RE: [GPSstash] GPS Power-Up: Get Ready for New Sense of Place

How does he figure that having three signals per satellite will overcome
signal reflection? It seems like any time we have solid masses near or above
the GPS receiver, that there will be varying levels of error. I'm also
unclear about how the indoor reception is supposed to work. My limited
understanding would lead me to believe that it's one thing to get a cell
phone signal inside a building but quite another to receive a set of
coordinated signals that will accurately allow for calculation of a
location. The Wired author does not cite a source.
