Freefly Gremsy VIO F1: NDAA-Compliant EO/IR Payload With 4K Optical Zoom, Thermal Detection, and 2,400 m Ranging for Freefly Enterprise Platforms

The Gremsy VIO F1 is a compact, NDAA-compliant electro-optical and infrared payload configured by Freefly for direct Smart Dovetail integration on the Astro, Astro Max, and Alta X Gen2.

In 854 grams and a single 3-axis stabilized gimbal, it brings together three sensor systems that enterprise and government programs typically source and integrate separately: a 4K EO camera with 20× optical zoom and 240× combined maximum zoom, a FLIR Boson 640R thermal sensor delivering 640×512 imagery at 60 Hz with ≤50 mK thermal sensitivity, and a laser rangefinder accurate to 0.1–0.5 m at distances up to 2,400 m (1.5 miles).

Key Features and Benefits

  • FLIR Boson 640R thermal sensor: 640×512 @ 60 Hz with ≤50 mK sensitivity for day-to-night detection.
  • 4K EO camera: 8.51 MP 1/2.5-inch CMOS with 20× optical and 240× combined maximum zoom.
  • 2,400 m laser rangefinder: 0.1–0.5 m accuracy for standoff distance measurement at range.
  • 3-axis stabilized gimbal: 854 g payload maintains stable imaging through flight dynamics and wind.
  • Smart Dovetail pre-integrated: configured for Astro, Astro Max, and Alta X Gen2 by Freefly before shipment.
  • Simultaneous EO and thermal streams: PiP, Side-by-Side, Sync, and overlay display modes supported.
  • AI object detection: human and vehicle detection with auto zoom tracking on the live feed.
  • NDAA compliant and FCC approved: cleared for government and public safety program procurement.
  • GPS geotagging: location data embedded in EO and IR files for operational reporting and mapping.
  • 128 GB microSD included: pre-installed UHS-I card for onboard EO and IR capture.

Freefly configures and tests the VIO F1 before it ships — software settings, control protocols, and Smart Dovetail interface are pre-set for the Freefly platform, and the payload is ready for mount-and-go deployment on day one.

For fleet operators and solutions partners building out Freefly-based ISR, inspection, search and rescue, and public safety programs, the VIO F1 addresses the sensor integration question directly: a single NDAA-compliant payload that covers optical zoom, thermal detection, and precision ranging without requiring custom integration work on the aircraft.

Simultaneous EO and thermal streaming is supported with PiP, Side-by-Side, Sync, and overlay display modes, AI object detection for humans and vehicles runs on the live feed with auto zoom tracking, and GPS geotagging embeds location data in both EO and IR image files. On the Astro Max, the VIO F1 achieves 25–30 minutes of flight time per battery pair.

Note that Astro and Astro Max installations require a separately purchased isolator or Skyview Payload Mount — the Alta X Gen2 is compatible with its factory-included Smart Dovetail isolator mount.

Pre-Integrated Sensor Capability for Fleet-Level Freefly Deployments

For solutions partners and fleet operators building Freefly-based sensor programs, the integration overhead of a multi-sensor EO/IR payload is typically the friction point — not the capability itself. The VIO F1 eliminates that friction by arriving pre-configured for the Freefly platform. Freefly sets the software, control protocols, and communication interface before shipment, so the payload mounts to the Smart Dovetail and operates without additional setup.

The 240× combined zoom closes the standoff distance gap for surveillance and inspection — keeping the aircraft well clear of the subject while maintaining the resolution needed for positive identification or structural detail. The FLIR Boson 640R's 60 Hz frame rate at 640×512 with ≤50 mK sensitivity supports full-darkness and smoke-penetrating thermal detection, and the 2,400 m rangefinder adds precise distance data to both EO and IR workflows.

For fleet operators sourcing multiple VIO F1 units across a Freefly program, the pre-integrated configuration means every unit deploys identically — no per-unit setup variation, no integration inconsistency across the fleet.

What is the Gremsy VIO F1 and what Freefly platforms does it support?

The Gremsy VIO F1 is a lightweight, NDAA-compliant electro-optical and infrared payload configured by Freefly for direct Smart Dovetail integration on the Freefly Astro, Astro Max, and Alta X Gen2.

It combines a 4K EO camera with 20× optical zoom and 240× combined maximum zoom, a FLIR Boson 640R thermal sensor delivering 640×512 imagery at 60 Hz with ≤50 mK thermal sensitivity, and a laser rangefinder accurate to 0.1–0.5 m at up to 2,400 m — all in a single 854-gram, 3-axis stabilized gimbal that ships pre-configured with the software and communication settings needed for immediate Freefly platform deployment.

Does the VIO F1 require additional hardware on the Astro or Astro Max?

Yes. The Astro and Astro Max require a separately purchased isolator in addition to the Smart Dovetail mount included with the VIO F1. For the Astro, compatible options are the Astro Isolator with 30A isolator balls or the Skyview Payload Mount.

For the Astro Max, compatible options are the Astro Isolator with 30A isolator balls, the Astro Max 30A Isolator, or the Skyview Payload Mount. The Alta X Gen2 requires no additional hardware — it is compatible with the factory-included Smart Dovetail 30A isolator mount. Dronefly can confirm the correct isolator for your specific aircraft configuration before purchase.

How does the EO and thermal simultaneous streaming work in the field?

Both the 4K EO camera and the FLIR Boson 640R thermal sensor stream simultaneously and are displayed through the payload settings interface in one of six modes: EO only, IR only, EO/IR overlay, IR/EO overlay, Picture-in-Picture, Sync, or Side-by-Side.

This allows the operator to select the display configuration that best fits the mission — PiP for maintaining spatial context during thermal target tracking, Side-by-Side for simultaneous full-resolution review of both feeds, or overlay modes for blended situational awareness.

AI object detection for humans and vehicles runs on the live feed with auto zoom tracking that locks onto selected targets dynamically across either sensor stream.

What is the laser rangefinder used for and how does it integrate with the EO/IR workflow?

The integrated laser rangefinder measures distances from 0 to 2,400 m at 1 Hz and 0 to 1,200 m at 10 Hz with an accuracy of 0.1–0.5 m. In EO/IR operational workflows it provides precise distance data for subject or structure identification — enabling operators to determine exact standoff distance, support targeting workflows, and generate location-accurate inspection documentation.

Combined with GPS geotagging in both EO and IR image files, rangefinder data supports precise coordinate reporting for ISR, public safety, and infrastructure inspection deliverables without requiring a separate ranging instrument.

Is the VIO F1 thermal camera fully radiometric and can the IR data be analyzed post-flight?

The VIO F1 uses a FLIR Boson 640R sensor — the radiometric variant of the Boson platform. IR JPEG images are captured to the onboard microSD card with temperature data included.

At the time of this listing, the IR output does not yet include full FLIR-style embedded radiometric metadata in the RJPEG format — the files are standard JPEGs with temperature information rather than full per-pixel radiometric data. Freefly notes this as a planned capability update.

Operators whose workflows require full per-pixel radiometric metadata should confirm current firmware status with Dronefly before purchasing.

Is there anything specific about purchasing the VIO F1 I should know before ordering?

Yes. The Gremsy VIO F1 is export controlled under ECCN 6A003.b.4.b and requires a signed disclosure before it can ship to eligible buyers. Dronefly will provide the required documentation as part of the order process.

Contact Dronefly directly to initiate your order and complete the disclosure before shipment is arranged.
