                                                                                      Exhibit 1

                                PUBLIC INTEREST STATEMENT

1.       Introduction

        DRS Signal Solutions, Inc. (“DRS SSI”) respectfully requests that the
Commission grant a two year experimental license to permit DRS SSI to operate at the location
specified in the application.

2.       Purpose and Nature of the Operation

        DRS SSI, headquartered in Gaithersburg, MD, is world leader in high-performance
Signals Intelligence (SIGINT) tuners and receivers covering frequency ranges from HF through
SHF, data recording & collection, software definable radios, and geo-convergence systems. The
company has served the Intelligence Community for more than fifty years, with cutting edge
Size, Weight, And Power (SWAP) reduction, world class microwave technology, and tools to
search, intercept, analyze, and record signals.

        The purpose of this experiment is to demonstrate the performance of DRS SSI’s
Transceiver under data/voice transmission and detection in a real world environment. This
experiment will help to identify potential pitfalls in the design and lead to corrective actions
before the product is released to production.

         DRS SSI respectfully requests waiver of the Station ID rule.

3.       Transmitting Equipment

                                                                                    Experimental?

4.     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:

        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
transmitters will be radiating low levels of RF power while viewing targets of interest. Average
levels will be no more that 25W, transmitting for a few hours per day. In the off state, no
measurable power will be radiated. In fact, there may be extended periods of non-operation
during the authorized period.

5.     Stop Buzzer

        DRS SSI advises that the following will be available by wireless telephone and will act as
a “stop buzzer” if any issues regarding interference arise during testing:

       Gaithersburg MD Operations – Song Phommachanh – 240-644-3867

       Cary, NC Operations – Clark Pope – 919-815-7345

For the foregoing reasons, DRS SSI respectfully submits that approval of this application is in
the public interest, convenience and a necessity.
