Blazing a Path to Continuous Real-Time Global Ship Tracking

Posted by Graham Stickler on Jul 12, 2016 9:54:05 AM

We’re very excited at exactEarth as the countdown to the launch of our 2nd generation satellite constellation, exactViewRT powered by Harris, draws ever closer. Our maritime-focused payloads have now been delivered for installation on the first batch of the Iridium Next satellites, and we eagerly await confirmation of the first launch date later this summer.

Should I Track Global Fishing Activity with VMS or AIS?

Posted by Nicole Schill on Aug 4, 2015 2:12:53 PM

 

The battle of the fishing boat monitoring acronyms rears its head yet again. Here at exactEarth we're asked often about how AIS compares to VMS and why to use one system over the other. We believe that although the systems are different, they can be quite complementary.

As the global illegal fishing crisis intensifies, it's important to look for the best tracking and monitoring system possible.

Satellite AIS Just Got Real

Posted by Nicole Schill on Jul 6, 2015 1:36:00 PM


In case you missed our big announcement, we wanted to fill you in.

exactEarth and Harris Corporation have partnered up to bring to you real-time Satellite AIS. That's right, real-time global ship tracking from space will soon be a reality. Through the new partnership, we're able to hitch a ride on 58 hosted payloads of the Iridium NEXT constellation.

These satellites are networked together with crosslinks and are in constant communication with multiple ground stations. This means you receive AIS data in real time!

We're all about taking giant strides forward to expand our services and the system that powers them. That's why we're also really excited about the 2 planned satellite launches in the fall of 2015, including an equatorial satellite that will significantly lower the current revisit times.

Satellite AIS is changing forever - Take a look at our latest infographic to learn more about our present system with a glimpse into the future as well with exactView RT!!

The Filthy Facts About Shipping Pollution

Posted by Nicole Schill on May 19, 2015 1:26:16 PM


Our oceans are regularly victim to pollution caused by oil slicks and the dumping of rubbish resulting from accidents and illegal activities. Nearly half of the pollution at sea is caused by ships’ accidental or deliberate discharge of crude oil and other refined products.

Combining these traditional pollutants with the atmospheric effects of shipping emissions, vessels have a globally substantial impact on our ocean environment.

What role can Satellite AIS play in monitoring these pollution incidents or even better, preventing them from happening?

Buoyed by Innovation

Posted by Nicole Schill on Aug 6, 2014 2:52:00 PM

Recently we announced two new product offerings into the exactEarth family- exactEarth ShipView™ and exactAIS Density Maps™. These new tools were built so that customers could see more and do more with our amazing exactAIS® data service.

ShipView was designed entirely with you in mind as great attention from our development team was paid to ensure the new platform performed at an exceptional level. As an eventual replacement to the existing exactAIS Viewer, we kept all the same features that you know and love but also added in tons of handy new tools like the ability to add external layers and download data. Customise away as the ShipView platform accepts map layers or base maps from OGC WMS or Esri Map, Feature, or Tiled Map Services.

Spoofing AIS- The Debate Continues

Posted by Peggy Browning on Mar 19, 2014 2:17:00 PM

The debate around the idea of hacking into AIS has been circling for some time. There are now claims made by data providers in the industry trying to dispel the rumours around being able to easily spoof AIS messages.

Data streaming in GIS

Posted by Graham Stickler on Feb 10, 2014 10:59:00 AM

We are delighted at exactEarth to see Esri’s efforts to advance the management and use of streaming data feeds into the GIS environment, which traditionally has been dominated by static maps.  As a major supplier of near real-time geospatial data for maritime vessels, here at exactEarth we are committed to interoperability of our data with all platforms and as an Esri Business Partner we were closely involved in the ArcGIS® 10.2 GeoEvent™ Processor for Server beta program, working with Esri to ensure our exactAIS® global ship data can be ingested and processed easily by ArcGIS® 10.2 GeoEvent™ Processor for Server.

Taking Satellite AIS to the next level

Posted by Peggy Browning on Jun 5, 2013 1:12:00 PM

There has been some discussion to what makes a great Satellite AIS system so I wanted to throw in my opinion on the topic.  AIS is designed for collision avoidance for ships, an undisputed fact.  But once we start collecting AIS signals from space from all those thousands of ships, means we’ll have LOTS of slot overlap and signals competing with each other.  The two methodologies for processing AIS signals are On-board processing (OBP) which can not separate AIS messages that collide in a slot and Spectrum Decollision Processing (SDP) which can.  Research has shown that OBP just can not process the signals like SDP, especially in dense shipping areas with more than 1,000 ships in the vicinity.  With SDP, Satellite AIS systems achieve better First Pass Detection rates, every time, maximizing the number of ships detected in every satellite pass.

Creating Open Ocean VTS

Posted by Peggy Browning on Feb 20, 2013 1:32:00 PM

exactEarth recently signed up to assist in a new vessel routing program run by the European Union.  The MONALISA project aims at giving a concrete contribution to the efficient, safe and environmentally friendly maritime transport.  The initial focus is on the major navigational areas in Swedish and Finnish waters in the Baltic Sea which will contribute to improving overall safety and optimization of ship routes.

Sharing Does Not Always Mean Caring

Posted by Peggy Browning on Nov 22, 2012 11:04:00 AM

I recently attended two symposiums (USEUCOM and C-Sigma - TEXAS V) where the subject of "Data Sharing" was discussed.  As I looked around the room, it struck me that for different groups, the term “data sharing” conjures up very different feelings.  From an Administration's perspective, Data Sharing means equal access between partners in order to further collaboration and advance the cause whether that cause is security, defense, ecological, meteorological, etc.  But from the Data Provider’s perspective Data Sharing equals Bankruptcy!
