to avoid eye injuries from the laser beam. ​Do not use sunglasses for laser protection and quickly proceed to get the drone at 30m AGL to ensure Nominal Ocular Hazard Distance (NOHD).​ Always make sure nobody is within 25m of the drone or LiDAR while active. ​

What are the typical applications?

The applications are many and varied. The YellowScan Navigator system can be used for river and lake analysis, coastal oceanography, safety of hydraulic structures, submarine archaeology, surface water hydrology, dredging and marine works.

What is a Secchi?

The Secchi Disc​ was created by Angelo Secchi and used to measure water transparency / turbidity in bodies of water​. The marine Secchi disc is a plain white, ø30 cm disc mounted on a pole. The freshwater Secchi disc is ø20 cm and features black quadrants.

A Secchi is the depth at which it is not possible to distinguish the disc in water​. This depth varies according to the water’s turbidity​ and subjectively distinguishing the disc by the observer​.

For example, if 1 Secchi is 2.2m under water, a 2 Secchi system will be able to measure up to 4.4m underwater approximately.

Is this system compatible with DJI M300/M350?

No, we do not recommend mounting the YellowScan Navigator system on the DJI M300/350 drone. The weight of the system (incl. battery) exceeds the manufacturer’s recommended maximum payload capacity (2.7 kg).
