I've been reading the threads in this forum about relative motion and time dilation and I would like to know if I am understanding things correctly. The atomic clocks aboard the GPS satellites are programmed with a "factory offset" (according to Wikipedia) of +7us/day for relative motion and -45us/day for gravitational time dilation for a total of -38us/day. So, if I were in the same earth orbit as the GPS satellite with two atomic clocks, and I want to send one of them to the earth's surface, how would I need to program it's clock so that it would be in sync with the one that remains with me on the satellite? My answer is +52us/day. Is this correct?
