                        EXHIBIT C – AM44 TECHNICAL NARRATIVE

This exhibit demonstrates compliance with applicable Commission requirements for non-United
States licensed systems.1

1.0 - Introduction




NewCom International (“NewCom”) proposes to serve the United States market using a new
satellite designated as the Express AM44 (“AM44”). The AM44 operates from the orbital
location of 11.0 degrees west longitude. The AM44 will serve North America in the frequency
bands 5975 – 6525 MHz and 3650 – 4200 MHz. The AM44 replaces the Express 3A spacecraft,
which previously served the U.S. market from the same orbital location pursuant to special
temporary authority.2 NewCom will use the AM44 to provide customers in underserved areas
with data services, including Internet backbone access. NewCom’s proposed services will be
exclusively non-common carrier and configured Single Channel Per Carrier (“SCPC”).

The technical characteristics and parameters of the AM44 spacecraft as well as its compliance
with the various provisions of Part 25 of the Commission’s rules are provided in the remainder of
this Technical Narrative.

2.0 - Spacecraft Overview

The AM44 is a 3-axis stabilized spacecraft with a sealed, cylinder shaped body (“platform” or
“structure”) that supports electronic, electrical and other subsystems. The AM44 utilizes two
deployable solar array wings and a propulsion system that consists of SPT-M100 xenon based
plasma thrusters for orbital maneuvers and hydrazine fueled electro-thermocatalytic thrusters for
attitude adjustments. The telecommunications payload module is integrated on the forward
section of the platform. A summary of the physical characteristics of the spacecraft is provided
in Table 1.0 below.

        2.1         Structure

The AM44’s structure provides mechanical support for all subsystems. It also provides a stable
platform for preserving the alignment of critical elements of the spacecraft.

                                                                                             Exhibit C

Electronic subsystems and complementary electronic and electrical components are located
within the sealed, pressurized cylinder. Batteries, fuel tanks, solar arrays and structural elements
that interconnect the telecommunications module with the cylinder platform are mounted
externally in ruggedized modules.

The forward section of the cylinder structure supports the telecommunications module.
Commercial communications antennas, telecommand and telemetry antennas, repeaters and
optical sensors are mounted externally to the telecommunications module.

The AM44 utilizes the following antennas:
   • C-, Ku- and L-band communications antennas.
   • Omnidirectional antennas for Telemetry, Telecommand and Control (“TT&C”) during
      routine and emergency maneuvers.

The spacecraft utilizes two deployable solar arrays, which are mounted to the aft of the primary
cylinder structure. The solar arrays provide the mounting surface for the solar cells. The solar
arrays are connected to the main spacecraft platform through a dedicated solar array drive
assembly.

The AM44’s mass is provided below in Table 2.0 and in the complementary Schedule S.

TABLE 2.0

        2.2      Thermal Subsystem

Thermal control is accomplished through a combination of optical solar reflectors (“OSRs”),
fluid loop equipment, insulation blankets and electrical heaters. The outer surface of the
telecommunications payload module and the platform’s radiator are covered with OSRs to
maximize the heat rejection to space while minimizing the absorbed solar energy. The heat
generated by high power sub-systems (e.g., TWTAs) is removed by a fluid loop and dissipated in
a radiator. Insulation blankets cover the majority of external surfaces areas, with the exception
radiating components and solar arrays. Heaters limit the effects of extreme low temperatures on
electronics, thrusters and propellant lines.

        2.3      Power Subsystem

The power subsystem generates, conditions, stores and protects the AM44’s electrical power. It
also provides the energy required to operate the satellite during all modes of operation. The

power subsystem consists of the solar arrays, batteries, associated electronics, and power
harnesses that interconnect and control the systems.

The AM44 utilizes two deployable solar array wings, which are mounted to the aft section of the
primary cylinder structure. Each solar array is composed of multiple solar panels. Each panel
supports an array of solar cells. Subsequent to launch, both arrays were successfully unfurled.
The AM44’s solar arrays are designed to provide power to the spacecraft for at least 12 years.

Power from the solar arrays is transferred to the spacecraft through the use of a solar array drive
assembly. During eclipse periods, rechargeable multiple cell batteries are the primary source of
power to the spacecraft.

