INTRODUCTION Data Technology Solutions, LLC. (“DTS”), pursuant to 47 C.F.R. § 25.115 of the Rules and Regulations (“Regulations”) of the Federal Communications Commission (“Commission”), respectfully requests the issuance of a new license to operate Ku-Band Earth Station on Vessels (“ESVs”) throughout US channels and waterways, 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 an already licensed hub station located in the United States. The proposed antennas (collectively referred to as the “Antennas”) are: • Seatel 60cm (“Seatel 60cm”) – Manufatured by Cobham SATCOM-Marine Systems (“Seatel”); and • Seatel 75cm (“Seatel 75cm”) -- Manufactured by Cobham SATCOM-Marine Systems. The Antennas are capable of providing stabilized tracking. Seatel has performed tests and generated the EIRP spectral density tables and plots here presented. Furthermore, Seatel 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 of the Regulations. Antenna Model Maximum EIRP Spectral Density • Seatel 60cm -21.6 dBW/4KHz • Seatel 75cm -21.6 dBW/4KHz This report together with its attachments and exhibits addresses the requirements of Section 25.222 of the Regulations as well as the underlying ESV Order and Order on Reconsideration. 1 §25.222 (a)(1)(i)(A-C) SPECTRAL DENSITY LIMITS “An ESV system shall not exceed the off-axis EIRP spectral-density limits and conditions defined in paragraphs (a)(1)(i)(A) through (a)(1)(i)(D) of this section.” 47 C.F.R §25.222(a)(1)(i)(A). Spectral Density Envelopes The spectral density envelopes specified in §25.222(a)(1)(i) are as follows: 2 §25.222(a)(1)(i)(A) – Copole Azimuth • 15 – 25log(θ) dBW / 4KHz for 1.5° ≤ θ ≤ 7.0º • -6 dBW / 4KHz for 7.0° ≤ θ ≤ 9.2º • 18 – 25log(θ) dBW / 4KHz for 9.2° ≤ θ ≤ 48º • -24 dBW / 4KHz for 48° ≤ θ ≤ 85º • -14 dBW / 4KHz for 85° ≤ θ ≤ 180º The peak EIRP of an individual sidelobe may not exceed the envelope defined above for θ between 1.5 º and 7.0 º. For θ > 7º, the envelope may be exceeded by no more than 10% of the sidelobes, provided no individual sidelobe exceeds the envelope by more than 3dB. §25.222(a)(1)(i)(B) – Copole in other directions • 18 – 25log(θ) dBW / 4KHz for 3.0° ≤ θ ≤ 48º 1 In the Matter of Procedures to Govern the Use of Satellite Earth Stations on Board Vessels in the 5925-6425 MHz/3700-4200 MHz Bands and 14.0-14.5 GHz/11.7-12.2 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 31, 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. 2

• -24 dBW / 4KHz for 48° ≤ θ ≤ 85º • -14 dBW / 4KHz for 85° ≤ θ ≤ 180º The envelope may be exceeded by no more than 10% of the sidelobes provided no individual sidelobe exceeds the gain envelope given above by more than 6dB. The region of the main reflector spillover energy is to be determined as a single lobe and shall not exceed the enveloped by more than 6dB. §25.222(a)(1)(i)(C) – Crosspole Azimuth • 5 – 25log(θ) dBW / 4KHz for 1.8° ≤ θ ≤ 7º • -16 dBW / 4KHz for 7° ≤ θ ≤ 9.2º §25.222 (a)(1)(ii)(A) ANTENNA POINTING ERROR “Each ESV transmitter shall maintain a pointing error of less than or equal to 0.2° between the orbital location of the target satellite and the axis of the main lobe of the ESV antenna.” 47 C.F.R §25.222(a)(1)(ii)(A). According to Seatel, the Antennas will maintain a stabilization pointing accuracy of better than 0.2 degrees under specified ship motion conditions. See Appendix A – Declaration of Cobham SATCOM, Seatel, Inc., Paragraph 4. §25.222 (a)(1)(iii)(A) AUTOMATIC SHUT-OFF “… all emissions from the ESV shall automatically cease within 100 milliseconds if the line angle between the orbital location of the target satellite and the axis of the main lobe of the ESV antenna exceeds 0.5°, and transmission will not resume until such angle is less than 0.2°.” 47 C.F.R §25.222(a)(1)(iii)(A). According to Seatel, the Seatel 60cm and Seatel 75cm will automatically cease transmissions within 100 milliseconds if the pointing error should exceed 0.5 degrees and will not resume transmissions until the error drops below 0.2 degrees. See Appendix A – Declaration of Cobham SATCOM, Seatel, Inc., Paragraph 5. §25.222 (a)(3) U.S. CONTACT INFORMATION “There shall be a point of contact in the United States, with phone number and address included with the application, available 24 hours a day, seven days of week, with authority and ability to cease all emissions from the ESVs, either directly or through the facilities of a U.S. Hub or a Hub located in another country with which the U.S. has a bilateral agreement that enables such cessation of emissions.” 47 C.F.R §25.222(a)(3). Data Technology Solutions, Inc. Mike Guidroz 1300 N. Berard St. Breaux Bridge, LA 70517 (337) 332-4347 phone DTS personnel, either via a network port or an out-of-band management system, have the authority and capability to remotely access equipment on the ESV to terminate emissions in case of suspected interference. § 25.222 (a)(4) VESSEL TRACKING “For each ESV transmitter a record of the ship location (i.e. latitude/longitude), transmit frequency, channel bandwidth and satellite used shall be time annotated and maintained for a period of not less than 1 year. Records will be recorded at time intervals no greater than every 20 minutes while the ESV is transmitting. The ESV operator will 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 (a)(4). 3

Functionality of Vessel Tracking System DTS 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 DTS’s Network Management System (NMS) on a regular basis. DTS 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.

