Application Narrative for Proposed Special Equipment Program

Description of General Motors Research Corporation Operations
         The General Motors (GM) Milford Proving Grounds is a GM facility in Milford, Michigan. The
campus is home to 4,000 GM Engineers and Technicians and has been the premier GM testing facility
since 1924. Many types of validation testing, including vehicle crash testing and telematics system
testing, are conducted at the Milford Proving Grounds. Ever-changing crash safety regulations, and
differences between such regulations from one jurisdiction to another, require GM to conduct vehicle
crash testing and telematics system testing under a variety of constraints and scenarios.

         General Motors Research Corporation (GMRC), a wholly owned indirect subsidiary of GM,
requests a two-year experimental license to repeat GPS signals to support the communications
requirements for the crash testing of vehicles and telematics systems. The crash test facilities at Milford
Proving Grounds are uniquely equipped to conduct verification testing of telematics systems. Although
GMRC is currently operating a GPS re-radiator pursuant to Special Temporary Authority (STA), it would
like to expand the testing to include vehicles for additional target jurisdictions and telematics systems.

        The vehicle crash and telematics system testing at Milford Proving Grounds occurs indoors, and
therefore the roof of the facility blocks GPS signals from reaching the test vehicles. GMRC has already
acquired an experimental license to operate one GLI-Metro-G Unit by GPS Source inside the crash test
building under the call sign WH2XXR. However, approval for five (5) more GLI-Metro-G units is required
to ensure coverage in the entire crash test facility and to successfully complete the required testing. In
addition a change to the output power of the existing GLI-Metro-G Unit is proposed.

        GPS signals will be received and re-transmitted into the building for purposes of type approval,
which will allow GMRC to certify that vehicles comply with new crash safety regulations, and the testing
of vehicle telematics systems. The attached emission calculations demonstrate that the GPS Source
equipment complies with the Commission’s emission limits for GPS re-radiators.

Objectives
        GMRC seeks to accomplish the following objectives:
        1. Coverage of our testing facility with GPS and GLONASS radio signals.
        2. Ability to conduct tests according to regulatory requirements.
        3. Ability to test equipment implementation and troubleshoot problems in a controlled
           environment.

                                                                                                          1


Contribution to Radio Art
        Verification of the development of active crash notification reporting systems is beginning.
Implementation of this project is necessary in the validation of the developed crash notification systems.
These systems will have the ability to notify emergency personnel immediately when a crash occurs,
which saves time and thus saves lives in moments when time is critical.
