INTRODUCTION Harris CapRock Communications, lnc. ("HARRIS CAPROCK), pursuant to 47 C,F,R. S 25.117 of the Rules and Regulations ("Regulations") of the Federal Communications Commission ("Commission"), respectfully requests the modification of an existing license to operate new Ku-Band Earth Station on Vessels ("ESVs") throughout US channels and watenrrrays, the Gulf of Mexico, the Caribbean Sea, the Atlantic Ocean, and the Pacific Ocean. The proposed ESVs seek to operate in the 11.7-12.2 GHz and 14.0-14.5 GHz ("Ku-Band")frequency bands to communicate with already licensed hub stations located in the United States and operated by HARRIS CAPROCK. The proposed antenna models ("Antennas") are: o lntellian Ku 60cm model V60 ("lntellian V60) -- Manufactured by lntellian Technologies, lnc. ¡ lntellian Ku 83cm model V80 ("lntellian V80') -- Manufactured by lntellian Technologies, lnc. The Antennas are capable of providing stabilized tracking. lntellian has performed tests and generated the EIRP spechal density tables and plots here presented. Furthermore, lntellian has declared that if the input power density to the feed of the Antennas is limited to the figures stated below, the Antennas will meet the requirements of Section 25.222 oÍ the Regulations. Antenna Model Maximum EIRP Spectral Densitv . lntellian V60 -22,30 dBW4KHz . lntellian V80 -20.13 dBW4KHz This report together with its attachments and exhibits addresses the requirements of Section 25.222 of lhe Regulations as well as the underlying ESV Order and Order on Reconsideration,r 525.222 (a)(1 )(i)(A-c) SPECTRAL DENSITY LlMlTs 'An ESVsysfem shall not exceed the off-axrs E/RP spectral-density limits and conditions defined in paragraphs (a)(t)(il(fl throush (a)(tXt)(D) of this section." 47 C.F.R 525.222(a)(1)(¡)(A). Spe ctral D e n sitv Enve I ope s The spectral density envelopes specified in $25.222(a)(1)(i) are as follows:z . 15 - 25log(0) dBW / 4KHz for 1 .5'< g < 7.0o o -$ dBW / 4KHzfor 7.0"< 0 < 9.2o . 18 - 25log(0) dBW / 4KHz for 9.2'< 0 < 48o . -24 dBW / 4KHzfor 48'< 0< 85o . -14 dBW / 4KHzfor 85'< 0< 1800 The peak EIRP of an individualsidelobe may not exceed the envelope o o. For 0 > 70, the envelope defined above for 0 between 1.5 and 7.0 may be exceeded by no more than 10% of the side/obes, provided no individual sidelobe exceeds the envelope bv more than 3dB. 1 In the Matter of Procedures to Govem the (Jse of Satellite Earth Stations on Board Vessels in the 5925-6425 MHz/3700-4200 MHz Bands and 14.0-14.5 GHz/l1.7-12.2 GHz Bands, Report and Order, FCC 204-286, Adopted December 15, 2004, Released January 6, 2005; Order on Reconsideration, FCC 09-63, Adopted July 30, 2009, Released July 3 1, 2009. 2 The actual formula in the statute includes a log(N) term which is subtracted from the spectral density. Since in this case, the system is TDMA and N=1 for TDMA, the log(1) terms goes to zero.

The envelope may be exceeded by no more than 10% of the srde/obes provided no ìndividual sideloóe exceeds the gain envelope given above by more than 6dB. The region of the maín reflector spillover energy is to be determined as a single lobe and shall not exceed the enveloped more than 6dB. 925.222 (aXlXiiXA) ANTENNA POINTING ERROR "Each ESV transmitter shall maintain a pointing enor of /ess than or equalto 0.2"between the lntellianal location of the target satellite and the axis of the main lobe of the ESV antenna." 47 C.F.R $25.222(a)(1)(it)(A). According to lntellian, the Antennas will maintain a stabilization pointing accuracy of better than 0.2 degrees under specified ship motion conditions. See Declaration of lntellian attached to the underlying application. 525.222 (a)(1 )(iii)(A) AUTOMATIC sHUT-OFF "... áll emissìons from fhe ESV shall automatically cease within 100 milliseconds if the line angle befween the lntellianal location of the target satellite and the axis of the main lobe of fhe ESV antenna exceeds 0.5", and fransmr.ssion willnot resume untilsuch angle is /ess fhan 0.2'.' 47 C.F.R $25.222(a)(1)(iii)(A). According to lntellian, the Antennas will automatically cease transmissions within 100 milliseconds if the pointing enor should exceed 0,5 degrees and will not resume transmissions until the enor drops below 0.2 degrees, See Declaration of lntellian attached to the underlying application. 525.222 (aXs) U,S.

Houston, Texæ 77048 (832) 668-2300 phone HARRIS CAPROCK personnel, either via a network pod or an out-oÊband management system, have the authority and capability to remotely access equipment on the ESVs to terminate emissions in case of suspected interference. 825.222 (a)(a) VESSEL TRACKING "For each ESV transmitter a record of the ship location (i.e. Iatitude/longitude), transmit frequency, channel bandwidth and satellite used sha// be time annotated and maintained for a period of not /ess than 1 year. Records will be recorded at time interuals no greater than every 20 ninutes while the ESV is fransmrtf ing. The ESV operator wíll make this data available upon request to a coordinator, fixed system operator, fixed-satellite system operator, NTIA, or the Commission within 24 hours of the request." 47 C.F.R. $25.222 (Q@,

F unction alitv of Vessel T rackinq Svstem HARRIS CAPROCK has designed a system to record the vessel's location, transmit frequency, channel bandwidth and satellite. The system records this information every 20 minutes, This data will be stored locally and will be uploaded to HARRIS CAPROCK's Network Management System (NMS) on a regular basis. HARRIS CAPROCK can make this data available within 24 hours of a request by a coordinator, fixed system operator, fixed-satellite system operator, NTIA, or the Commission.
