It was my understanding that WAAS used a terrestrial land based signal that was received by WAAS capable receivers. But in my reading from Wikipedia and a web site it appears a WAAS station (Can't remember the correct term) uplinks corrections to the GPS satellite. Is that how WAAS is used?
Another question: I typed in the GPS frequency of 1575.42 into my scanner connected to an outside antenna, but didn't hear anything. I guess either that is due to the signal being so weak or the wrong modulation which I was using NFM. Maybe it's like DSS? So you can't hear the signal?
