The Freefly Flux L1 is an entry-level professional LiDAR sensor that makes aerial 3D mapping accessible without compromising on capability. Powered by the Livox Avia scanner, the Flux L1 offers extended 450m range, a wide 70.4° × 77.2° field of view, and both repetitive and non-repetitive scanning modes — making it especially well suited for power line inspection, forestry, corridor mapping, and other hard-to-image assets. At approximately 715g, it mounts via the integrated Smart Dovetail interface to Freefly Astro, Astro Max, and Alta X platforms. The Flux L1 features dual full-band GNSS receivers with PPK post-processing, a 20 MP Ximea RGB camera, low-noise IMUs, and on-site data processing via Apple iPad — go from scan to decision in minutes, right in the field. No calibration passes required, no software subscriptions, no ongoing maintenance fees. Designed, assembled, and tested in-house by Freefly in Woodinville, WA.
The lightest, simplest LiDAR workflow — scan, process, and deliver point clouds on-site in minutes.
Features
- Livox Avia LiDAR scanner with up to 240,000 points per second and triple-echo returns for enhanced data capture through vegetation, canopy, and dense environments
- Extended detection range up to 450m (in low-light conditions) — fly higher for greater efficiency or maintain safe standoff from assets
- Wide 70.4° × 77.2° field of view for maximum coverage per pass, reducing the number of flight lines needed
- Dual scanning modes: repetitive mode for high-precision mapping of terrain, construction sites, and agricultural fields; non-repetitive mode for complete coverage of complex structures like power lines, cables, and thin assets that are difficult to capture with traditional LiDAR
- ±5 cm accuracy and ±2 cm precision — reliable point cloud quality for surveying, inspection, and volumetric measurement
- Dual full-band GNSS receivers (L1/L2/L5/L6) with PPK post-processing via dual u-blox X20 modules integrated into each antenna for centimeter-level georeferencing
- 20 MP Ximea RGB camera for colorized point clouds and visual QA of deliverables
- Low-noise IMU system automatically syncs with GNSS and LiDAR data — no calibration passes or complex flight patterns required; fly directly to your first waypoint and start surveying
- On-site processing via Apple iPad (M-series) — import data from the USB-C flash drive, add RINEX file for GNSS post-processing, and visualize results in minutes while still in the field
- Data stored on removable 256 GB USB-C flash drive; export to standard LAS or LAZ point cloud formats
- No software subscription or maintenance fees — the workflow and processing tools are included with the sensor
- Compact at approximately 715g with integrated Smart Dovetail mount — optimized for long flights on Freefly Astro, Astro Max, and Alta X platforms
- Designed, assembled, and tested in-house by Freefly in Woodinville, WA, USA
- Class 1 laser product (905 nm) per IEC 60825-1:2014 — considered eye-safe, though prolonged direct viewing and use of optical instruments to view the laser should be avoided

FAQ
What aircraft is the Flux L1 compatible with?
The Flux L1 mounts via the integrated Smart Dovetail interface and is compatible with Freefly Astro, Astro Max, and Alta X platforms. 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 L1, H1, and O1?
The Flux L1 (Livox Avia) is the entry-level option with extended 450m range and non-repetitive scanning — ideal for power lines, forestry, and hard-to-image structures. The Flux H1 (Hesai XT-32MX) offers higher point density (1.92M pts/sec), ±1 cm accuracy, and 300m range for survey-grade mapping. The Flux O1 (Ouster OS1) delivers the highest point density (5.2M pts/sec), ±3 cm accuracy, 200m range, and is NDAA/DIU Blue compliant for government and regulated environments. All three share the same streamlined workflow, Smart Dovetail mount, GNSS PPK, RGB camera, and iPad processing. Contact us to determine which sensor best fits your mission requirements.
What is non-repetitive scanning and why does it matter?
Non-repetitive scanning is a mode unique to the Livox Avia scanner in the Flux L1. Instead of scanning the same pattern repeatedly, the scanner traces a different path with each pass, so point cloud coverage approaches 100% over time. This is particularly valuable for imaging thin, linear assets like power lines, cables, handrails, and other structures that are difficult to capture completely with traditional repetitive scanning patterns. The L1 also supports a standard repetitive mode for conventional mapping applications.
Do I need a software subscription to use the Flux L1?
No. The Flux L1 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, the Flux L1 flew a scan area in approximately 7 minutes, and the data processed on an iPad in about 1 minute 40 seconds. 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.
Is the Flux L1 NDAA compliant?
No. The Flux L1 uses the Livox Avia 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.
Does the Flux L1 require calibration before each flight?
No. The Flux L1 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.
