Exhibit 1 Reason for Special Temporary Authority and Description of 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, 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 under a variety of constraints and scenarios. Special Temporary Authority (STA) with respect to repeating GPS signals is requested to support the communications requirements for the crash testing of vehicles. The crash test facilities at Milford Proving Grounds are uniquely equipped to conduct the testing for type approval that is required by new crash safety regulations in one of GM’s target jurisdictions. This type approval testing is tentatively scheduled to begin April 27, 2015. The crash testing at Milford Proving Grounds occurs indoors, and therefore the roof of the facility blocks GPS signals from reaching the test vehicles. GM requests authority to install a GLI-Metro-G Unit by GPS Source inside the crash test building in order to successfully complete the required testing. GPS signals will be received and re-transmitted into the building for the limited purpose of type approval, which will allow GM to certify its vehicles comply with new crash safety regulations. GPS Source previously received experimental license WD2XTF to operate its GPS equipment in the United States; GM is submitting the same emission calculations in support of this application. FCC approval is requested in advance of April 27, 2015 so that GM may timely conduct testing related to the new regulation. Objectives GM seeks to accomplish the following objectives: 1. Transmission of GPS signals inside the crash testing building. 2. Conduct tests to certify that GM’s vehicles satisfy the applicable crash safety regulations. 3. Test equipment implementation and troubleshoot problems in a controlled environment. Contribution to Radio Art Active crash notification reporting systems are under development and being deployed in the marketplace. This project is necessary to validate the effectiveness of the developed crash notification system. Such systems have the ability to immediately notify emergency personnel when a crash occurs, which saves time and helps prevent the loss of life in emergency situations. 1

When used in conjunction with an active GPS/GLONASS receive antenna, it will pass » Use for any GNSS retransmission GPS+GLONASS signals inside a building, hangar or any structure where signal is not accessible. application It can be used in an automated test environment or in a shielded room that needs GNSS signal. GLI—METRO—G has the unique benefit of allowing selection for the power control between signals. OPTIONS A user can easily decide which signal output the GLI—METRO—G will use to control signal power: » Waterproof GPS+GLONASS, GLONASS only or GPS only. This reduces the need for multiple antennas, » L1 Only vs. L1/L2 Filtering receive devices and multiple antenna runs, while lowering maintenance and installation costs. » Multiple Connector Types AUTOMATIC SIGNAL LEVEL CONTROL » Power Always ON or Power The GLI—METRO—G employs an automatic control to maintain the set output signal level, ON/OFF regardless of the uncertain loss or gain in the receive antenna cable network. Derived from high performance systems for military applications, this device allows precise determination over effective radiated power (ERP) levels, regardless of the uncertain loss or gain in the receive antenna cable network. It will automatically condition the signal and prevent changes in performance. BUILT—IN TROUBLESHOOTING The GLI—METRO—G will identify and isolate the following: — Oscillation condition — Internal component failure — High gain — Less than four satellites — Low gain — No satellites with adequate signal — Short/Open circuit (call for complete list of conditions) *GLI—Metro—G offers support for present and future GNSS @,‘s’? signals, including Galileo, ensuring operation with future ®. m/ devices. hi www.qpssource.com L5 0 UR CE ors LIVE INSIDE GPS Source, Inc. | techsales@gpssource.com | (866) 289—4777 toll free (in U.S.) | +1 (719) §61—9520 °100 Rev C ane 180 01 Certfed
