Annual Status Report (July 1,2007 -June 30,2008) 
Dear Ms. Domenici: 
Pursuant to Section 25.144(c) of the Commission’s Rules, XM Radio Inc. (“XM Radio”) 
hereby submits its annual status report for its satellite Digital Audio Radio Service (“SDARS”) 
system. XM Radio currently operates a fleet of four SDARS spacecraft. XM-3 (call sign S26 17) 
and XM-4 (call sign S2616) provide primary service from the nominal 85” W.L. and 115” W.L. 
orbital locations, respectively. XM- 1 (call sign S2 1 1 8) and XM-2 (call sign S2 1 1 9) are not 
currently in active service but are authorized as in-orbit spares and are both positioned at the 
nominal 85” W.L. orbital location. 
47 C.F.R. Q 25144(c)(l) Status of space station construction and anticipated launch 
date, including any major problems or delay encountered 
XM-5 (Call Sign TBD). As XM Radio previously advised the Commission, it is 
constructing a fifth satellite, XM-5, at its own risk. See Letter of James S. Blitz, Vice President 
& Regulatory Counsel, XM Radio, to Helen Domenici, Chief, International Bureau, dated 
June 28,2007 at 2. 
47 C.F.R. Q 25.144(~)(2) A listing of any non-scheduled space station outages for more 
than thirty minutes and the cause(s) of such outages 
No unscheduled outages for more than thirty minutes were experienced on XM- 1, XM-2, 
XM-3, or XM-4 during the subject period. 
47 C.F.R. tj 25.144(~)(3) Identification of any space station(s) not available for service 
or otherwise not performing to specifications, the cause(s) of 
these difficulties, and the date any space station was taken out 
of service or the malfunction identified.

XM-1 and XM-2, which are both presently in-orbit spares, are currently able to operate 
within the parameters of the Commission’s authorization. However, as previously disclosed to 
the Commission, both satellites suffer from premature and progressive solar array degradation 
common to all Boeing spacecraft with solar array concentrators (ie., the first five launched 
Boeing 702 spacecraft and the first launched Boeing geo-mobile (GEM) spacecraft). See XM 
Radio Inc., Annual Status Report, at 3 (June 28,2006). This condition was first identified to XM 
by Boeing in August 2001. 
Please contact the undersigned with any questions regarding this matter. 
Very truly yours,
