They have, actually. It's very complex. The analogy I've used is that what we're doing here is detecting radio frequency signals from ships. The International Maritime Organization, many years ago, mandated that every ship above a certain size has to transmit a signal saying who it is, where it is, what the cargo is, where it's going, which port it's from, and so on. It has to send the information out. What that did was provide collision avoidance. So ships, if they're in the dark or in the fog, know who's around them, because they're sending signals to each other. That's an easy system to define, and it has a very short range of 25 nautical miles.
What COM DEV said was that if we can detect those signals from space, maybe we can provide a global picture of all the ship traffic around the world. The first problem with that is actually detecting a signal that was never intended to be received in space. For a company like COM DEV, that is easy. We are the world leaders in gathering radio frequency information from space. We are far and away the world leaders. Eighty per cent of all commercial communications satellites have our equipment on board. That's what we do.
The second challenge is the one you refer to, and it's a real problem, because these transmissions are very random. If I'm in a small cell with you and I send a random signal and you send a signal--we send a signal--they don't collide with each other. It's a bit like if I'm on a stage of a theatre and there are two people in the audience talking to each other. I can hear what they say, because there are just two signals. Now imagine the same theatre and you're on the stage and there are 10,000 people talking to each other. It just sounds like a mess. You can't understand anything.
What we've done is have a group of about 15 Ph.D. engineers, working for three years with highly advanced supercomputers, figure out how to use radio frequency information to extract that data you need, and this solution we have is far and away the most advanced solution in the world today.
