Get the AIS track of the last 24 hours for a 9-digit MMSI as JSON
Get the AIS track of the last 24 hours for a 9-digit MMSI as JSON: up to 1000 evenly sampled fixes with time, position and speed, ending at the newest fix. Sold only for vessels the AIS Fleet network currently observes; gaps between fixes mean no reception, never interpolation.