The AM44’s power subsystem has been designed so that no single failure in the subsystem will
cause a spacecraft failure. The subsystem will provide sufficient power to the spacecraft
throughout its design life to support commercial communications, as well as all housekeeping
activities. The beginning-of-life and end-of-life power budgets for the AM44 are provided
below in Table 3.0 and in the complementary Schedule S.

        2.4       Attitude Control Subsystem

The attitude control subsystem will maintain the spacecraft’s attitude during geostationary
operations. Additionally, the attitude control subsystem will be responsible for reacquisition of
the spacecraft in case of emergency.

The attitude control subsystem employs redundant sun and earth sensors and inertial reference
units to perform all attitude determination functions. Physical control of the spacecraft’s attitude
is accomplished through the use of redundant gyrostabilizers and pulsed or continuous firing of
selected thrusters.

        2.5       Propulsion Subsystem

The propulsion subsystem will provide impulse for the spacecraft maneuvering during all phases
of the mission beginning with launch vehicle separation and continuing throughout the satellite’s

                                                                                     Exhibit C
operational life. The spacecraft will employ a propulsion system utilizing plasma thrusters and
electro-thermocatalytic thrusters. The primary components of the propulsion system are:
    • xenon tanks
    • hydrazine tanks
    • plasma thrusters
    • eletro-thermocatalytic thrusters
    • orbit control propulsion subsystem management unit
    • attitude control propulsion subsystem management unit
    • inter-unit pipes

The AM44 was successfully placed into geostationary orbit by a direct injection launch. Orbit
control thrusters maintain the orbital position of the satellite and are mounted at various sites on
the primary cylinder structure.

The architecture of the propulsion sub-system is an evolution of the 727 Express M bus utilizing
space-proven components. The system incorporates full redundancy for all critical components.

       2.6     Satellite Station-Keeping

The AM44 will maintain an operational orbit within 0.05º of its nominal orbital position in both
east-west and north-south directions in full compliance with the provisions of Section 25.210(j)
of the Commission’s Rules.

The attitude of the AM44 will be maintained consistent with industry best practices. Satellite
attitude will satisfy all performance obligations after incorporating potential error sources (i.e.,
attitude perturbations, misalignments, orbital tolerances, thermal distortions and thruster
perturbations).

       2.7     Satellite Lifetime

The AM44 is designed to provide commercial communications from its nominal orbital position
for a period of 12 years. To enhance the probability of survival, component redundancy is
incorporated into the spacecraft design where possible. Materials and processes were selected so
that aging and natural wearing will not adversely affect spacecraft performance during the
estimated life of the AM44.

       2.8     Satellite Reliability

Reliability is maximized by incorporating flight proven components to the greatest extent
possible. All subsystems and components have a minimum design life of 12 years. All critical
components are redundant. All single points of failure have been eliminated, except for the tanks
and tubes of the propulsion subsystem.

The AM44 has 10 active transponders operating in C-band frequencies.3 All C-band
transponders support 40 MHz channels and employ circular polarization.4 The AM44 is the
replacement spacecraft for a series of circular polarized satellites, the most recent of which is the
Express 3A. The use of circular polarization will allow long-standing, legacy customers with
limited resources to continue utilizing the 11.0° W.L. orbital slot without retrofitting earth station
facilities. C-band transponder assignments are provided below in Table 4.0.

Table 4.0

The AM44’s C-band transponders are not capable of switching polarizations.5 With regard to
neighboring satellites, the Russian Satellite Communications Company (“RSCC”) operates the
AM44 in a manner that is compliant with existing coordination agreements and within the same
levels that were utilized on the Express 3A. Hence, the lack of C-band polarization switching
capability aboard the AM44 does not affect compatibility with the co-frequency operation of the
following:

Inmarsat 3F2 @ 15.5W

3
         In addition, the AM44 incorporates 16 Ku-band transponders. The AM44’s Ku-band transponders do not
radiate over the conterminous United States or U.S. territories. NewCom accordingly seeks a waiver of the
obligation in Section 25.137 to provide technical specifics regarding these transponders. Please see Exhibit D.
4
          The AM44 is not strictly in compliance with the provisions of Section 25.210(a)(1) of the Commission’s
Rules that require orthogonal linear polarization in the 5975 – 6425 MHz and 3700 – 4200 MHz frequency bands.
Section 25.210(a)(1), however, applies to satellites providing “domestic service.” The AM44 is designed to provide
intercontinental communications and will not provide “domestic service.” In fact, the low look angle from the
satellite physically prevents inland ground stations in the conterminous U.S. from using the AM44 as a point of
communication.
5
         The AM44 is not strictly compliant with Section 25.210(a)(3) of the Commission’s Rules. As discussed
above, the satellite will not provide domestic service.

