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.

US Raises Privacy Concerns Around AIS

Posted by Peggy Browning on Sep 29, 2015 11:31:31 AM

A recent lawsuit filed in the U.S. by the Electronic Privacy Information Center against the U.S. Coast Guard and Department of Homeland Security has sparked debate over the intrusiveness of AIS into personal privacy. The Nationwide Automatic Identification System used by the USCG and DHS collects, integrates and analyses information concerning vessels operation in waters subject to US jurisdiction. The complaints arise around the idea that AIS goes far beyond the collision avoidance mandate it was put in place for and instead collects personal information about boaters that is then shared between a variety of parties outside of just the Coast Guard.

Catching Up with Deadliest Catch

Posted by Nicole Schill on Aug 13, 2015 10:30:06 AM

Summers in Canada conjure up images of sitting out on the dock of the bay, fishing pole cast into a serene lake while off in the distance a loon lets out its distinct call.

Over on the Discovery Channel, they are reminding us that all sorts of fishing activity is happening in some not so serene places. Deadliest Catch (airing Tuesday nights at 10 p.m.) follows the crews of fishing vessels in the Bering Sea during the Alaskan crab seasons. After a couple episodes you will quickly discover where the show gets its title when you see the high level of risk for the crew aboard these boats. Huge rogue waves and frigid waters combined with massive industrial fishing equipment being hurled around at breakneck speed makes for some extreme TV.

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!!

Vessel Monitoring for Whale Ship Strike Risk

Posted by Nicole Schill on May 6, 2015 9:08:00 AM

Many species of whales and dolphins are vulnerable to collisions with vessels that can sustain serious damage to the ship and also injure or kill the animal. There is no universal solution to the problem of ship strikes but clearly the most effective way to reduce collision risk is to keep whales and ships apart. And that's exactly what the National Oceanic and Atmospheric Administration (NOAA) is trying to do.

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.

Hacking Into AIS

Posted by Peggy Browning on Oct 16, 2013 2:26:00 PM

There has been some publicity lately around the notion of being able to ‘hack AIS’.  I think it’s critically important to understand a few technical points about AIS before spending the time discussing such an idea.

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.
