$Exhibit A Request for Special Temporary Authority ViaSat, Inc. requests special temporary authority (“STA”), for a period of 60 days commencing on or about October 19, 2011, to permit ViaSat to: (i) conduct in-orbit testing and short-term operations of the ViaSat-1 satellite at 109.2° W.L. following the launch of that satellite; and (ii) once such activities are complete, move the satellite to 115.1° W.L. To the extent that ViaSat’s application for regular Commission authority to launch ViaSat-1 and operate it at 115.1° W.L (See IBFS File No. SAT-LOA-20110722-00132, as amended) has not been granted in time, ViaSat requests that this STA also cover the launch of ViaSat-1 into 109.2° W.L. 1 Currently pending before the Commission are a series of earth station applications seeking STA to communicate with and conduct telemetry, tracking and control (“TT&C”) related functions for ViaSat-1 during its proposed operations at 109.2° W.L. and its subsequent drift to 115.1° W.L. See IBFS File No. SES-STA-20110526-00632; SES- STA-20110526-00633; SES-STA-20110526-00634; SES-STA-20110526-00635; SES-STA- 20110526-00636; SES-STA-20110526-00637; SES-STA-INTR2011-04402, as amended (“Earth Station STA Requests”). This STA seeks authority for the corresponding spacecraft activities at 109.2° W.L. The scope of those activities, including salient technical parameters, is described or referenced in ViaSat’s Earth Station STA Requests, which ViaSat incorporates by reference. ViaSat-1 currently is at its launch site and being readied for launch in mid- October. ViaSat has coordinated its in-orbit testing, short-term operations, and drift, with potentially affected satellite networks. ViaSat acknowledges that such activities may not cause harmful interference to any other lawfully operating satellite or radio-communication system, and that ViaSat is not entitled to claim protection from interference caused by such satellites or systems. During the drift, only TT&C-related communications will occur. Grant of the requested STA would be consistent with other instances in which the Commission has authorized similar operations. See, e.g., DISH Operating L.L.C., IBFS File No. SAT-STA-20100219-00032 (granted Mar. 11, 2010). As further described in the Earth Station STA Requests, the proposed operations would serve the public interest by allowing ViaSat (i) to ensure that ViaSat-1 is fully operational before locating that satellite to its permanent home at 115.1° W.L., and (ii) to conduct short-term operations at less than full two-degree spacing so that the impact can be fully evaluated for purposes of developing, coordinating, and operating broadband networks in such an environment. Accordingly, ViaSat requests that the Commission grant the requested STA for 60 days, commencing with the expected launch of the satellite on or about October 19, 2011. 1 The Commission already has permitted ViaSat-1 to serve the U.S. from 115.1° W.L., operating under authority granted through the United Kingdom and the Isle of Man. See IBFS File No. SAT-LOI-20080107-00006, as amended. DC\1543996.1$