Further, the footprint of the AM44 is optimized for 11.0° W.L. Unlike satellites designed to
operate from different orbital locations in the U.S. domestic arc, the AM44 cannot be readily
relocated to another orbital location. Given that many satellites operating outside the U.S. arc do
not have identical beam coverage or homogeneous channel bandwidth and/or spacing, the need
to switch polarization in order to minimize the level of interference to other nearby satellites is
not expected to arise. Accordingly, incorporation of polarization switching on the AM44 would
not have the same benefits as it would have in the case of a satellite designed to operate in the
U.S domestic orbital arc. See Table 5.0 below for general communications payload
characteristics.

        3.1      Antennas and Beam Coverage

The AM44 will utilize a 4º x 10º C-band transmit/receive antenna to generate longitudinal zone
beam coverage, and a 17º x 17º C-band receive antenna coupled with a 15º x 15º C-band transmit
antenna to generate global beam coverage. The coverage provided by these antennas is shown
below in the format prescribed in Section 25.114(d)(3) of the Commission’s Rules. The peak
Equivalent Isotropic Radiated Power (“EIRP”) of the C-band transmit beams is 47 dBW for zone
beams and 39 dBW for global beams. The peak G/T of the C-band receive beams is +3.5 dB/K
for the zone beams and -7 dB/K for the global beams. The minimum saturation flux density
(“SFD”) corresponding to the peak G/T point of the C-band receive beams is -94 dBW/m2. SFD
at any G/T contours may be determined using the following formula:

SFDD = SFDP +[(G/T)P - (G/T)D] +A
where

SFDD: SFD at desired G/T level (dBW/m2)
SFDP: Minimum SFD at peak G/T (dBW/m2)
(G/T)D: Desired G/T level (dB/K)
(G/T)P: Peak G/T (dB/K)
A = Transponder attenuated setting (dB), ranging from 0 to 16 dB in 1 dB steps

The AM44 transmit and receive beams are designed to have a minimum cross-polarization of 30
dB or greater within the primary coverage area and are fully compliant with Section 25.210(i).

The contour maps below illustrate the coverage and EIRP for the zone and global beams
described above.

       3.2     C-band Transponder Description

Earth-to-space signals in the 5975 – 6525 MHz frequency band are received by a left-hand
polarized receive antenna horn. The output of the receive antenna is routed through, a diplexer, a
test coupler, a band-pass filter and then to a set of wide-band receivers.


                                          Page 12 of 18


                                                                      NewCom International
                                        Application to Add Express AM44 to Call Sign E040267
                                                                                    Exhibit C

The receivers are arranged in a redundant ring, and each uplink can access redundant receivers
by ground command. The receivers establish the system noise figure and down-convert the
received signal to the transmit frequency band. Each receiver operates over the entire 5975 –
6525 MHz band and is designed to have high sensitivity (i.e., good noise performance) and low
cross-talk coefficients (i.e., good linearity characteristics). The AM44 C-band receiver is able to
maintain the frequency of the transmitted (downconverted) signal to within 0.002% of the
desired value over the life of the spacecraft. Accordingly, AM44 C-band transponders are
compliant with the provisions of Section 25.202(e) of the Commission’s rules.

The output of the receivers is distributed to a bank of Input Multiplexors (“IMUXs”) through a
switching network. The IMUXs are filters that provide frequency band separation for each
channel. The output of each IMUX is connected to a dedicated Traveling Wave Tube Amplifier
(“TWTA”) equipped with a linearizer and channel amplifier (“LCTWTA”) through a bank of
redundancy switches. The redundancy switching permits the output of the IMUX to be routed to
a redundant TWTA should the primary unit fail or malfunction.

