Ancile

Product

Passive detection, localization, and classification of small drones.

Ancile's passive sUAS product is a software stack built around multi-modal sensor fusion on COTS hardware — covert, persistent awareness at the edge, developed with a Tier-1 defense partner and scheduled for field testing in Q3 FY26.

How it works

Asynchronous sensor inputs, correlated into usable tracks.

The software correlates asynchronous sensor inputs into targeting-grade tracks while staying low-observable and power-conscious. It is built for rapid setup and practical integration into the systems a team already fields.

  • Passive LP/OP operation with no active emissions to detect or jam
  • Multi-modal sensor fusion for detection, localization, and classification
  • COTS hardware baseline for affordability, sustainment, and rapid fielding
  • Sequenced sensor activation to cut power draw and extend endurance in austere sites
  • Modular software architecture ready for future sensor and effector integrations

System Architecture

A modular fusion platform — not a fixed sensor stack.

The product is the fusion software. Passive sensors are modular inputs — RF, EO/IR, and acoustic today, extensible tomorrow — and the tracks it produces hand off to the systems you already operate.

Teaming Model

Responsibilities split cleanly across the team.

Ancile owns the software and the data; our partners own the hardware and the flight testing. Each interface is defined so the system matures without ambiguity over who delivers what.

Our scope

Ancile — Software Package

Fusion software, detection and classification models, data architecture, and the integration workflows that turn raw sensor feeds into usable tracks.

Fusion softwareDetection modelsData architectureIntegration

Tier-1 Defense Partner — Hardware

Hardware design, power architecture, full rate manufacturing, and platform interfaces for deployable node configurations.

R&D & Flight-Test Partner

Flight testing, environmental data collection, and validation that accelerate prototype maturity and transition.

Built for the field, not the demo.

The product is shaped by deployment constraints — low signature, limited power, contested spectrum, and disconnected sites — so it performs where it is actually used, then transitions cleanly into a partner program.
