$Description of Amendment to Request for Special Temporary Authority ViaSat, Inc. (“ViaSat”) amends its pending requests for Special Temporary Authority (“STA”) to use certain earth station facilities to communicate with its Ka-band ViaSat-1 satellite while at 109.2º W.L. and also while drifting to 115.1º W.L. See FCC File Nos. SES-STA-20110526-00632; SES-STA-20110526-00633; SES-STA-20110526-00634; SES- STA-20110526-00635; SES-STA-20110526-00636; SES-STA-20110526-00637. The attached amended and restated description the STA request reflects the following 1. Clarification that ViaSat-1 will operate under U.S. authority while at the 109.2º W.L. location. Since filing the STA requests, ViaSat has filed an application for Commission authority to launch ViaSat-1 and operate it at 115.1º W.L., and an STA request to operate ViaSat-1 at 109.2º W.L. under U.S. authority. 2. Updated launch date. ViaSat amends the pending STA requests to update the expected date of launch, which is now expected to occur on or about October 19, 2011. 3. Addition of a fourth user terminal. The pending STA request seeks authority to use three user terminals, for which an underlying blanket license application is currently pending. ViaSat amends its STA requests to add an additional user terminal in the vicinity of Portland, Oregon. ViaSat is submitting a separate STA application form to identify the location of this additional terminal. DC\1542132.1$
