INTRODUCTION
AIRTAP COMMUNICATIONS, LLC. (“AIRTAP”), pursuant to 47 C.F.R. § 25.115 of the Rules and
Regulations (“Regulations”) of the Federal Communications Commission (“Commission”),
respectfully requests new authority 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 already licensed hub stations
located in the United States.

The proposed antenna (“Antenna”) is:

    •    Seatel USAT30, 75cm Ku-Band (“Seatel 75cm”) -- Manufactured by Seatel, Inc.

The Antenna is 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 Antenna will meet the requirements of Section 25.222 of the Regulations.

         Antenna Model                           Maximum EIRP Spectral Density
    •    Seatel 75cm (USAT30)                    -21.6 dBW/4KHz

This report together with its attachments and exhibits addresses the requirements of Section
                                                                                             1
25.222 of the Regulations as well as the underlying ESV Order and Orders on Reconsideration.

§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).

                 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

§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 Seatel 75cm will maintain a stabilization pointing accuracy of better than
0.2 degrees under specified ship motion conditions. See Appendix A – Declaration of 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 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 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).

§ 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).

Functionality of Vessel Tracking System
Vessel tracking information at 20 minute intervals, is available real-time from the TDMA
manufacturer Network Management System (NMS) and it is stored in the NMS database
physically situated at the same location as the hub antenna. Should this data be requested by a
frequency coordinator, a fixed operator, the NTIA or the Commission, the database can be
queried and presented in spreadsheet form or displayed on a GUI with map and breadcrumb
history.


§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 AIRTAP 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 Antenna operated by AIRTAP will be controlled by the earth station listed below:
