1, 1995, 44 U.S.C. SECTION 3507.


                                                   STA Request
                                                     E030115

                 Hawaii Pacific Teleport (HPT) requests special temporary authority ("STA") to operate

the subject C—band and Ku—band earth stations to provide in—orbit testing ("IOT") services for

certain C—band and Ku—band transponders on the recently launched EUTELSAT 172B

("E172B") satellite‘ at the 176° E.L. orbital location. HPT requests this STA for the period of

October 15, 2017 to November 15, 2017.

                 E172B is designed as a replacement for the EUTELSAT 172A ("E172A") satellite at

 172° E.L. and the subject transponders will be operated at its final location by ES 172 LLC, an

indirect subsidiary of Eutelsat, S.A. (collectively, "Eutelsat") (see FCC File No. SAT—RPL—

20170927—00136). The information provided in Eutelsat‘s replacement satellite application is

hereby incorporated by reference.

                 The subject earth stations will test E172B‘s C—band and Ku—band functionality in the

5925—6425 MHz (Earth—to—space) and 3700—4200 MHz (space—to—Earth) bands, and the 14.0—14.5

GHz (Earth—to—space) and 10.95—11.20 GHz, 11.45—11.7 GHz and 12.20—12.75 GHz (space—to—

Earth) bands. HPT understands that, based on Eutelsat‘s analysis and consultations with

potentially affected parties, there is no reason to conclude that E172B‘s temporary IOT

operations in these bands at 176° E.L. will raise interference or other concerns. Nonetheless, to

the extent harmful interference may occur, HPT commits to modifying or suspending its earth




‘ EUTELSAT 172B launched under authority granted by France pursuant to the well—settled
licensing processes of that nation and will arrive shortly at its IOT location. Because France is a
WTO member nation, there is a presumption in favor of granting market access to allow U.S.
earth stations to communicate with French—licensed satellites (assuming compliance with other
applicable Commission rules and policies).


{fon101919—1 }


station transmissions to resolve such interference. Thus, HPT acknowledges that its earth station

operations will be conducted on an unprotected, non—harmful interference basis.

                After IOT, the E172B satellite will be located at 172° E.L. to support long—term service

throughout the Asia—Pacific region, including Ku—band mobility applications, as indicated in the

above—referenced replacement satellite application and an STA request filed by Panasonic

Avionics to access the satellite (see FCC File No. SES—STA—INTR2017—02798). This request for

short—term earth station operating authority to support IOT for E172B is eséential to ensure

proper functioning of the satellite and permit the near—term transition of traffic from E172A.

                Attached is an Exhibit 1 — Technical Exhibit (Schedule B of Form 312) — detailing the

requested operating parameters for IOT on the C—band and Ku—band operations. Attached as

Exhibits 2 and 3 are Radiation Hazard Reports for IOT on the C—band and Ku—band operations.

Attached as Exhibit 4 are Frequency Coordination Reports for IOT earth station operations.

1. CONCLUSIONS



An interference study considering all existing, proposed and prior coordinated microwave
facilities within the coordination contours of the proposed earth station demonstrates that
this site will operate satisfactorily with the common carriere microwave environment.
Further, there will be no restrictions of its operation due to interference considerations.




Frequency Coordination and Interference Analysis Report   08/31/2017         Page 3 of 10


2. SUMMARY OF RESULTS



A number of great circle interference cases were identified during the interference study of
the proposed earth station. Each of the cases, which exceeded the interference objective
on a line—of—sight basis, was profiled and the propagation losses estimated using NBS
TN101 (Revised) techniques. The losses were found to be sufficient to reduce the signal
levels to acceptable magnitudes in every case.

The following companies reported potential great circle interference conflicts that did not
meet the objectives on a line—of—sight basis. When over—the—horizon losses are considered
on the interfering paths, sufficient blockage exists to negate harmful interference from
occurring with the proposed transmit—receive earth station.

