The Freefly Flux H1 is a professional-grade aerial LiDAR sensor delivering survey-grade accuracy in a sub-700g package. Built around the Hesai XT-32MX 32-beam scanner, the Flux H1 captures dense, high-fidelity point clouds at 1.92 million points per second with triple returns, ±1 cm accuracy, and ±0.5 cm precision — resolving canopy from ground, distinguishing thin assets like cables and handrails, and producing clean, uniform geometry that holds up to scrutiny. With a maximum range of approximately 300m (984 ft), a wide 360° × 40.3° field of view, dual full-band GNSS receivers with PPK post-processing, and a 20 MP Ximea RGB camera for colorized deliverables, the Flux H1 is purpose-built for survey, mapping, inspection, and enterprise workflows where centimeter-level precision is non-negotiable. At approximately 690g (~24.3 oz), it mounts via the integrated Smart Dovetail interface to Freefly Astro and Astro Max. No calibration passes required, no software subscriptions, no ongoing maintenance fees. Designed, assembled, and tested in-house by Freefly in Woodinville, WA.

FAQ
What aircraft is the Flux H1 compatible with?
The Flux H1 mounts via the integrated Smart Dovetail interface and is compatible with Freefly Astro and Astro Max. It can also be used on other MAVLink-compatible aircraft with the appropriate interface cable. Contact us to discuss your specific platform.
What is the difference between the Flux H1, O1, and L1?
The Flux H1 (Hesai XT-32MX) offers the best accuracy in the Flux lineup at ±1 cm with triple returns, 1.92M pts/sec, and the longest range at 300m — making it the top choice when survey-grade precision and range are the priority. The Flux O1 (Ouster OS1) delivers the highest point density at 5.2M pts/sec with ±3 cm accuracy, 200m range, and is NDAA/DIU Blue compliant for government and regulated environments. The Flux L1 (Livox Avia) is the entry-level option with 240K pts/sec, 450m detection range, and non-repetitive scanning for power lines and hard-to-image assets. All three share the same streamlined workflow, Smart Dovetail mount, GNSS PPK, 20 MP RGB camera, and iPad processing with no subscription fees. Contact us to determine which sensor best fits your mission requirements.
Why does the Flux H1 have triple returns?
Triple returns allow the Hesai XT-32MX scanner to detect multiple surfaces from a single laser pulse — for example, registering the top of a tree canopy, mid-level branches, and the ground surface in a single shot. This is particularly valuable for forestry, vegetation mapping, terrain modeling under canopy, and any environment where you need to distinguish overlapping surfaces. Triple returns produce richer, more complete point clouds compared to single or dual return systems.
Is the Flux H1 NDAA compliant?
No. The Flux H1 uses the Hesai XT-32MX scanner, which is not NDAA compliant. If you require NDAA and DIU Blue compliance for government, public safety, or Department of Defense operations, see the Flux O1 (Ouster OS1), which is both NDAA compliant and DIU Blue UAS listed. Contact us to discuss which option is right for your compliance requirements.
Do I need a software subscription to use the Flux H1?
No. The Flux H1 has no software subscription fees and no ongoing maintenance costs. Processing tools are included with the sensor, and data is exported in standard LAS or LAZ formats compatible with any point cloud software. You will need an Apple iPad with an M-series chip for on-site processing.
How fast can I process data in the field?
Processing is fast enough to deliver results on-site before you leave. In Freefly’s testing, an M3 iPad processes flight data at roughly 4× real time — so an 8-minute flight takes approximately 2 minutes to process. Simply remove the USB-C drive, import into the Flux app on your iPad, add your RINEX file for GNSS post-processing, and review your point cloud.
Does the Flux H1 require calibration before each flight?
No. The Flux H1 requires no calibration passes or special flight patterns. Take off vertically, fly directly to your first waypoint, and begin surveying. The system automatically syncs IMU, GNSS, and LiDAR data, and advanced processing ensures strips align correctly every time.
What makes the Flux H1 a good choice for traveling to job sites?
At under 700g, the Flux H1 is one of the lightest professional-grade LiDAR systems available. Combined with the compact Astro platform, the entire mapping system travels easily to job sites anywhere in the world. The Flux H1 ships in a rugged travel case with all required accessories.
