? Should be a day job to find out where they were served last. Some critical data is not going our and that sucks for those that think they want to help or are out flying around. Basic data and its not out on public view, seems like poor cya stuff.
The first hit on Google
gave the andwer: full global coverage like I had read before on this very same forum
Here is the text from http://www.orbcomm.com/services-ais.htm
Automatic Identification System (AIS) is a shipboard broadcast system that transmits a vessel's identification, position and other critical data that can be used to assist in navigation
and improve maritime safety
terrestrial-based AIS systems provide only limited coverage nearby shorelines and are not able to provide global open ocean coverage. ORBCOMM overcomes many of these issues thanks to a fully satellite-based AIS data service
, which is able to monitor
maritime vessels well beyond coastal regions in a cost-effective and timely fashion.
ORBCOMM was the first commercial satellite
network with AIS Data Service
In 2008, ORBCOMM launched low-earth orbit satellites specially equipped with the capability to collect AIS data, and has plans to include these capabilities on all future satellites for ongoing support of global maritime safety
ORBCOMM has recently launched two dedicated AIS microsatellites, one in an equatorial orbit and the other in a polar orbit, which allows ORBCOMM to provide complete global AIS coverage. ORBCOMM will be launching 17 additional AIS-equipped next generation satellites beginning in late 2013.
Annual subscription service agreements and user applications for global, regional and filtered satellite
AIS data are available to both qualified government
customers. Simply contact ORBCOMM to gain access to global AIS vessel data.
