ANDRE' DRESS: That's, Sandy, that's a good question. The difference is primarily in their mission. Okay, the GOES and the POES spacecraft do the same things in that they take pictures and take weather data, okay, but what we're really looking at is the different perspective of those two satellites. Now, the POES satellite is launched into what we call a low-Earth orbiting mission, okay, and so it orbits the Earth about 900 kilometers. And so it orbits the Earth about every 100 minutes, it revolves around the Earth, so every day, it orbits the Earth about 14, 15 times.
