Two satellites are in circular equatorial orbits of different altitudes. Satellite A is in a geosynchronous orbit (one with the same period as the earth's rotation so that it "hovers" over the same spot on the equator). Satellite B has an orbit of radius rg = 26 000 km. Calculate the velocity which A appears to have to an observer fixed in B when the elevation angle is (a) O and (b) 90° The x-y axes are attached to B, whose antenna always points toward the center of the earth (-y-direction). B TA TB Answers: (a) 0=0: Vrel= (i İ + i j) km/h (b) 90° Vrel = (i i + i j) km/h
