Fifth, our airlines will achieve significant savings in terms of both equipment and operating costs, as they shift to satellite-based navigation. For aviation applications, we need the accuracy WAAS will provide. I know hikers in Colorado use it. Recreational boaters use it. Ships navigating on high seas use it, and they get to their destination more efficiently and with less costly.
Emergency vehicles use it.
If you want to go to Disney World, it tells you to turn left at the interstate. It might even save a few arguments between spouses on where to turn when you're lost. Beyond, aviation, long-term the benefits to the public of WAAS are as far as the imagination can stretch. For example, the people tracking hurricane Erin right now, if they had WAAS, they could measure wind direction and velocity down to a few meters, which would better help forecast storm intensity and where the hurricane may hit. Or buses may use it in the future to tell customers as they wait at a stop that the bus is seven blocks away, and will be there in two minutes.
