Ok lets say we have a satellite going near the speed of light. The satellite is programmed to emit an e/m pulse once every second of the satellites lifetime. The speed of the satellite is an integer of a certain # of orbits/second. Lets say its at a speed of exactly 100 orbits/second (and say its a planet where 100 orbits/second is almost the speed of light). Lets also say there is a reciever picking up these signals on the ground and its programmed to aim the wave at that receiver. How much general time (since i didnt use specific numbers) would pass on earth before each pulse was recieved from an observer on earth. Also, what effect might this have on the e/m pulse? Would its frequency or wavelength change?
