ANI Linux
ANI Linux (Advanced Nautical Information Linux) is a highly specialized operating system tailored for use on ships, yachts, and maritime vessels. It is designed to provide a stable, reliable platform for electronic charting, navigation, and critical vessel monitoring, often replacing proprietary marine electronics systems.

[edit | edit source]ANI Linux is built on a hardened **Debian Stable** base, chosen for its long-term reliability in harsh, remote environments. It typically uses the **Xfce** desktop, which is customized for high-contrast visibility on low-light or sun-glare prone screens.
- Charting and GPS Integration: The distribution is pre-loaded with open-source charting software, most notably **OpenCPN**, fully integrated with drivers for various GPS receivers, depth sounders, and marine radar systems. Custom kernel modules ensure reliable handling of serial data from NMEA 0183 and NMEA 2000 devices.
- AIS Monitoring: ANI Linux includes dedicated tools and daemons for receiving and processing AIS (Automatic Identification System) data, allowing the operator to track nearby vessels in real-time on the digital charts, a critical safety feature at sea.
- Offline Functionality: Given the unreliability of satellite internet at sea, the entire system is designed to function robustly offline. All charts, weather routing models, and logbooks are stored locally, with custom utilities for synchronized updates when a connection is available.
- Ruggedization: The system is often deployed with a read-only root filesystem to prevent file corruption from sudden power loss or vibration, common issues in a marine environment.
ANI Linux is favored by long-distance cruisers and research vessels for its cost-effectiveness, customization, and open-source auditability.
