YellowScan® Navigator | From Depths to Heights: Bathymetric & Topographic LiDAR Solution for UAVs
The YellowScan Navigator Bathymetric LiDAR is an innovative solution for exploring and mapping water surface, underwater topography, and ground topography with a single-button operation. Its compact and lightweight design allows for operating on various UAV platforms without compromising water penetration. Survey shorelines, rivers or ponds with ease, by obtaining simultaneous land and underwater topography.
Key Features:
- Topography and Water Mapping
- Easy to Use and Process
- Safe Operational Range
- Technologies Inside: SBG Systems / YellowScan Navigator Laser Scanner
Multi-Platform Adaptability
The Navigator can be used on multirotor or helicopter UAVs. The “quick release” GREMSY attachment allows for easy mounting on a wide range of drones.
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.
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.
44° FOV for High Precision
The Navigator Bathymetric system, with a 44-degree field of view, prioritizes 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.
High Autonomy for Maximized Efficiency
Optimize 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.
Embedded Camera
The Navigator features an embedded camera (global shutter) that can be used for colorization purposes.
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
Optimize your bathymetric capabilities using YellowScan CloudStation software, which includes automatic water classification. This functionality streamlines the categorization of water bodies, enhancing the efficiency and precision of bathymetric mapping.
Automated Water Surface Detection
The Navigator's software capability for automated water surface detection efficiently identifies water boundaries, streamlining data analysis for precise bathymetric mapping.
Advanced Calibration
All YellowScan systems are calibrated before shipment and come with a calibration certificate. Be ready to fly your system as soon as you receive it!

FAQ
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 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).
