Purpose of STA:

        The experimental STA is requested to enable Intelsat to test a prototype interface between
a satellite modem and an antenna. The antenna to be used — an AL 7104 System manufactured
by Orbit CT&T Inc. — is described in the attached materials. The interface program will allow the
antenna to track to a desired satellite upon a certain command from the modem based on
geographic location coordinates. This feature on the modem can potentially be used for mobile
applications.

Equipment To Be Used:

        The development and live-via-satellite testing of this feature will require the use of a
transmit/receive antenna that will be installed at Intelsat’s teleport at Clarksburg, Maryland, and will
have access to two of Intelsat’s satellites at orbital locations 325.5 and 335.5 degrees East. The
testing and development will be done at Intelsat’s facilities and under Intelsat’s control.

Restrictions on Operation:

        Intelsat recognizes that the operation of any equipment under experimental authority must
not cause harmful interference to authorized facilities. It therefore will coordinate its activities with
any licensees in the proposed bands in accordance with FCC requirements. Should interference
occur, Intelsat will take immediate steps to resolve the interference, including if necessary
arranging for the discontinuance of operation.

         Intelsat does not propose to market, sell, or lease any prototype equipment to end-users.
After the experimentation ceases, Intelsat would recall and recover any device that are not in
compliance with FCC regulations. If any different treatment becomes necessary during the course
of its experimentation, Intelsat will seek separate and additional authority from the agency.

       In addition, Intelsat will advise entities testing the equipment that permission to operate has
been granted under experimental authority issued to Intelsat, that such operation is strictly
temporary, and that the equipment may not cause harmful interference. Intelsat proposes to label
the equipment or associated written information as follows:

      Analysis of Non-Ionizing Radiation for a 1.2-Meter Earth
                          Station System
This report analyzes the non-ionizing radiation levels for a 1.2-meter earth station system. The
analysis and calculations performed in this report comply with the methods described in the FCC
Office of Engineering and Technology Bulletin, No. 65 first published in 1985 and revised in 1997
in Edition 97-01. The radiation safety limits used in the analysis are in conformance with the FCC
R&O 96-326. Bulletin No. 65 and the FCC R&O specifies that there are two separate tiers of
exposure limits that are dependant on the situation in which the exposure takes place and/or the
status of the individuals who are subject to the exposure. The Maximum Permissible Exposure
(MPE) limits for persons in a General Population/Uncontrolled environment are shown in Table 1.
The General Population/Uncontrolled MPE is a function of transmit frequency and is for an
exposure period of thirty minutes or less. The MPE limits for persons in an
Occupational/Controlled environment are shown in Table 2. The Occupational MPE is a function of
transmit frequency and is for an exposure period of six minutes or less. The purpose of the
analysis described in this report is to determine the power flux density levels of the earth station in
the far-field, near-field, transition region, between the subreflector or feed and main reflector
surface, at the main reflector surface, and between the antenna edge and the ground and to
compare these levels to the specified MPEs.

1.      Far Field Distance Calculation

The distance to the beginning of the far field can be determined from the following equation:

     Distance to the Far Field Region                       Rff = 0.60 D2 / λ                   (1)
                                                                = 41.0 m

The maximum main beam power density in the far field can be determined from the following
equation:

     On-Axis Power Density in the Far Field                 Sff = G P / (4 π Rff 2)             (2)
                                                                = 7.456 W/m2
                                                                = 0.746 mW/cm2

2.      Near Field Calculation

Power flux density is considered to be at a maximum value throughout the entire length of the
defined Near Field region. The region is contained within a cylindrical volume having the same
diameter as the antenna. Past the boundary of the Near Field region, the power density from the
antenna decreases linearly with respect to increasing distance.

The distance to the end of the Near Field can be determined from the following equation:

     Extent of the Near Field                               Rnf = D2 / (4 λ)                    (3)
                                                                = 17.1 m

The maximum power density in the Near Field can be determined from the following equation:

     Near Field Power Density                               Snf = 16.0 η P / (π D2)             (4)
                                                                = 17.406 W/m2
                                                                = 1.741 mW/cm2

3.      Transition Region Calculation

The Transition region is located between the Near and Far Field regions. The power density
begins to decrease linearly with increasing distance in the Transition region. While the power
density decreases inversely with distance in the Transition region, the power density decreases
inversely with the square of the distance in the Far Field region. The maximum power density in
the Transition region will not exceed that calculated for the Near Field region. The power density
calculated in Section 1 is the highest power density the antenna can produce in any of the regions
away from the antenna. The power density at a distance Rt can be determined from the following
equation:

     Transition Region Power Density                        St = Snf Rnf / Rt                   (5)
                                                               = 1.741 mW/cm2

4.      Region between the Main Reflector and the Subreflector

Transmissions from the feed assembly are directed     toward the subreflector surface, and are
reflected back toward the main reflector. The most    common feed assemblies are waveguide
flanges, horns or subreflectors. The energy between   the subreflector and the reflector surfaces
can be calculated by determining the power density    at the subreflector surface. This can be
determined from the following equation:

     Power Density at the Subreflector                    Ssr = 4000 P / Asr                (6)
                                                              = 60.361 mW/cm2

5.      Main Reflector Region

The power density in the main reflector is determined in the same manner as the power density at
the subreflector. The area is now the area of the main reflector aperture and can be determined
from the following equation:

     Power Density at the Main Reflector Surface      Ssurface = 4 P / Asurface             (7)
                                                               = 21.221 W/m2
                                                               = 2.122 mW/cm2


6.      Region between the Main Reflector and the Ground

Assuming uniform illumination of the reflector surface, the power density between the antenna and
the ground can be determined from the following equation:

     Power Density between Reflector and Ground           Sg = P / Asurface                 (8)
                                                             = 5.305 W/m2
                                                             = 0.531 mW/cm2

It is the applicant's responsibility to ensure that the public and operational personnel are not
exposed to harmful levels of radiation.



8.     Conclusions

Based on the above analysis it is concluded that the FCC MPE guidelines have been exceeded (or
met) in the regions of Table 4 and 5. The applicant proposes to comply with the MPE limits by one
or more of the following methods.


Means of Compliance Uncontrolled Areas

This antenna will be located in a fenced area. The fenced are will be sufficient to prohibit the
general public from having access the areas that exceed the MPE limits

Since one diameter removed from the main beam of the antenna or ½ diameter removed from the
edge of the antenna the RF levels are reduced by a factor of 100 or 20 dB. None of the areas
exceeding the MPE levels will be accessible by the general public.

Radiation hazard signs will be posted while this earth station is in operation.

The applicant will ensure that no buildings or other obstacles will be in the areas that exceed the
MPE levels.


Means of Compliance Controlled Areas


The earth station’s operational personnel will not have access to the areas that exceed the MPE
levels while the earth station is in operation.

The transmitters will be turned off during antenna maintenance.
