Which of the following are provided by satellite tracking programs?
Maps showing the real-time position of the satellite track over Earth
The time, azimuth, and elevation of the start, maximum altitude, and end of a pass
The apparent frequency of the satellite transmission, including effects of Doppler shift
All these choices are correct✓پاسخ درست
توضیح
All three are standard outputs of tracking software, because they all follow from propagating the orbit against the operator's location: the ground track map, the pass predictions with times and look angles, and the Doppler-corrected frequencies. There is no reason a program computing the geometry could not report all of them.
