How Standard AIS works

Spire’s Standard AIS provides unrivalled vessel tracking through our ever-expanding set of data sources.

Spire Maritime’s Standard Satellite AIS is powered by our Low Earth Multi-Use Receiver (LEMUR) satellite constellation. This constellation, consisting of hosted VHF maritime receiver payloads, collects global radio frequency data in near-real-time from nanosatellites equipped with multiple sensors. The data is then delivered with low latency through the world’s largest network of ground receiving stations dedicated to small satellites. This satellite data forms the foundation of our service. We fuse this satellite data with information from various additional sources, such as terrestrial AIS stations, to provide a comprehensive view of maritime activities.

This approach, combined with our globally distributed satellite operations and IT support teams, ensures a reliable and continuous service.

With the largest team of Satellite AIS technology experts and specialists in the world, Spire Maritime is committed to delivering world-class capabilities to our customers.
