Before the FEDERAL COMMUNICATIONS COMMISSION Washington, D.C. 20554 ) Application of 1 ) THEDIRECTV GROUP,INC. ) Call Sign: S2 19I ) For Minor Modification to Offset ) File No. Operation of the SPACEWAY 1 ) Ka-band Satellite from 103.05” W.L. to ) 102.8” W.L. 1 APPLICATION FOR MINOR MODIFICATION The DIRECTV Group, Inc. (“DIRECTV”) hereby requests that the Commission modify its authorization for a geostationary Ka-band satellite system at the nominal 103” W.L. orbital location’ to allow DIRECTV to operate at a slight offset - specifically, at 102.8” W.L. This very minor repositioning of the satellite (combined with a similar offset of a companion Ka-band satellite at 99” W.L.) will have major benefits for subscribers receiving Direct-to-Home (“DTH”) satellite services from this slot, as it will enable them to receive a high-quality signal using a smaller dish, and will thereby promote competition as well. In addition, this slight offset will enhance orbital management and decrease the likelihood of in- orbit collision with other satellites. Moreover, as demonstrated herein, the proposed minor modification is anticipated by Commission rules and will not increase harmful interference to any other satellite system. In fact, the only satellite operator potentially affected is a ’ See Public Notice, DA 04-3529 (rel. Nov. 5,2004) (granting modification application for SPACEWAY 1 satellite) (“Mod PN”). 1

DIRECTV subsidiary licensed to operate at the nominal 101' W.L. slot, which will still be able to use its Ka-band frequencies for their intended purpose. DIRECTV intends to launch its SPACEWAY 1 satellite in the spring of next year. Accordingly, expedited consideration of this Application is warranted. I. CHANCES TO PREVJOUS TECHNICAL INFORMATION In this Application, DIRECTV seeks neither additional spectrum nor additional orbital resources, but only a slight offset from its current licensed location consistent with the Commission's rules. In accordance with Section 25.1 17(d)(1 ) of the Commission's rules, DIRECTV identifies in this Application and Technical Annex only those items of information that have changed from its station license and associated application.' DIRECTV hereby certifies that the remaining information in its station license and associated application has not changed. In this case, the only aspects of the satellite's operations reflected in the Technical Annex that will change as a result of moving the satellite from 103.05' W.L.3 to 102.8" W.L. will be: Slightly revised sample link budgets for operations at this slightly offset location. Slightly revised sample link budgets for Ka-band operations from the nominal 101" W.L. orbital location, demonstrating that moving SPACEWAY 1 toward that slot will This Application also includes revised ownership information that reflects the reincorporation of News Corporation in the United States. At the time the Commission assigned Ka-band orbital locations in the first processing round, the applicants for orbital locations between 95" W.L. and 105" W.L. agreed to operate their satellites with a nominal 0.05" offset to the west in order to increase separation from a Luxembourg satellite filing at 93.2" W.L. See Assignment of Orbital Locations to Space Stations in the Ka-Band, 13 FCC Rcd. 1030, Appendix A (Int'l Bur. 1997). This offset was recently made part of the SPACEWAY 1 authorization. See Mod PN at 2. 2