Each C-band LCTWTA utilizes a TWTA that produces nominal output power of 100 Watts. The
LCTWTAs are configured in redundancy rings. Each LCTWTA may operate in Fixed Gain
Mode (“FGM”) or in Automatic Level Control (“ALC”) mode. When operating in FGM, the
gain of each channel (and its associated transponder saturation flux density) may be
independently adjusted by changing the attenuation of its designated LCTWTA by ground
command. Consequently, the output of each LCTWTA may be varied by ground command over
a range of 16 dB in 1 dB increments. Accordingly, the C-band channels of the AM44 are
compliant with the provisions of Section 25.210(c) of the Commission’s rules. When operating
in ALC mode, the input power into the LCTWTA may be maintained at a specific level chosen
within a range of 16 dB, in 1 dB increments.

The output of each LCTWTA is routed through a bank of switches to redundant Output
Multiplexors (“OMUXs”). The switching network also allows the output of a redundant
LCTWTA to be forwarded to the appropriate OMUX should the primary pair of units fail or
malfunction. The output of the OMUX is connected to the transmit antenna (feed) via a band-
pass filter, a test coupler and a diplexer.

       3.3     Power Flux Density

The power flux density limits for space stations are specified in Section 25.208 of the
Commission’s Rules for the 3650 – 4200 MHz frequency band. For this band the power flux
density (“PFD”) level at the Earth’s surface produced by AM44 was calculated for a 40 MHz
digital carrier, using worst case parameters. As shown in Table 6.0, the downlink PFD levels of
this carrier do not exceed the limits specified in Section 25.208(a) of the FCC’s rules. No
contemplated space-to-earth emission will produce PFD levels that exceed the levels created by
the proposed 40 MHz carrier.

       3.8     Link Analysis

In the frequency bands of 5975 – 6525 MHz and 3650 – 4200 MHz, the AM44 will operate in
accordance with existing coordination agreements without generating interference that adversely
affects the operation of adjacent satellites. All ITU coordination obligations in the C-band have
been satisfied.

The results of the C-band analyses are shown in Exhibit H and demonstrate that operation of the
AM44 satellite from 11.0º W.L., within a two-degree environment, would permit the intended
SCPC services to achieve their respective performance objectives while maintaining sufficient
link margin. Additionally, the EIRP density levels of the carriers listed in Exhibit H comply with
the limits contained in Section 25.212(d) of the Commission’s Rules.

       3.9     Adjacent Satellite Link Analysis

The AM44 will operate in accordance with existing coordination agreements. Operation of the
AM44 will be compatible with the operation of existing and planned adjacent satellites.

       3.10    Schedule S Submission

Pursuant to Section 25.114(a) of the Commission’s Rules, NewCom has provided a Schedule S

4.0 - Telemetry

The telemetry, telecommand and control (“TT&C”) subsystem provides the following functions:
   • Collection, processing and transmission of spacecraft telemetry data.
   • Reception, processing and distribution of telecommands.
   • Reception and retransmission of ground station generated ranging signals.

        4.1      Antennas

At all times telemetry and command signals are transmitted and received through
omnidirectional antennas mounted at redundant points on the spacecraft.8

        4.2      Telemetry

During normal on-station operations, telemetry data is transmitted by the AM44 via redundant,
space-to-earth carriers. Specifically, telemetry data from the various subsystems is collected,
processed, aggregated and encoded onto subcarriers. Each encoded subcarrier is modulated onto
the primary space-to-earth carriers. The telemetry transmission is received and decoded at
RSCC’s TT&C operations center.

During transfer orbit maneuvers and emergencies, telemetry data is collected, processed and
encoded in an identical manner to when the satellite is functioning normally, on-station;
however, the output from the telemetry transmitters is routed to a dedicated amplifier. The
amplified signal is then transmitted space-to-earth via an omnidirectional antenna.

        4.3      Ranging

The slant range of the AM44 will be measured throughout the operational life of the spacecraft
using a multiple tone ranging system. The ranging tones are combined with normal command
data and modulated onto the primary command carrier and transmitted to the spacecraft. Upon
reception at the spacecraft the signal is routed to the command receiver where it is separated
from the normal command data and routed directly to the telemetry transmitter for
retransmission to the TT&C operations center on the ground. At RSCC’s TT&C operations
center, the ranging tones are separated from the telemetry data, demodulated and compared with
that of the transmitted signal to determine the range of the satellite.

