Methodology

Research from a detection company

DroSonic OSINT is the research arm of DroSonic, a company building passive acoustic drone detection. We publish what we learn about the drone threat and the counter-UAS response because good detection starts with understanding the threat. We have a commercial interest in counter-UAS, and we say so; the analysis aims to be useful whether or not you ever buy from us.

Open sources only

We use only publicly available information: government and military statements, court and regulatory records, academic and technical papers, reputable news reporting, manufacturer documentation, and verifiable imagery or video. We do not use classified, controlled or leaked material, and we do not publish detail that would meaningfully help someone attack people or infrastructure.

• Primary sources first. Where a news report quotes an official statement, we link the statement.
• Every claim is cited inline, next to the sentence it supports, and listed again at the end of each report.
• Imagery is checked for location and date where possible before we rely on it.

How sure we are, stated every time

Every report, key judgment and logged incident carries a confidence level. It describes the strength of the evidence, not how likely or how serious an event is.

• High: confirmed by authorities, corroborated imagery, or several high-quality independent sources with no credible contradiction.
• Moderate: several independent sources agree, or an official acknowledgement exists, but key details remain unconfirmed.
• Low: a single source, an unverified claim, or reporting with significant gaps. Treat it as a lead, not a fact.

Where a number is contested, we show the competing figures and who produced them, rather than picking one.

Estimative words mean the same thing everywhere
