Astronics AeroSat will opeUDWHXSWRWZR  ³WDLO-PRXQW´+5DHURQDXWLFDO terminals within the same operational envelope and pursuant to the same terms and conditions embodied in existing experimental license, and will reduce the number of HR6400 terminals to three (3) so that the total number of authorized terminals does not change. The HR123 terminal, manufactured by Astronics AeroSat and designed to be mounted on the tail of ³7-WDLO´EXVLQHVVMHWV(rather than the aircraft fuselage), has been fully certified for aviation safety. Moreover, the terminal has been previously licensed by the Commission for experimental and commercial operations.1 Astronics AeroSat now seeks to test and demonstrate the previously authorized terminal with its new FliteStream network. 1 See The Boeing Company, Radio Station Authorization, Call Sign E000723, File No. SES- MFS-20050701-00853; see also The Boeing Company, Experimental Radio Station Construction Permit and License, Call Sign WC2XVE, File No. 0153-EX-RR-2005.  

  The HR123 terminal complies fully with Section 25.227 of the Commission¶s rules governing earth stations aboard aircraft (³ESAAs´),2 although the terminal will be operated for limited testing and demonstration SXUSRVHVXQGHU$VWURQLFV$HUR6DW¶VH[LVWLQJexperimental authority. Moreover, Astronics AeroSat acknowledges and accepts that the conditions in its existing experimental license will apply to operation of the HR123 terminal, including operation on an unprotected, non-interference basis and the requirement to immediately cease operations in the event of harmful interference. Because the HR123 antenna will operate within the same emissions envelope as the currently authorized HR6400 antenna and Astronics AeroSat will otherwise conform to the conditions of its existing experimental license, operation of the terminal is consistent with Section 5.77 of the &RPPLVVLRQ¶V5XOHV&)5† Please do not hesitate to contact the undersigned with any questions you may have regarding this matter. Respectfully submitted, Carlos M. Nalda Attachment cc (w/ att.): Tony Serafini 2 See 47 C.F.R. § 25.227.
