They can, actually. They're mandated to carry those things. They're signatories to the IMO, which requires them to do it. With respect to information and tracking, if a ship is transmitting its signal as it's supposed to, and then it turns it off, interestingly enough it becomes a target of interest. We can track its history across the world. It went from Sydney to the port of London and on to Brazil, but as it approached Canadian waters it switched off its transmitter.
Our software is able to detect all sorts of interesting things—they're called watchdogs. If it turns it off, we flag it up. If it's a Spanish fishing vessel that comes within 300 nautical miles of our shore, we want to know. If there are two ships that come together at sea and stay together, that's unusual, and we want to know what's going on. If two ships are sailing in areas in which they're not supposed to sail too close together, or if they're sailing in an area where whales are supposed to be breeding, or if they're drift-netting in the wrong part of the ocean, the software flags it up for us. So the software enables you to detect people doing strange things. We also have some very clever tools to figure out activities that may be of interest to our authorities, over and above the signal itself, but I can't talk about this much.
