Option A ROCK Robotic

ROCK Ultra

Flagship Aerial LiDAR

The ROCK Ultra is the flagship aerial LiDAR of the ROCK line: a 1,000 m measurement range at 80% reflectivity, ≥7 returns and up to 1 million points per second for large-area mapping.

Pros

  • Longest published reach in the ROCK line
  • ≥7 returns for vegetation
  • Platform agnostic
  • ROCK Cloud processing
  • Enterprise support

Cons

  • Highest investment
  • Highest power draw (45 W typical)
  • More complex setup

Option B ROCK Robotic

ROCK R3 / R3 Pro V2

Professional Aerial LiDAR Options

The R3 V2 (16-laser) and R3 Pro V2 (32-laser) offer strong performance at accessible price points for standard survey work and smaller mapping projects. Both sheets publish the same 120 m measurement range; the Pro doubles the point rate.

Pros

  • Dual aerial (PPK) and handheld (SLAM) modes
  • ROCK Cloud integration
  • Two point-rate tiers
  • 26 MP camera included
  • DJI SKYPORT or Universal Mount

Cons

  • Shorter measurement range than Ultra
  • Two returns vs the Ultra's ≥7
  • Less suitable for large areas

Our Expert Verdict

Tie - Choose Based on Your Needs

The ROCK Ultra is the flagship for reach and canopy penetration — 1,000 m at 80% reflectivity and ≥7 returns. The R3 Pro V2 offers strong value for standard survey work at 640k/1,280k pts/s, and the R3 V2 is the accessible entry point at 320k/640k. Both R3 sheets publish the same 120 m measurement range at 60% reflectivity.

Choose ROCK Ultra if...

Choose ROCK Ultra for large-area mapping, utility corridors, and when maximum published range and return count are essential.

Choose ROCK R3 / R3 Pro V2 if...

Choose R3 V2 / R3 Pro V2 for standard survey work, construction, and budget-conscious LiDAR operations.

Frequently Asked Questions

Is the Ultra worth the extra cost?

For large-area mapping and long corridors, yes — it is the only ROCK sensor with a 1,000 m measurement range (at 80% reflectivity) and ≥7 returns. For smaller sites flown around 40 m AGL, the R3 Pro V2 delivers the same published 2-3 cm accuracy class.

Which works with DJI drones?

All three. ROCK publishes a DJI M300/M350 SKYPORT quick-release interface on the R3 V2, R3 Pro V2 and Ultra sheets, plus an optional Universal Mount (32 × 32 mm pattern) for other platforms.

How does ROCK Cloud compare to DJI Terra?

ROCK Cloud is the processing path bundled with ROCK sensors (500 GB for one year on the R3 and Ultra sheets); DJI Terra is the simpler route if you fly only DJI payloads such as the Zenmuse L2 or L3.

What accuracy should I expect?

ROCK publishes 2-3 cm system accuracy for all three: at 40 m AGL for the R3 V2 and R3 Pro V2, and at 120 m for the Ultra. None of the sheets condition those figures on ground control points — real-world results still depend on the flight plan, the GNSS solution and the control used.

Do I need RTK for ROCK LiDAR?

ROCK's sheets list PPK (post-processed kinematic) as the operating mode for all three sensors, with GNSS tracking across BDS, GPS, GLONASS and Galileo. Good base-station or CORS data is what drives the trajectory solution; ground control remains the independent check.

How much data does each sensor capture?

R3 V2: 320,000 pts/s single return, 640,000 dual. R3 Pro V2: 640,000 single, 1,280,000 dual. Ultra: up to 1,000,000 pts/s across a 100-1,000 kHz scanning frequency.