       5.1     Spacecraft Hardware Design

The AM44 was designed and manufactured by NPO Prikladnoy Mekhaniki (“NPO PM”) in
cooperation with Alcatel Alenia Space France (“AASF”). Specifically, the satellite platform
(727 Express M bus) and subsystems were manufactured by NPO-PM, while the
telecommunications payload module was manufactured by AASF. The 727 Express M bus is a
3-axis stabilized platform that uses a combination of hydrazine and xenon propellants for
stationkeeping and orbit raising maneuvers.

The AM44 spacecraft was designed so that during normal operation debris is not released.
RSCC has assessed the probability of a collision between the spacecraft and meteoroids or small
debris less than one centimeter in diameter (“<1cm debris”). RSCC has taken the following
steps to limit the probability of the AM44 becoming a source of debris due to a collision with
<1cm debris that causes loss of control and prevents post-mission disposal. Specifically:
    • The AM44 has been ruggedized and all critical components are located inside the
        protective outer body of the spacecraft or within ruggedized modules interconnected to
        the body.
    • All AM44 subsystems are redundant, with no single point of failure, except for the tanks
        and tubes associated with the propulsion subsystem.

Based on the architecture of the spacecraft, a single collision with <1cm debris is unlikely to
reach critical subsystems or the satellite’s propulsion system, and to the extent the satellite was
affected by such an event, subsystem redundancy dramatically reduces the probability that RSCC
loses control or is prevented from properly disposing of the spacecraft post-mission.

       5.2     Prevention of Accidental Explosions

RSCC has assessed and limited the probability of accidental explosions during and after
completion of mission operations. In designing the AM44, NPO-PM took appropriate measures
to ensure that debris will not result from the conversion of energy sources on board the
spacecraft into energy that fragments the spacecraft. Specifically:
   • Propellant tanks and thrusters are isolated using redundant valves.
   • Electrical systems are shielded and excessive battery charging or discharging is prevented
       by carefully monitored automated systems.
   • Pressure in batteries and fuel tanks is remotely monitored, and there is significant margin
       between operating pressure levels and burst levels.
   • During stationkeeping maneuvers thruster temperatures, impulse and duration are
       remotely monitored and may be discontinued by closing redundant valves.

At the end of the AM44’s mission, and upon reaching final disposal orbit, all energy sources and
pressurized systems on the spacecraft will be depleted. Residual chemical propellant will be
vented in a controlled manner to maintain perigee height of the final disposal orbit. Batteries
will be left in a permanent state of discharge.

                                                                                             Exhibit C
         5.3      Safe Flight Profiles

RSCC has assessed and limited the probability of the spacecraft becoming a source of debris as a
result of collisions with large debris or other operational space stations. Specifically, RSCC has
evaluated operational and planned ITU coordinated space stations in proximity to the AM44’s
operational orbital position at 11 degrees west longitude. Based on this review, RSCC has
concluded that the AM44’s station keeping volume will not overlap with the volume of another
space station. As a result, at this time there is no requirement to physically coordinate the AM44
with another satellite operator.

         5.4      Post Mission Disposal

Upon the conclusion of its mission, RSCC will dispose of the AM44 by raising it to a minimum
altitude of 235 kilometers above the geostationary arc. This final orbit raising maneuver will
ensure that the AM44 achieves an altitude that exceeds the requirements of the Inter-Agency
Space Debris Coordination Committee (“IADC”) formula.10

RSCC has reserved 1.74 kilograms of fuel for the AM44’s final orbit raising maneuver. RSCC
has assessed fuel gauging uncertainty, and the above referenced volume of propellant provides a
sufficient margin of reserve fuel to address the uncertainty.

   The IADC recommended minimum increase in perigee altitude at the end of re-orbiting, which takes into account
all orbital perturbations, is: 235 km + (1000·Cr x·A/m), where Cr: solar radiation pressure coefficient (typical values
are between 1 & 2), A/m: Aspect area to dry mass ratio [m2/kg].
