Re: Can someone please explain
For some high precision receivers, they do listen for a signal outside of the GPS band. But they do so because they are using GPS correction services that pay satellite companies like LightSquared to broadcast them. So they are perfectly legitimate, legal and licensed. These receivers are heavily affected since they were listening for a weak satellite signal and now get a strong terrestrial one.
For other GPS receivers, they do not listen in the LS spectrum. However, because brickwall filters don't exist in real-life, at the power level that LS is broadcasting at, these GPS receivers are forced to hear the unwanted LS signal and causing interference.
