Satellite Position Information

Recommended Posts

I've been reading the different entries on the "WAAS 36" posting with interest.


Where would the most informative material on GPS Satellites be found?

Isn't there a website or (s) somewhere that shows sat positions at any given time and information on them ? Can someone point me toward something like that?


I don't need highly technical specifics.....more like "Satellites for Dummies" ....gotta start somewhere.

The WAAS satellites are in geostationary orbits and don't move. The "regular" GPS satellites do move.


So it's not hard to calculate the positions of the WAAS satellites, but it is considerably more challenging to calculate those of the other GPS satellites. To do it properly you need the ephemeris data that the satellites themselves send.
