gps etc

I noted when Atlantis came back, they included gps data into the mix, I
understand this is going to happen more and more soon.What I have never
really grasped about gps is how height information is obtained though.

On an alied subject, i see in the news group that they have discovered that
GPS receivers tend to lose lock when a large solar flare occurs. I cannot
say i'm surprised, as front end saturation probably occurs in the recievers.
I'd have thought this problem was an obvious one and was surprised to read
that its not been considered before.
