Processing data from over 1,500 Terrestrial AIS stations and Satellites worldwide we are one of the largest commercial AIS networks in Europe and one of the leading international providers of AIS vessel tracking services.

We store historical AIS data:

• from Jan 2009 to Dec 2011 at 1-hour time resolution (i.e. one ship position every one hour) - data for vessels with IMO number only i.e. vessels without IMO number but only MMSI number, do not present in this database

• since 2012 at 5-minute time resolution (i.e. one ship position every five minutes) - data for ALL vessels (with IMO or with MMSI number only)

• since October 2014 at maximum available resolution (i.e. all received position records) - data for ALL vessels (with IMO or with MMSI number only)

The cost of the AIS data depends on the number of position records, the data frequency and all extra processing that may be required.
