Ultra-low latency software for the UAS sector.
Beyond our own airframes, StealthSky and LiquidForest deliver consulting and custom ultra-low latency software for the UAS/UAV industry — from micro and nano platforms to larger Jetson-powered systems. Everything runs on GPU, especially in GPS-denied environments.
Streaming Stacks
Ultra-low latency video pipelines for any UAS platform.
Jetson Platforms
GPU-accelerated autonomy on NVIDIA Jetson hardware.
GPS-Denied Nav
AI vision, optical flow, and passive stereo navigation.
Mapping & ISR
Photogrammetry and real-time situational awareness tooling.
The World's
Quietest Drone
A palm-sized nano bicopter with toroidal propellers and semi solid-state batteries. Under 20dB at 30 meters. Controlled from any ATAK device — no briefcase required.
Competing with the $40,000–$200,000 Black Hornet 4 — at a fraction of the cost and footprint.
// ATAK Native
The briefcase is dead.
The Black Hornet needs a dedicated briefcase controller. StealthSky flies from the ATAK device already in your kit — touch controls or a gamepad, your choice. Autonomous missions run end-to-end: scout a structure, map it with photogrammetry, auto-mark targets in ATAK, then land at a waypoint. No pilot input required.
While the palm-sized Black Hornet 4 can cost upwards of $40,000 – $200,000 USD per unit and requires a large briefcase-style controller to pilot, StealthSky is working on a nano bicopter design featuring toroidal propellers and semi solid-state batteries which can be flown by any ATAK device with touch controls or a gamepad (controller).
// Core Technology
Engineered for silence.
Built for the field.
Toroidal Propulsion
Ring-shaped toroidal propellers slash acoustic signature below 20dB at 30 meters — quieter than a whisper, invisible to the ear.
Semi Solid-State Batteries
Next-generation semi solid-state cells deliver extended endurance in a palm-sized airframe without the weight penalty.
Ultra-Low Latency Streaming
LiquidForest streaming technology pushes 4K and thermal video with near-zero latency to any ATAK device.
Fly From Anything
No briefcase controller. Pilot from any ATAK device with touch controls or a standard gamepad.
// Propulsion
Toroidal propellers. Whisper-class acoustics.
Conventional rotors announce themselves. Our toroidal ring propellers recirculate tip vortices, collapsing the acoustic signature to below 20 decibels at 30 meters — quieter than rustling leaves. Paired with a bicopter configuration, the airframe stays palm-sized without sacrificing stability or control authority.
- Bicopter thrust-vectoring agility
- Sub-20dB acoustic signature @ 30m
- Stabilized 4K + thermal payload
// Two Configurations
One airframe. Two missions.
Consumer
