                                                                                 Exhibit 1

                          PUBLIC INTEREST STATEMENT

1.     Introduction

       By the instant application (“Application”), Leidos, Inc. (“Leidos”) requests that
the Commission grant a 6-month Special Temporary Authority – from 5/30/2015-
11/30/2015 - to operate the facilities (the “Facilities”) specified in the Application.

2.     Purpose and Scope of Operation

        Leidos is a leading provider of scientific, engineering, systems integration and
technical services and solutions. Leidos’s Surveillance and Reconnaissance Group
provides maritime intelligence, surveillance, and reconnaissance (ISR) as well as airborne
reconnaissance, with an emphasis on mission capability integration and services and
products for the military space domain. Working in high-risk environments, SRG
employees leverage full spectrum phenomenology, including sensors and signature
detection, to deliver superior technology-driven, mission-responsive ISR collection and
associated processing, exploitation, and dissemination solutions to support our nation's
security in the space, air, land, and maritime domains. The testing for which authority is
sought in the instant Application is a critical part of the manufacture and delivery of
systems designed to support the Warfighter in ISR activities.

        The specific purpose of the system for which authority is requested is described at
Exhibit 3, which is subject to Leidos’s “Confidentiality Request” attached to the
Application at Exhibit 2. As a general matter, the instant Application seeks Commission
authority to operate the specified Facilities within a 100 km radius of two specified
centerpoint locations. Similar parameters were previously authorized by the Commission
under call sign WG2XGY to SAIC (now known as Leidos), which Leidos hopes will help
the review process, and in this regard this Application seeks authorization at much lower
power levels than previously authorized.

3.     Other Technical Information

       Single Aperture:       CW transmit power is 0.10 Watts
                              Attenuators are also available to further reduce transmit
                              power
                              Gain is 16.3 dBi at 9.5 GHz
                              Beamwidth of transmitting scalar feed horn antenna is
                              30.3° at 9.5 GHz for vertical, 29.3° at 9.5GHz for
                              horizontal


4.     Interference Mitigation

        Operation of the requested Facilities will not be continuous. Rather, authority for
only limited and sporadic operation of the Facilities is requested during the authorized
timeframe, i.e., at any given authorized location, the cumulative period of operation in
any given 24 hour period will be no more than 8 hours. In the off state, no measurable
power will be radiated. In addition, only one unit will be operated at any given time at
any of the specified locations in the Application.

        The transmit antenna has a wide beamwidth but will be fixed in pointing direction
rather than rotating during transmission.

        Leidos 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 system has such blanking capabilities and that Leidos stands ready to work
with FAA to identify any reasonably necessary azimuth and/or elevation restrictions for
the system.

        Authority is requested for only limited and sporadic operation of the Facilities
during the authorized timeframe. The majority of operations of the Facilities will be
conducted inside the laboratory. When out doors, the operation will be sporadic, not
continuous. 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.

       Based on the location of the experiment, the technical parameters of the operation,
and the manner in which the experiment will be conducted, interference to any co-
channel or adjacent channel operations (including for example radio astronomy) is
mitigated.

5.     Power

       The ERP indicated in the application is on the order of 10s of Watts, however the
maximum power available into transmit antenna is under 0.5Watt and will be attenuated
to 100s of mW given the required link budgets to complete our experiments. The
Equivalent or Effective Radiated Power (ERP) is 4W.

6.     Prevention of Interference

       Leidos hereby advises the Commission that Leidos’s King-Sang Chan will
personally monitor the experiments for which authority is requested, and will act as a
“stop buzzer” if any issues regarding interference arise during testing. Mr. Chan can be
reached on his cell phone at 703-304-0674