not cause harmful interference to its intended ~ e r v i c e .(The ~ requested eastern offset will move the satellite away from the Ka-band slots to the west (including at 105" W.L.), and so will not increase interference to operations at those locations.) Because moving the satellite only 0.25" will have a de minimis affect on the predicted gain contours, revised contours have not been submitted. 11. THEPROPOSED MODIFICATION WOULD SERVE THE PUBLIC INTEREST DIRECTV is currently authorized to operate a Ka-band system at the 103.05" W.L. orbital location. As contemplated under Section 25.2 10Cj)(3) of the Commission's rules,5 DIRECTV requests that it be authorized to operate at a slight offset from this nominal location, at 102.8" W.L. Although the requested offset is very small -just 0.25" W.L. - it will create large benefits for consumers through improved system performance. Specifically, when combined with a similar (albeit eastward) offset DIRECTV has requested for the companion SPACEWAY 2 Ka-band satellite authorized to operate at 99" W.L., this very slight relocation of the satellite will enable DIRECTV to reduce the size of the satellite dish used by consumers to receive DIRECTV's Ka-band DTH signals. As a result, DIRECTV subscribers will be able to use a single dish of a consumer-friendly size to receive high definition programming (including HD local-into-local signals) from two Ka-band slots, as well as programming from DIRECTV's DBS slots at 101" W.L., 110" W.L., and 119" W.L. This will promote consumer acceptance of DIRECTV's new HD services and help Note that these revised link budgets for 101" W.L. actually reflect operations of DIRECTV 8 from 100.85O W.L. and also include the effect of the companion shift of the SPACEWAY 2 satellite from 99.05' W.L. to 99.2" W.L. 47 C.F.R. $25.210Cj)(3) (operations may be authorized at assigned orbital longitudes offset by 0.05"or multiples thereof from the nominal orbital location specified in the station authorization). 3

DIRECTV continue to provide robust competition to cable operators and other multichannel video programming distributors, to the benefit of the American public. Moreover, DIRECTV's proposal will achieve this improved performance and enhanced competition without causing harmhl interference to any other operator. In fact, as common sense would indicate, by moving slightly away from the adjacent 105" W.L. Ka- band orbital location licensed to SES Americom, DIRECTV will not increase interference to that slot (or any other slots located further West). The proposed offset will move SPACEWAY 1 slightly closer to the 101" W.L. Ka-band orbital location licensed to a DIRECTV subsidiary (DIRECTV Enterprises, LLC), which is planning to launch and operate DIRECTV 8, a hybrid DBS/Ka-band satellite, next year. However, as the attached Technical Annex demonstrates, the proposed offset will not prevent DIRECTV 8 from using its Ka-band payload for its intended function of backhauling local programming from remote sites to DIRECTV's broadcast centers. In addition, this slight offset will allow DIRECTV to operate SPACEWAY 1 in a station keeping volume that does not overlap with either of the other space stations (AMC-1 and Solidaridad-1) operating at the nominal 103"W.L. orbital location.6 This proposal will therefore advance the commission's goal of decreasing the risk of in-orbit collision between space stations7 and also enhance the efficiency with which orbital resources are used. ~~ No other U.S. systems are currently seeking Commission authorization to operate at this nominal orbital location. Internationally, Canada, Tonga, and the United Kingdom currently have coordination requests on file at the ITU for satellite networks at 103"W.L , but DIRECTV has found no evidence that satellite construction contracts have been awarded for any of these networks, and notes that the FAA Commercial Space Station Second Quarter 2004 Report shows no pending launch for any of these networks. ' See, e.g., Mitigation of Orbital Debris, 19 FCC Rcd. 11567, 11588 (2004)(adopting requirements for GEO applicants to assess and coordinate station keeping volumes of any known satellites located at, or reasonably expected to be located at, a requested orbital location). 4

Thus, the proposed offset will have a direct and positive impact on the costumer experience of the DIRECTV service, further enhance competition, and enhance orbital risk management - all without negatively impacting the operations of the DIRECTV system or any other satellite system. The public interest clearly would be served by a grant of the Application. 111. WAIVER PURSUANT TO SECTION 304 OF THE COMMUNICATIONS ACT In accordance with Section 304 of the Communications Act of 1934, as amended, 47 U.S.C. tj 304, DIRECTV hereby waives any claim to the use of any particular frequency or of the electromagnetic spectrum as against the regulatory power of the United States because of the previous use of the same, whether by license or otherwise. IV. CONCLUSION The proposed 0.25" offset of SPACEWAY 1 from its currently licensed orbital location will enable DIRECTV to use a more consumer-friendly receive antenna that will allow it to continue to provide the most potent competition possible to entrenched cable operators. Moreover, this important improvement in performance for DIRECTV's system will not compromise the operational abilities of any other satellite system, and in fact will allow for safer and more effective management of orbital resources. 5

For these reasons, DIRECTV submits that the proposed minor modification request is in the public interest and respectfully requests that the Commission expeditiously grant this request.
