Maurice, I agree with your logic about the delay, but just for the record the round trip delay for a 4,000 Km satellite is about 27 milliseconds, but it still keeps you below 150 milliseconds.

Ephemeris is used to describe the location of a satellite. There are several formats but one of the most commonly used is called a NORAD two element set. It is used to allow you to calculate where the satellite is at any given time by describing its orbit. In a typical stabilized satellite, the vehicle is compensating for drag and is either raising its altitude or remaining fairly constant. A vehicle that is descending in altitude raises questions because it appears to not be accounting for drag and thus no longer stabilized. One of the G* satellites appears to be decreasing in altitude and that is what prompted the question.
