Data Collection

AIS Fleet is a community-driven platform that collects Automatic Identification System (AIS) data from contributing stations. The data we collect includes:

Vessel Data

• AIS Vessel Information: Data about vessels within range of contributing stations, including MMSI, vessel name, position (latitude/longitude), course, speed, heading, and other standard AIS transmission data
• Source Attribution: MMSI and UUID of the reporting station/device that contributed the data
• Timestamp: Time when the data was received and reported

Query Data

When users or applications query our API for nearby vessel information:

• Position Data: The geographic position (latitude/longitude) is required to perform proximity-based vessel queries

Data Sources

All vessel data is contributed by local AIS receiving stations operated by community members. These stations report information about vessels within their reception range. AIS transmissions are public maritime safety broadcasts, and no personally identifiable information beyond what is broadcast by vessels themselves is collected.

Data Usage

The collected data is used to:

• Provide a real-time global view of vessel positions
• Enable community members to query nearby vessel information
• Generate station coverage and reporting statistics
• Support maritime situational awareness applications

Data Retention

Vessel position data is stored to maintain historical vessel tracks and enable analytics. Station reporting metadata (MMSI, UUID, timestamps) is retained to track data provenance and station activity.

Data Sharing

AIS data collected by the platform is available to all users through our API and map interface. This data represents publicly broadcast AIS transmissions and is shared in accordance with international maritime safety standards.
