I believe I've made it clear my background is in the fields of Accounting and Computer Science, which is the reason I've not undertaken to argue orbital mechanics with you or anyone else. The basis of my remarks has been totally known, actual, observed, empirical, facts. Obviously, even the "experts" at Sirius don't know all there is to know about the subject. That said, it is pretty clear to me that your knowledge of the subject is superficial. >>> What problem?? If there is no problem why is Sirius spending hundreds of millions to launch another satellite and add additional repeaters? Surely, you don't believe the nonsense you spewed last week!!! Instead of running off at the mouth perhaps you should go read the actual reports of Sirius reception problems that are EVERYWHERE. >>> It appears that XM has a lot more "fill in" weak signal areas, than SIRI does. What we know is that XM has been able to decommission half of the repeaters it had in operation on day one after finding they aren't needed. Thus, XM's combined space/terrestrial system is functioning better than expected. Obviously, SIRI's isn't. The facts as I see them are as follows: 1. XM's combined space/terrestrial system is working better than expected, thus they been able to eliminate half their repeaters and still have excellent reception. 2. SIRI's combined space/terrestrial system is NOT working as well as expected, thus they are having to launch one additional satellite (after already launching 3 versus XM's 2) and at least double the number of repeaters they planned for. 3. Voluminous anecdotal reports exist concerning reception issues for Sirius while the number for XM is nominal, in spite of XM's larger number of subscribers. You can verify #3 for yourself by simply reading the various XM *AND* Sirius fansites. #1 and #2 should be self-evident to a rocket scientist such as you. I will entertain no further discussion of this subject with you until you present a cogent refutation of my 3 points above or until you accept them as correct.
