Exhibit 1 – Overview and Explanation

Overview:
U U Raytheon Intelligence, Information and Services (Raytheon) is filing this
application for use of a GPS re-radiation system in its facility at 9020 South Sandy Parkway,
Sandy, Utah. This facility utilizes GPS for positioning information and timing technologies for
test equipment for ground station receivers. The GPS re-radiation system is required for the
testing of GPS technologies that are embedded into the communications systems that Raytheon
is developing in this lab.

General compliance with NTIA section 8.3.28: set forth below are Raytheon’s responses to the
requirements of 8.3.28 as those answers apply for this location.

For any questions about this application, please contact Brian Kavalar, Raytheon IIS Spectrum
Manager, 317-517-998, brian_r_kavalar@raytheon.com

Compliance with the Requirements of NTIA Manual Section 8.3.28

1. Individual authorization is for indoor use only and is required for each device at a
specific site.

This GPS re-radiation system will be installed indoors in a laboratory with access that
is limited to Raytheon authorized personnel only.

2. Applications for frequency assignment should be applied for as an XT station
class with a note indicating the device is to be used as an “Experimental RNSS
Test Equipment for the purpose of testing GPS receivers” and describing how
the device will be used.

Raytheon requests the assistance of the FCC and NTIA to properly classify the
frequency authorizations.

3. Approved application for frequency assignment will be entered in the GMF.

Raytheon requests the assistance of NTIA and the FCC in entering this data into the
GMF.

4. The maximum length of the assignment will be two years, with possible renewal.

Raytheon is seeking an authorization for two years, and it will seek renewals when
required.

5. The area of potential interference to GPS reception (e.g., military or contractor
facility) has to be under the control of the user.

The proposed installation will be inside the Raytheon facility at Sandy, Utah. Access to
the facility is limited to Raytheon personnel and limited authorized visitors. The
building is a secure facility, and no unauthorized visitors can enter.

6. The maximum equivalent isotropically radiated power (EIRP) must be such that
the calculated emissions are no greater than -140 dBm/24 MHz as received by an
isotropic antenna at a distance of 100 feet (30 meters) from the building where
the test is being conducted. The calculations showing compliance with this
requirement must be provided with the application for frequency assignment and
should be based on free space propagation with no allowance for additional
attenuation (e.g., building attenuation.)

Link Budget: The link budget for the L1/L2 re-radiation is attached to this exhibit, and it
shows the calculations applicable to this proposed installation of a GPS re-radiation
system.

Location in building: The re-radiation device will be installed inside Raytheon building at
Sandy, Utah. The installation is on the third floor of the building. The attached link
budget shows that the signal strength at 100 feet from the re-radiating antenna is below
-140 dBm/24 MHz. Thus, the signal strength at 100 feet from the building is going to be
significantly lower still, but Raytheon wanted to ensure that the signal strength was
attenuated to the point that there would be no chance of interference.

7. GPS users in the area of potential interference to GPS reception must be notified
that GPS information may be impacted for periods of time.

Raytheon will post signs in the lab where the re-radiation system is installed alerting
those in the area that there are GPS re-radiation systems in use in that area.

8. The use is limited to activity for the purpose of testing RNSS equipment/systems.

Raytheon is requesting authorization to use a re-radiation system specifically for testing
of GPS systems on its products.

9. A “Stop Buzzer” point of contact for the authorized device must be identified and
available at all times during GPS re-radiation operation of the device under any
condition.

The Stop Buzzer point of contact for all these devices is:

Mark J. Murray, Raytheon IIS

703-869-6549 (cell)

Mr. Murray can initiate shut off the GPS re-radiation system at any time.
