Summary of Potential Impact of ViaSat Aeronautical Antenna Operations on Other Spacecraft October 11, 2012 • Application Status o ViaSat filed an application for Ka band aeronautical terminals on April 27, 2012.  This application is not yet on Public Notice. o STA was requested on August 15, 2012.  Row 44 filed a Petition to Deny the STA request on September 5, 2012, which ViaSat opposed. • Row 44’s Ku band operations are unaffected by this proposal. • No satellite operator has raised any concerns. o STA for market access trials and testing of commercial operations is now needed by November 1, 2012. • Antenna conforms to the “default” Section 25.138 transmit EIRP parameters within +/- 6 degrees, under all expected operating conditions. o Antenna is compliant in the main beam with up to 60 degrees of skew. o The system will inhibit transmissions when the combined skew resulting from geography and banking (i.e., pitch, yaw, roll) equals or exceeds 60 degrees. o Satellite operators within +/- 6 degrees have been informed and have no operational concerns. • Transmit lobes exceed the default Section 25.138 EIRP parameters, at some points located on well-defined radii, measured from the main lobe. o Lobe locations and amplitude vary with transmit frequency. o Details of these excursions by frequency (including the amplitude of the lobe), depicted for skew angles where the worst case excursions occur, are contained in the 161 pages of transmit EIRP density plots included in Exhibit C of the application. o Figure 3 of Exhibit A of the application is an exemplary composite of these data at a given frequency, and showing the GSO arc at three representative skew angles.

o ViaSat has coordinated the excursions outside the GSO plane with O3b. o These excursions potentially affect a limited number of GSO spacecraft at defined longitudes, when skew from aircraft location/banking causes the grating lobes temporarily to intersect with the GSO arc.  Because the grating lobes exist at pre-defined radii (from the main lobe), potentially affected orbital locations are known with 100% certainty at the outset.  Whether the lobes actually intersect with these orbital locations during operation is a function of antenna orientation toward the GSO due to aircraft geographic location/banking.  Whether these lobes actually “affect” any spacecraft is a function of (i) whether the orbital location is occupied at Ka band, (ii) if occupied, whether the relevant transmit frequency that produces the excursion is used on the spacecraft there, (iii) if used, whether it is used on a co-pol, co-coverage basis, and (iv) if used on a co-pol, co-coverage basis, whether the impact is more than de minimis. • The net result is that few orbital locations actually present issues.  ViaSat successfully has coordinated with all potentially affected spacecraft that are operating currently or expected to be operating within the next few years, except for a recently authorized system that ViaSat is currently coordinating with the satellite operator. • As long as all potentially affected satellite operators have signed off, it is not material to the application under which range of skew angles within the geographic service area that these GSO arc intersections arc may occur. o Nor is it relevant to the application precisely in which portions of the geographic service area this intersecting skew can occur. o Row 44 is simply mistaken in focusing on these issues, which potentially could be a concern only for the affected satellite operator. • Regulators in Europe are finalizing a licensing framework to treat earth stations on mobile platforms in the Ka band as an application of the FSS. 2 DC\2312693.4
