The YellowScan Mapper Ultra is a long-range UAV LiDAR system built for high-performance aerial mapping over large areas. It combines a 640 m laser range, a 75° scanner field of view, and up to 7 true echoes per shot for outstanding vegetation penetration, paired with an SBG Quanta Micro GNSS inertial solution that delivers 2.5 cm precision and 2.5 cm accuracy. A lightweight 1,950 g body (batteries excluded), an integrated 3.5" touchscreen, and an embedded global-shutter RGB camera make it fast to deploy and simple to run in the field across multi-rotor, VTOL, fixed-wing, and single-rotor platforms.
Long-range UAV LiDAR with a 640 m laser range, 75° field of view, 7 true echoes, and 2.5 cm accuracy. Map faster, go further, and see through vegetation.

Applications
- Forestry and ground mapping. With 7 true echoes, the Mapper Ultra reveals the ground beneath dense vegetation to generate accurate terrain models, even in heavily forested areas.
- Corridor and utility inspection. Inspect corridors and critical infrastructure at 120 m height and 10 m/s, mapping powerlines, pipelines, and utility networks with high point density and reliable coverage.
- Engineering. Map long distances faster without compromising detail, operating efficiently over extended infrastructure even in challenging terrain with elevation changes.
- Complex terrain mapping. A flexible topographic LiDAR system that performs reliably across hills, valleys, and uneven terrain, maintaining consistent data quality where traditional mapping becomes difficult.

FAQ
How accurate is the Mapper Ultra?
It delivers 2.5 cm precision and 2.5 cm accuracy using its SBG Quanta Micro GNSS inertial solution, measured 1s at 50 m, nadir. Precision (reproducibility) accounts for the variation in successive measurements on the same target; accuracy is the conformity of a measured position to its true value.
How does it see through vegetation?
The system records up to 7 true echoes per laser shot. Multiple returns let the LiDAR capture points on the canopy, mid-story, and the ground beneath, which is what allows it to generate accurate terrain models in heavily forested areas.
What is the range and typical flight height?
The laser range is 640 m. Typical flight height is 120 m at a typical flight speed of 10 m/s, with a maximum recommended flight height of 240 m. Maximum flight height varies with the selected pulse repetition rate (PRR); the 240 m figure is given at 100 kHz PRR.
What point density can I expect?
Around 300 pts/sqm at 50 m AGL and 10 m/s. Density depends on flight height and speed: at 500 kHz PRR and 10 m/s, expect roughly 1086 pts/m² at 30 m, 465 at 70 m, and 217 at 150 m. Flying faster reduces density proportionally.
Which drones is it compatible with?
The Mapper Ultra is designed to integrate across multi-rotor, VTOL, fixed-wing, and single-rotor UAVs. Attachment schemes are available for platforms such as Gremsy and Freefly. A stand-alone mounting bracket and quick-release adapters are available as optional accessories.
How is data stored and offloaded?
The system uses dual CFexpress storage (2 × 512 GB) for high-speed capture and larger projects. Two CFexpress cards are included in the package.
What software does it use?
The package includes SBG Qinertia for GNSS and inertial post-processing and CloudStation Essential for visualizing, inspecting, colorizing, and exporting data. CloudStation Pro and CloudStation Ultimate are available as upgrades, with Ultimate adding orthophoto generation and command-line (ytk) processing for automation and batching.
How long can it fly and what power does it need?
Battery autonomy is about 1 hour typical. The system runs on 10 to 34 V with a power consumption of 50 W, and operates from -10 to +40 °C. Two batteries are included.
