O3B NON-GEOSTATONARY SATELLITE SYSTEM

Technical Information to Supplement the Existing Schedule S
for the Texas Gateway Earth Station

(FCC File No. SES-LIC-20130124-00089)

A.1 Scope

A Schedule S for the O3b non-geostationary satellite system was filed with the Commission as
part of the license application for the Hawaii gateway earth station. O3b incorporated the
technical information that had been filed with the Hawaii application, including the Schedule S,
in its application for a Texas gateway earth station. This filing supplements the Texas earth
station application by providing modified and additional technical information that is tailored to
the operation of the Texas gateway earth station.

A.2 Predicted Space Station Antenna Gain Contours

The mid-band antenna gain contours for the O3b satellite receive and transmit beams, when
directed towards the Texas gateway earth station, are shown below. Only one set of beam
patterns is provided for transmit and one set for receive because all O3b satellite transmit beams
are identical and all receive beams are identical.

These beam patterns demonstrate the effects on the satellite antenna gain contours as the O3b
satellite moves in its orbit. Various satellite positions are shown starting with the O3b satellite
appearing at 5° elevation angle in the west as viewed from the Texas earth station (see Figure
A.2-1). The next O3b satellite position (Figure A.2-2) is at the point when it is at the same
longitude as the Texas earth station. The third O3b satellite position is when the O3b satellite is
disappearing below the 5° elevation angle in the east as viewed from the Texas earth station
(Figure A.2-3). For each of these Figures both the transmit and receive antenna gain contours are
shown.

A.3 Service Area

The service area designated as “G1” in the original Schedule S for the O3b non-geostationary
satellite system is extended to include the Texas gateway location. The new service area is
therefore defined to be “Haleiwa, HI + Vernon, TX” for the purpose of O3b gateway earth
stations.

A.4 Link Budgets for the Texas Gateway Earth Station

New representative link budgets are provided in Annex 1 for the Texas gateway earth station.
The earth station in Texas is identical to that in Hawaii, and the geometry of the link between the
gateway and the O3b satellite is identical as it is bounded by the minimum elevation angle of 5
degrees. Even the difference in rain region is relatively unimportant because of the use of
adaptive coding and modulation which compensates for rain fades.

A.5 TT&C Characteristics

There is no change to the TT&C information for the O3b non-geostationary satellite system
compared to that provided in the Hawaii gateway earth station application. However, the Texas
earth station will be used primarily for communications traffic as the regional gateway, and will
only be available to perform the TT&C function as a back-up to O3b’s Peru gateway station.

A.6 Coordination with US Government Satellite Networks and Earth Stations

O3b has completed all necessary coordination with US government satellite networks operating
in Ka-band, including GSO and non-GSO, as well as their associated specific earth stations filed
under 9.7A and 9.7B of the ITU Radio Regulations through other administrations. O3b has also
completed coordination, according to US footnote 334 of the FCC table of frequency allocations,
with the US government, and this US334 coordination agreement specifically takes into account
O3b earth stations such as the Texas gateway.

Annex 1 - Representative Link Budgets

The next 22 pages contain representative link budgets for communications transmissions to and
from the Texas gateway earth station.

The three pages following the communications link budgets contain link budgets for the TT&C
links that may be operated from the Texas gateway earth station.
