                                                Exhibit A

                                DESCRIPTION OF STA REQUEST

    I.     DESCRIPTION OF STA REQUEST

             ISAT US, Inc. (“ISAT US”) hereby requests special temporary authority (“STA”) to
    operate its two licensed aero earth station terminal types in additional frequency bands in
    and around the Orlando, Florida area to facilitate a demonstration during the National
    Business Aviation Association (NBAA) convention using the Inmarsat 5 F2 (I5F2) satellite.
    The earth station antenna types are the MCS 8000 and the MCS 8200 (“Antennas”) that are
    already licensed by the Commission to operate in the 29.5-30.0 GHz and 19.7-20.2 GHz
    bands. There will be up to two of each type of earth station operating under this STA.
    Operations of the Antennas during the demonstration period would be within the envelope
    of the technical parameters of the existing license with the exception of additional frequency
    bands discussed below. 1 The Antennas will operate with the Inmarsat Global Xpress I5 F2
    satellite from the 55º W.L. orbital location and the Lino Lakes Satellite Access Station,
    which have both been authorized for U.S. market access. 2

            ISAT US will be responsible for all technical aspects of the system during the
    demonstration. The user terminal operations in the additional spectrum requested will be
    closely monitored by the Inmarsat Network Operations Center (NOC) and the engineering
    team associated with the demonstration. It is expected that the Antennas will be used starting
    16 October through 4 November – this time period will allow testing prior to the demonstration.

    II.    ISAT US SEEKS AUTHORITY TO OPERATE AERO TERMINALS
           ON ADDITIONAL FREQUENCY BANDS (29.375-29.5 GHz/19.575-
           19.7 GHz)

             ISAT US is already licensed to operate the Antennas in the 29.5-30 GHz (uplink) and
    the 19.7-20.2 GHz (downlink) bands. Therefore, ISAT US seeks authority to operate the
    Antennas in the following additional frequency bands: 29.375-29.5 GHz (uplink) and
    19.575-19.7 GHz (downlink). ISAT US requests this authority on a non-interference and
    non-protected basis. ISAT US requests a waiver of the U.S. Table of Frequency
    Allocations, 3 as necessary, to allow the proposed FSS STA operations in the 19.575-19.7
    GHz frequencies. Grant of a waiver would serve the public interest because it would allow
    demonstration of important services through the I5F2 satellite to potential customers and
    facilitate further deployment of satellite broadband to end users. As discussed below, grant
    of the requested waivers would not undermine the policy objective of the rule, as the
    primary operators in these bands under the U.S. Table would be protected from harmful
    interference.

           For clarity ISAT US provides the following technical parameters for the additional
    frequencies requested:

    EARTH-to-SPACE:
    Transmit Frequencies: 29.375-29.5 GHz
    Transmit Polarization: RHCP
    Maximum EIRP: 50.4 dBW
    RF Modulation: 8 APSK (max)
    Minimum Elevation for Transmission: 5 degrees (on the ground)
    Emission Designator: Same as those licensed in Call Sign E140114 for 29.5-30.0 GHz band.
    Antenna Gain MCS8000: 37 dBi
    Antenna Gain MCS8200: 39.8 dBi

    SPACE-to-EARTH:
    Receive Frequencies: 19.575-19.7 GHz
    Receive Polarization: LHCP
    Maximum Spacecraft EIRP: 54dBW
    RF Modulation: 16 APSK
    Azimuth Range: 360 degrees
    Emission Designator: Same as those licensed in Call Sign E140114 for 197-20.2 GHz band.
    Antenna Gain MCS8000: 32.7 dBi
    Antenna Gain MCS8200: 36.8 dBi

    HCP Beam: Center at 25.4º N and 76.2º W with a beam radius of 0.8 degrees

Description of Operations
During the week of October 16-21, the Antennas will be tested using the HCP Beam at the
Satcom Direct facility located in Melbourne, Florida. The specific location of the Satcom
Direct facility is: 28.26º N, 80.69º W. After this period of time, operations will then transition
to flight-testing of the Antennas using the Honeywell Boeing 757 aircraft. The aircraft will be
flying routes leaving from and returning to Orlando International Airport (MCO). The flight
path will take an easterly route out of MCO out over the Atlantic Ocean and then back to
MCO.

    Duration of Communications: approximately 19 days

    24 Hour Point of Contact during the STA: Inmarsat Network Control +44 207 728 1616

    Space Station Coordination

       The operations under this STA will operate with one of the Global Xpress High
Capacity (HCP) spot beam, the technical parameters of which were included in the Inmarsat
Mobile Networks, Inc application for market access and incorporated by reference in this
request. 4 During the proposed operations the HCP beam will be centered at 25.4º N and 76.2º
W.

           The coordination of communications for the use of the additional frequencies (29.375-

    29.5 GHz/19.575-19.7 GHz) with the I5F2 spacecraft at the 55º W.L. orbital location with
    existing spacecraft operators during the demonstration is the responsibility of Inmarsat and
    ISAT US. Inmarsat has completed coordination with potentially affected satellite operators,
    and operations under the STA will be consistent with these agreements. In accordance with
    normal industry practices, communications with other operators will be kept open in the
    period leading to and throughout the demonstration activities, to ensure that the
    demonstration will be conducted on a non-interference basis.

           The Commission’s Ka-band band plan identifies the 29.375-29.5 GHz band for GSO
    FSS and the Antennas will be operated consistent with the already licensed parameters. As
    demonstrated in the Inmarsat Market Access Application, the proposed STA operations in the
    19.575-19.7 GHz frequencies are unlikely to cause interference into fixed service operations
    that are co-primary in that band segment. The Antennas will be receiving in these bands and
    therefore will not cause interference to other users. Moreover, as the Commission
    acknowledged in granting market access for the I5F2 spacecraft, the space-to-Earth
    transmissions comply with the pfd limits established under Article 21 of the ITU Radio
    Regulations established to protect all fixed earth stations. 5

                                   *       *      *       *       *

            Grant of the requested STA will serve the public interest, convenience and necessity
    because it will enable ISAT US to conduct demonstrations of the Global Xpress capabilities
    using the Inmarsat-5 F2 spacecraft, within technical parameters consistent with the
    parameters described herein using the identified Antennas, without creating any risk of
    harmful interference. ISAT US respectfully requests that the Commission grant STA
    beginning 16 October 2016 for a period of 19 days.
