Fly High, Plan Simple.
The Ultra's 1,000m range transforms your workflow. Fly confidently at maximum legal altitude (400ft / 120m AGL), simplifying mission planning over complex terrain and eliminating risks from unmapped obstacles like power lines or cell towers. The 1550nm wavelength is 40x safer than 905nm systems, allowing higher power output without eye safety concerns.
Penetrate the Impenetrable.
With ≥7 echo returns—the highest in the UAV LiDAR industry—and a powerful 1550nm laser, the Ultra captures the true ground where other systems fail. Each additional return increases the probability of detecting bare earth through vegetation. Reliably map through dense forest canopies to produce the cleanest bare-earth models you've ever seen.
An End-to-End Ecosystem.
The Ultra is seamlessly integrated into the ROCK workflow. Pre-process in the field with ROCK Desktop, then upload to ROCK Cloud to store, analyze, and order professional deliverables like DTMs, contours, and planimetrics with a single click. At just 1.21kg (sensor only) or 1.40kg with 26MP camera, it's 60% lighter than competing long-range systems.

Frequently Asked Questions
Is the ROCK Ultra better than the R3 Pro?
They serve different purposes. The R3 Pro excels at high-density, low-altitude scans for detailed inspections. The Ultra is designed for large-area mapping with high-altitude efficiency, making it ideal for surveying, forestry, and civil engineering projects.
What drones are compatible with the ROCK Ultra?
The Ultra is compatible with most commercial drones including DJI M300, M350, and similar platforms. At just 1.4kg with camera, it maintains excellent flight performance while delivering professional-grade LiDAR data.
How much area can I cover in a single flight?
With its 1000m range, the Ultra can cover 200-300 acres in a single 30-minute flight at 120m AGL. Flying at the maximum 450m altitude, you can cover up to 1000 acres per flight—that's 2-3x more coverage than traditional 905nm LiDAR systems.
Why is 7 returns better than 5 returns?
Each additional return increases the probability of capturing ground points through vegetation. While 5-return systems often miss the ground in dense canopy, our 7-return capability ensures reliable bare-earth detection even in the thickest forests, reducing the need for manual classification and repeat flights.
