01 / THE MISSIONBUILT FOR WHAT COMES NEXT
The battlefield changes.
Our thinking must
move faster.
New threats expose old assumptions. Smaller systems. Faster adaptation. Less warning.
Sinthos is building a defense technology company around this reality. We start with perception: helping people and systems understand what is approaching, even when conventional signals are absent.
Our first development program02 / FIRST PROGRAMPASSIVE ACOUSTIC INTELLIGENCE
A new layer
of awareness.
IN DEVELOPMENT
When a drone’s control link leaves the radio spectrum, a familiar detection channel disappears. The aircraft still moves air.
Our first program explores how passive acoustics and machine learning can turn that sound into useful warning.
ACOUSTIC FIELDCONCEPT STUDY
SOUND IS A PHYSICAL SIGNATURE.
THE APPROACH
Capture the mechanical sound of flight. Investigate microphone arrays that listen without relying on a drone’s radio transmissions.
PASSIVE SENSING / SIGNAL ACQUISITIONIllustration of the intended sensing workflow. Algorithms and hardware are in development.
DESIGN INTENT / 01
Passive by nature.
Sense the sound an aircraft produces, without transmitting a detection signal.
DESIGN INTENT / 02
Intelligence at the edge.
Develop compact models with a path to local processing and useful alerts.
DESIGN INTENT / 03
Part of a larger picture.
Build toward integration with optical sensors and existing awareness systems.
03 / DEVELOPMENTEVIDENCE BEFORE ASSUMPTION
Capability is earned
in the field.
A disciplined path from public data to representative conditions. Each stage must show what works, what fails, and what comes next.
Challenge the model.
Test across microphones, environments, and aircraft. Measure missed events and false alerts, alongside processing requirements.
SOFTWARE & EVALUATIONValidate in the real world.
Work toward controlled trials with representative FPVs, synchronized recordings, and independently measured flight conditions.
HARDWARE & FIELD TRIALSRESEARCH CONTEXTWhy this problem matters
Public defense requirements recognize the challenge of fibre-optic-controlled drones and the need for complementary sensing. These sources inform the program; they do not establish Sinthos performance or an affiliation.

PERCEPTION IS THE BEGINNING.
Sinthos is being built for the long term. Our first program begins with acoustic awareness. Our ambition is a defense technology company that brings sensing, software, and hardware together to meet evolving threats.
05 / WORK WITH USSINTHOS INC.
The next advantage
starts with a
conversation.
We’re looking to speak with defense integrators, acoustic researchers, and partners who can help test the technology in representative conditions.
