Gremsy Vio G1 for SkyScout Series

Gremsy VIO G1: Radiometric Thermal, 240× Zoom, & 2,400m Ranging

The Gremsy VIO G1 brings radiometric thermal imaging, long-range optical zoom, and precision laser ranging to the SkyScout Series in a single NDAA-compliant, pre-integrated payload.

At 854 grams, it consolidates what most operators source separately: a 4K EO camera with 20× optical and 240× combined maximum zoom, a Thermal Core 640 Radiometric sensor at 640×512 and 30 Hz, and a laser rangefinder that reaches 2,400 m with sub-meter accuracy.

It arrives configured for the SkyScout Series and ready to fly without additional setup.

Payload Highlights

• Thermal Core 640 Radiometric sensor: 640×512 at 30 Hz with ≤50 mK sensitivity and live radiometric temperature overlay
• Wide scene temperature range: -20°C to 150°C (high gain) and 0°C to 550°C (low gain)
• 19 mm fixed focus athermal lens optimized for longer-range thermal observation at standoff
• 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
• 3-axis stabilized gimbal at 854 g for stable imaging through flight dynamics and wind
• Simultaneous EO and thermal streams: PiP, Side-by-Side, Sync, and overlay display modes
• AI object detection for humans and vehicles with live auto zoom tracking
• NDAA compliant and FCC approved for government and public safety procurement
• GPS geotagging in both EO and IR files for mapping and reporting workflows
• Includes 128 GB microSD, lens cover, thermal focus tool, and travel case

Government, public safety, and industrial operators who need a sensor stack that covers optical zoom, thermal detection, and precision ranging will find everything in one mount-ready package that clears NDAA and FCC requirements from day one.

EO Camera

Twenty times optical zoom combined with 30× super-resolution gives the G1 a 240× maximum. At that range, operators can positively identify subjects and resolve structural detail while keeping the aircraft at a safe operating distance.

Thermal Imaging

The Thermal Core 640 Radiometric sensor goes beyond visual heat mapping. Every pixel carries actual temperature data, overlaid on the live video feed in real time — no post-processing needed. The operating range extends from -20°C to 150°C in high gain and up to 550°C in low gain, covering everything from environmental surveys to high-temperature industrial inspections.

Thermal Lens

The 19 mm fixed focus athermal lens holds consistent focus regardless of ambient temperature shifts. The narrower field of view suits missions where thermal observation at longer standoff distances is the priority.

AI Detection and Display

On-board AI identifies humans and vehicles on the live feed and locks auto zoom tracking onto selected targets. EO and thermal streams run simultaneously with operator-selectable display modes: PiP, Side-by-Side, Sync, and full EO/IR overlay.

What the G1 Replaces

Running a separate EO camera, thermal sensor, and rangefinder means three mounting points, three calibration workflows, and three integration variables per aircraft.

The G1 puts all three on one gimbal, under one interface, through one mount connection the SkyScout Series already supports. Dronefly configures and verifies each unit before it ships, so there is no per-unit setup and no variation across a fleet.

Compatibility and System Integration

• SkyScout Series: compatible with SkyScout Series payload mount interface; confirm variant requirements prior to ordering
• ArduPilot and PX4: supported autopilot protocols
• UART and Ethernet: supported control interfaces for payload communication and configuration
• microSD up to 128 GB: onboard storage for simultaneous EO and IR capture

Applications and Use Cases

• Industrial diagnostics and asset security: live radiometric overlay and wide temperature range pinpoint heat anomalies across large facility footprints
• Critical infrastructure inspection: 2,400 m rangefinder and 240× zoom resolve fine structural detail at standoff
• ISR and surveillance: long-range zoom and thermal detection support sustained situational awareness
• Search and rescue: thermal sensor detects heat signatures through darkness, smoke, and dense cover
• Public safety operations: AI detection and auto zoom tracking support monitoring from altitude
• Environmental monitoring: simultaneous EO and thermal capture suits vegetation and wildlife survey workflows
• Night operations: 640×512 thermal at 30 Hz with ≤50 mK sensitivity covers full-darkness mission profiles

For Dronefly customers building out SkyScout Series programs around inspection, diagnostics, and compliance-sensitive ISR, the VIO G1 is the thermal payload that checks every box.
