*Ephemeris and Wonky Satellite* I figured it out! The satellite is probably being moved from one orbit to another. They do that as part of the process of getting all the ducks in a row ready to receive and transmit signals. They launch them into lower orbits, then let them precess to the correct orbit, then raise them.

It is probably not a wonky or ephemeral satellite. No worries! All satellites are humming beautifully. Voice quality is great. Let's roll it out.

Ron, By the way, what is the deal with the large short interest in this one? I posted it earlier but got no response. Is this a concern for any on this thread? Also what are the dates of any future launches and how many are expected? I know that GSTRF has had their problems in the past with these. Also, is there any big news expected in the short term? So many questions, so little time....

I don't follow or even glance at short interest. I have no interest in it and am unconcerned. Dates are monthly, more or less, from now on. Another half a dozen launches will complete the system, almost [depending on how many prang]. You never know if there'll be big news or not. Maybe ICO will fold the tent. Maybe Constellation Communications [nee ECCO] will sell out to Globalstar since they seem in trouble. Odyssey gave up. Teledesic is dodgy.

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.