Vessel Tracking Network Configuration §25.222 (a)(5) VESSELS OF FOREIGN REGISTRY “ESV operators communicating with vessels of foreign registry must maintain detailed information on each vessel’s country of registry and a point of contact for the relevant administration responsible for licensing ESVs.” 47 C.F.R. §25.222 (a)(5). In the event DTS must operate foreign-registered ESVs, it will maintain detailed information on each vessel as well as a point of contact for the relevant administration responsible for licensing the ESV. §25.222 (a)(6) U.S. CONTROL OF ESV HUB EARTH STATION “ESV operators shall control all ESVs by a Hub earth station located in the United States, except that an ESV on U.S.- registered vessels may operate under control of a Hub earth station location outside the United States provided the ESV operator maintains a point of contact within the United States that will have the capability and authority to cause an ESV on a U.S.-registered vessel to cease transmitting if necessary.” 47 C.F.R. §25.222 (a)(6). The Antennas operated by DTS will be controlled by the earth station listed below: Callsign Diameter Location Antenna ID KA399 3 9.0m Mt. Jackson* 9.0M *1305 Industrial Park Road, Mount Jackson, Shenandoah, VA 22842 DTS wishes to make the following statements regarding control of the ESV stations: • DTS wishes to use Telesat’s satellites only on the range of frequencies assigned to DTS by Telesat. This is pursuant to an agreement between DTS and Telesat whereby DTS is solely responsible for operation and management of these frequencies. 3 This 9m antenna is licensed for Ku ESV operations. See file number SES-MOD-20090206-00154 granted January 1, 2010. 4

• DTS, and not Telesat, will be the network operator and will be entirely responsible for compliance with all Commission requirements contained in Sections 25.222 and 25.271 of the Regulations. This is to include: providing 24X7 call center coverage, ESV location data collection and retention, and automatic shutdown of the ESVs. Furthermore, DTS will be the only party capable of managing the network with appropriate authority to terminate transmissions if and when the Commission requests to do so. • DTS seeks to add Telesat’s 9m antenna to DTS’s ESV network because DTS does not currently have a hub antenna available that is capable of accessing Telstar 11N. • DTS understands that if DTS were to cease providing service over Telesat’s 9m antenna, it will relinquish control of the frequencies assigned by Telesat and turn them back to Telesat for assignment to another one of Telesat’s customers.

Network Diagram §25.222 (a)(7) 10.95-11.2 GHz “In the 10.95-11.2 GHz (Earth-toSpace) frequency bands ESVs shall not claim protection from interference from any authorized terrestrial stations to which frequencies are either already assigned, or may be assigned in the future.” DTS will not claim protection from interference in the 10.95-11.2GHz from any authorized terrestrial stations to which frequencies are already assigned or may be assigned in the future. §25.222 (b)(1)(i) EIRP DENSITY TABLES “Any ESV applicant filling an application pursuant to paragraph (a)(1) of this section must file three tables showing the off-axis EIRP level of the proposed earth station antenna in the direction of the place of the GSO; the co-polarized EIRP in the elevation plane, that is, in the place perpendicular to the plane of the GSO; and cross-polarized EIRP. In each table, the EIRP level must be provided at increments of 0.1° for angles between 0° and 10° off-axis, and at increments of 5° for angles between 10° and 180° off-axis. .” 47 C.F.R §25.222(b)(1)(i). DTS has provided spectral density tables as well as charts as exhibits to Form 312 of the underlying application. Such tables and charts were generated by Seatel for the Seatel 60cm and Seatel 75cm antennas. 5

§25.222 (b)(1)(ii) DTS CERTIFICATION “A certification, in Schedule B, that the ESV antenna conforms to the gain pattern criteria of §25.209 (a) and (b), that, combined with the maximum input power density calculated from the EIRP density less the antenna gain, which is entered in Schedule B, demonstrates that the off-axis EIRP density envelope set forth in paragraphs (a)(1)(i)(A) through (a)(1)(i)(C) of this section will be met under the assumption that the antenna is pointed to the target satellite.” 47 C.F.R §25.222(b)(1)(ii). See Appendix B – Certification of DTS §25.222 (b)(1)(iii) MANUFACTURER CERTIFICATION “An ESV applicant proposing to implement a transmitter under paragraph (a)(1)(ii)(A) of this section, must provide a certification from the equipment manufacturer stating that the antenna tracking system will maintain a pointing error of less than or equal to 0.2° between the orbital location of the target satellite and the axis of the main lobe of the ESV antenna and the antenna tracking system is capable of ceasing emissions within100 milliseconds in the angle between the orbital location of the satellite and the axis of the main lobe of the ESV antenna exceeds 0.5°.” 47 C.F.R §25.222(b)(1)(iii). According to Seatel, the Seatel 60cm and Seatel 75cm will automatically cease transmissions within 100 milliseconds if the pointing error should exceed 0.5 degrees and will not resume transmissions until the error drops below 0.2 degrees. See Appendix A – Declaration of Cobham SATCOM, Seatel, Inc., Paragraph 5. §25.222 (b)(3) ESV GEOGRAPHIC AREA OF OPERATION “There shall be an exhibit included with the application describing the geographic area(s) in which the ESVs will operate.” 47 C.F.R §25.222(b)(3). The geographic area where the ESVs will operate is in US channels and waterways, the Gulf of Mexico, Caribbean Sea, Atlantic Ocean, and Pacific Ocean. Figure 3.
