Ultra-low latency software for the UAS sector.
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.
Stop Annoying
the Neighbors
Our research prototype is a 100 gram palm-sized nano bicopter with toroidal propellers and semi solid-state batteries. Unnoticeable as close as 5 meters. Controlled from any Android/ATAK device — no briefcase required.
Quieter with more tech than the $40,000–$200,000 Black Hornet 4 — at a fraction of the cost.
// Two Configurations
One airframe. Two markets.
Consumer
Stop Annoying the Neighbors
Stabilized 360° 4K 100FPS video from a drone nobody can hear. Powered by LiquidForest ultra-low latency streaming, with GPS-based flight and intuitive touch or gamepad control.
- Stabilized 360° 4K 100FPS camera with ultra-low latency streaming
- GPS-based navigation and positioning
- Whisper-quiet flight — film without the drone soundtrack
- Fly with touch controls or any gamepad
Military / ISR
Undetectable Reconnaissance
Dual stabilized 360° 4K 100FPS + thermal payload with full GPS-denied autonomy. Flies undetectable on AI vision, maps structures with photogrammetry, and marks targets directly in ATAK.
- GPS-denied flight via AI vision — passive stereo camera optical flow
- Real-time environment mapping with onboard photogrammetry
- Autonomous target detection and auto-marking in ATAK
- Field deployable or air-dropped from larger aircraft to scout interiors
- Reusable or self-disposable mission profiles
- Auto-land at waypoint after autonomous mapping runs
// 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 collapse noise at the tip — 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 stabilized 360° 4K 100FPS 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 a whisper — quieter than rustling leaves. Paired with a bicopter configuration, the airframe stays palm-sized without sacrificing stability or control authority.
- Bicopter thrust-vectoring agility
- Whisper-class acoustic signature
- Stabilized 360° 4K 100FPS + thermal payload
