                       REQUEST FOR LIMITED 7 DAY STA
                   FROM APRIL 21, 2012 THROUGH APRIL 27, 2012
                TO CONDUCT A DEMONSTRATION FOR THE US ARMY

       1.      Introduction

       By the instant application (“Application”), DRS Sustainment Systems, Inc. (“DRS SSI”)
requests that the Commission grant a very limited seven day special temporary authority (“STA)
to permit DRS SSI to operate the facilities (the “Facilities”) specified in the instant application to
conduct a demonstration for the US Army. .

       2.      Purpose and Nature of the Operation

        This STA is requested for the same facilities that were recently authorized under
File No. 0009-EX-ST-2012, but at a new location (Inyokern Airport), to allow DRS SSI to
conduct a demonstration of DRS SSI’s ATS-100 device for the US Army, at the request of
the Army. This experiment will demonstrate the ATS-100’s ability to stimulate 160th
Special Ops rotary winged aircraft. DRS requests grant of a very limited seven day STA
for this new location, from 4/21/2012 through and including 4/27/2012,1 with the same
terms and conditions imposed for the prior grant under File No. 0009-EX-ST-2012.

      DRS SSI received the request to conduct this demonstration only three days ago,
and has acted as quickly as possible to prepare and submit this request for Commission
authority. A separate Request for Expedited Processing has been submitted along with this
Application. The Army POC for this demonstration is:

                               Jason Grimes – Aircraft Survivability Equipment Specialist:
                               Bldg 7280-3
                               Night Stalker Way
                               Ft. Campbell, KY 42223
                               Tel: (270) 798-5697

        The Facilities DRS has designed related to the instant application provide a highly mobile
capability for aircraft maintenance crews to conduct diagnostics and system verification in the
field so that U.S. military men and women can have the confidence to focus on the mission at
hand. DRS’ immediate effort to demonstrate the Facilities is intended to save lives in a rapidly
evolving surface to air missile (SAM) threat environment. The impact on military operations
when there is a lack of Aircraft Survivability Equipment (ASE) test capability can be
devastating. This vulnerability was revealed by the defeat of Soviet forces in Afghanistan which
was largely enabled by SAMs in the hands of the Mujahedeen. While such a threat has been
largely contained by control over arms sales, the recent collapse of the Libyan regime resulted in
the release of over 5,000 Russian SAMs into uncontrolled markets. This places US aircrews and
passengers in Afghanistan and in other regions in immediate threat when their ASE readiness
cannot be verified before flight operations in hostile territory.

 The demonstration itself is planned to commence April 23, 2012, but grant is requested as of
April 21, 2012 to permit pre-demonstration testing and set-up to ensure a successful
demonstration for the US Army.
                                                  1


        This particular experiment will involve ground-based mobile transmissions to support the
development and testing of DRS SSI’s ATS-100 device, a hand-held instrument used to test the
Radar Warning Receivers (RWRs) of military aircraft, fixed and rotating wing. In appearance
and mode of operation the ATS-100 resembles a radar ‘speed gun’ as used by the police. An
RWR detects radar signals from hostile ground or airborne sources and alerts the pilot that his
plane is potentially exposed to the enemy. Transmissions under the requested STA will involve
pointing the ATS-100 device at an aircraft on the ground with a series of simulated radar
transmissions to ensure that the correct warning is triggered in the cockpit. The ATS-100 device
will typically be operated at a distance of 1-10m from the aircraft, and the test transmissions will
typically be repeated at four points around the aircraft to ensure that the pilot receives correct
information about the direction of the threat.

       3.      Signal Characteristics/Modulating Signal/Bandwidth

        The signal can be continuous (CW) or pulse modulated. In pulse mode the modulating
signal is a pulse train with pulse width and repetition rate programmable. The repetition rate can
be between 1Hz-1MHz and with pulse widths of between 50ns-100us. Repetition rates and pulse
widths are selectable in a 1,2,5,10,20,50 etc. sequence. There are 182 valid combinations of
repetition rate and pulse width for each RF frequency setting. (Invalid combinations arise when
the pulse width exceeds the time between pulses). In all cases the RF signal is simply gated on
and off – no AM or FM modulation is applied and the signal carries no information.

        The maximum bandwidth requirement occurs when the shortest duration pulse width is
used for modulation. Under these circumstances (i.e with 50 ns pulse width) the bandwidth is
approximately 20 MHz (10 MHz either side of the carrier). When no pulse modulation is
selected (CW operation) the transmission is effectively a spot frequency.

       4.      Directionality of Antenna

       The instant form requests directionality/information information for “directional
antenna[s] (other than radar)”. Because the antenna (a horn-type) is a radar system, a “No”
answer has been inserted on the form. However, for the purpose of completeness, the following
information is provided with respect to the radar signal to be used in this experiment:

       5.       Comment Regarding Emission Designator
       The ATS-100 operates in two modes, either Continuous or Pulse modulation. When
operating in Continuous mode, the designator is clearly “P” as there is no modulation. However,
when operating in Pulse mode, there is modulation, however no information is being carried.
DRS SSI could not identify a third symbol for the designator which clearly described the ATS-
100 Emissions while in Pulse mode operation, therefore DRS SSI was left to assign the “X”
designator for the second symbol.

        6.      Interference Mitigation
        DRS SSI is well aware of its obligations under Part 5 of the Commission’s rules to avoid
interference to co-channel licensees in non-experimental services, and will take all steps to
ensure compliance with this obligation. With respect to interference mitigation, DRS SSI
advises as follows:

       -    The maximum ERP levels are very low, with a maximum ERP of 180 mW between
            3-5 GHz; 600 mW between 8-12 GHz; and 220 mW between 14-16 GHz.

       -    Operation of the requested Facilities will not be continuous. Rather, authority for
            only sporadic operation of the Facilities is requested during the authorized
            timeframe. The ATS-100 will issue highly intermittent transmissions of very short
            duration, which will significantly limit the potential for interference to authorized
            users. DRS will typically run 4 – 10 tests per aircraft tested. Each test will consist of
            transmitting for up to 10 seconds. If the aircraft has no functional problem, only four
            tests will be necessary for each plane. If the aircraft does appear to have a problem,
            we will run multiple tests (at different power levels), but not more than 10 test will
            occur per aircraft. In the off state, no measurable power will be radiated. In fact,
            there may be extended periods of non-operation during the authorized period, while
            other non-RF transmission aspects of the experiment are conducted.

        -   DRS SSI understands that FAA (or other stakeholders) may require certain limited
            azimuth and/or elevation blanking in order to ensure that the proposed Facilities do
            not pose a threat of interference to adjacent emitters. Accordingly, this is to confirm
            that the subject radar device has such blanking capabilities and that DRS SSI stands
            ready to work with FAA to identify any reasonably necessary azimuth and/or
            elevation restrictions for the system.

       6.      Stop Buzzer

       DRS SSI hereby advises the Commission that the following personnel will act as “stop
buzzers” if any issues regarding interference arise during testing:

       Primary: Phil Niosi – 321-368-0768
       Alternate: Mario Saracino – 314-553-4630
