meaconing.com is a standalone educational site that explains **meaconing**, the replay of genuine GNSS signals, for readers with no prior knowledge. Its sources are listed on every page, and it discloses that it features a product, Navion Terra by Ultrakinematic.

## What this site is

meaconing.com explains one attack in depth: how genuine satellite navigation signals are captured and replayed, why replay attacks pass authentication and integrity checks, how crewed aircraft cope, and how drones can stay on course. It is written for beginners, drone operators, and aviation and security professionals.

## Sister site

[gnssdenial.com](https://gnssdenial.com/) covers all GNSS threats broadly, with full data and an incident timeline. The two sites use different text on purpose: this one goes deep on a single attack, the other gives the wide overview.

## How facts are sourced

- Figures are attributed to the report they come from, with the year, for example OPSGROUP 2024, Windward 2025 and RUSI 2023.
- Figures about GNSS interference in general are labelled as such and are not presented as meaconing statistics.
- Illustrative scenarios, such as the second-by-second incident, are labelled as illustrative.
- The full list of sources is on the [home page](https://meaconing.com/#h-src) and at the foot of each guide.

## How pages are kept current

Every page shows a "last reviewed" date. When figures change, the page's date is updated together with its structured data, sitemap entry and the Markdown copy for AI assistants. Corrections are welcome: see the contact below.

## Disclosure

This site features **Navion Terra**, a GNSS-independent navigation system made by **Ultrakinematic**, and links to Ultrakinematic. Sections about Navion Terra are vendor information. The explanations of meaconing, spoofing, OSNMA and detection are written to stand on their own, with sources, and do not depend on the product.
