At a certain moment, the geodetic coordinates of a GPS satellite are: longitude=150 degrees 40 minutes, latitude=45 degrees 30 minutes, ellipsoid height=20072000m;
the geodetic coordinates of an observer’s location are: longitude=121 degrees 35 minutes, latitude=20072000m = 25 degrees 45 minutes, ellipsoid height = 100m.
Please use the reference ellipsoid GRS80 to find:
(1) The distance between the observer and the GPS satellite. (Writing calculation process)
(2) The altitude and azimuth of GPS satellites. (Writing calculation process)