      Analysis of Non—lonizing Radiation for a 4.5—MeterEarth
                          Station System
This report analyzes the non—ionizing radiation levels for a 4.5—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                        Rg = 0.60 D/A                          (1)
                                                               = 250.1 m

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

   On—Axis Power Density in the Far Field                   S¢        GP/(4 1 R;*)                 (2)

                                                                      11.746 W/im*
                                                                      1175 mW/icm*




                                                                 1P
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                                 Ry = D/ (4 )                           (3)
                                                               = 104.2 m

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

   Near Field Power Density                                 Sar = 16.0 7 P / (r D)                 (4)
                                                                 = 27.420 W/im*
                                                                 = 2.742 mWicm*

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 R, can be determined from the following
equation:

   Transition Region Power Density                          S =Sna Rn/ R                           (5)
                                                                 = 2.742 mWicm*


Radiation Hazard Report                                                               Page 3 of 5
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                      Ss;r = 4000 P / Ag;                       (6)
                                                                = 250.456 mW/icm*

4. 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        Ssurtace 7 4 P / Asurface                     (7)
                                                                = 45.271 W/im*
                                                                = 4.527 mWicm*


5. 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             Sq

                                                                      11.318 W/im"

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




7. 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 area will be sufficient to prohibit access to the
areas that exceed the MPE limited. The general public will not have access to areas within %
diameter removed from the edge of the antenna.

Since one diameter removed from the main beam of the antenna or % 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 oiher obstacles will be in the areas that exceed the
MPE levels.


Means of Compliance Controlled Areas

The earth stations operational 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.

The applicant agrees to abide by the conditions specified in Condition 5208 provided below:

Condition 5208 — The licensee shall take all necessary measures to ensure that the antenna does
not create potential exposure of humans to radiofrequency radiation in excess of the FCC
exposure limits defined in 47 CFR 1.1307(b) and 1.1310 wherever such exposures might occur.
Measures must be taken to ensure compliance with limits for both occupational/controlled
exposure and for general population/uncontrolled exposure, as defined in these rule sections.
Compliance can be accomplished in most cases by appropriate restrictions such as fencing.
Requirements for restrictions can be determined by predictions based on calculations, modeling or
by field measurements. The FCC‘s OET Bulletin 65 (available on—line at www.fec.gov/oet/rfsafety)
provides information on predicting exposure levels and on methods for ensuring compliance,
including the use of warning and alerting signs and protective equipment for worker.

      Analysis of Non—lonizing Radiation for a 4.8—Meter Earth
                          Station System
This report analyzes the non—ionizing radiation levels for a 4.8—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 Ffeld Distance Calculation

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

    Distance to the Far Field Region                        R; =0.60 D/A                              (1)

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                                 Ry = D& / (4 )                            (3)
                                                               = 273.6 m

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

   Near Field Power Density                                 Sar = 16.0 1 P / (1 D)                    (4)
                                                                  = 24.524 W/im*
                                                                  = 2.452 mWicm*

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 R, can be determined from the following
equation:

   Transition Region Power Density                          S. = SRa/R                                (5)
                                                               = 2.452 mWicm*

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 / Ag;                    (6)
                                                               = 250.456 mWi/icm*

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 / Asurtace                 (7)
                                                              = 39.789 W/m*
                                                              = 3.979 mW/cm*


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 / Agurtace                      (8)
                                                              = 9.947 W/m*
                                                              = 0.995 mW/cm*

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 area will be sufficient to prohibit access to the
areas that exceed the MPE limited. The general public will not have access to areas within !%
diameter removed from the edge of the antenna.                                    ,

Since one diameter removed from the main beam of the antenna or !% 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 stations operational 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.



The applicant agrees to abide by the conditions specified in Condition 5208 provided below:

Condition 5208 — The licensee shall take all necessary measures to ensure that the antenna does
not create potential exposure of humans to radiofrequency radiation in excess of the FCC
exposure limits defined in 47 CFR 1.1307(b) and 1.1310 wherever such exposures might occur.
Measures must be taken to ensure compliance with limits for both occupational/controlled
exposure and for general population/uncontrolled exposure, as defined in these rule sections.
Compliance can be accomplished in most cases by appropriate restrictions such as fencing.
Requirements for restrictions can be determined by predictions based on calculations, modeling or
by field measurements. The FCC‘s OET Bulletin 65 (available on—line at www.fec.gov/oet/rfsafety)
provides information on predicting exposure levels and on methods for ensuring compliance,
including the use of warning and alerting signs and protective equipment for worker.
