Exhibit 1—Particulars of Operation The experimental license is being requested to cover Airborne Mobile Earth Stations (MES) operating in the Aeronautical Mobile Satellite Service (AMSS) mode of Globalstar®" service, and will not cover any cellular—mode service. For the Airborne MES mode: a) Frequency of operation: Transmit band of 1610 to 1621.35 MHz, receive band of 2483.5 to 2500 MHz. Globalstar®" terminals are designed with the capability to operate in the entire 1610—1626.5 MHz band; however, in the U.S. these MES‘ will operate only in the 1610—1621.35 MHz range, consistent with the FCC license held by L/Q Licensee. Any references in this application to the 1610—1626.5 MHz band apply to the MES capability only. When operating in the Airborne MES mode, the Globalstar"" terminals transmit in one of nine 1.23 MHz wide CDMA channels within 1610—1621.35 MHz frequency range. Similarly, when operating in the MES mode, the Globalstar®" terminals receive in one of thirteen 1.23 MHz wide CDMA channels within 2483.5 to 2500 MHz frequency range. b) Antenna Polarization: Left hand circular c) Emission Designator: 1M23G7ZW d) Maximum EIRP: The maximum EIRP is dictated by the maximum available transmitter power for a particular radio and its peak antenna gain. As a conservative estimate, no factor is taken for time averaging of the variation in output power due to data rate changes and power control commands. The EIRP density is the EIRP divided by the channel! bandwidth of 1.23 MHz and further corrected for the required 4 kHz bandwidth. e) Maximum EIRP density Globalstar®" Mode Radio Type Max T’f Power Peak Aqtenna Max EIRP (e) Max _EIRP and Mode Available Gain (aBw Density (dBW) (dBic or dBi) (dBW/4 kHz) Airborne 4.0 3.0 7.0 —17.9 Page 1

Exhibit 1—Particulars of Operation f) Description of Modulation: The Globalstar" MES transmitter realizes direct sequence spreading at a chip rate of 1.2288 MHz. Baseband filtering is implemented as shown in the figure below. In phase and quadrature, signals are combined to form OQPSK modulation. Baseband Filter Frequency Rtsponsev [ Tfl \\ ~1 \ 307.2 614.4 9116 12288 1336 wa2 Baseband Filter Frequency Response Power is continuous for 9600, 4800, and 2400 bps modes and is spread by a direct sequence with a chip rate of 1.2288 MHz. The output power changes in accordance with the data rate for the frame. Page 2

Exhibit 2—Globalstar Application Applicant‘s Qualifications and Proposed Experiments Globalstar L.P. the manager of the Globalstar non—geostationary MSS Above 1 GHz system, is applying for an experimental license to conduct tests associated with system operation. Globaistar is a Delaware, partnership, and is ultimately controlled by Loral/Qualcomm Partnership, L.P., the parent of L/Q Licensee, Inc. (LQL). LQL holds the license for the Globalstar system‘. The Globalstar system has been authorized for construction, launch and operation in the 1610—1621.35 MHz and 2483.5 and 2500 MHz bands. The system is presently operational and it consists of 48 technically—identical satellites orbiting the Earth in a circular orbit plus four in—orbit spares. As part of the pre—operational AMSS program, the User Terminals are required to be field tested on aircraft to validate the performance prior to the start of this new service for Globalistar. Experimental user terminals to be operated under this authorization will be used throughout the USA to validate their RF performance parameters in conjunction with those of the Gateway and satellite constellations. The program of tests will be conducted over the next two years to ensure that the system will have been successfully deployed and tested. Conclusion Grant of this application will permit Globalstar to conduct a thorough operational validation of the airborne user terminals and perform thorough Globalstar"" system level tests in conjunction with the Gateway and Satellite constellation. This test is essential to the success of the Globalstar"" network operation and enables this service to commence satisfactorily as authorized by the Commission in its grant of the Globalstar"®" license to LLQ Licensee, Inc. The information obtained from the tests will help Globalstar implement the system on the current schedule and commence commercial AMSS in approximately 6 months. The public interest would be served by grant of this application. These tests will provide useful information on the performance of the system, which will promote the development and delivery of the planned global Aeronautical Mobile—Satellite Services to the public. ‘ See Loral Qualcomm Partnership, L.P., 10 FCC Red 2333 (1995) (authorizing constellation and use of service links); L/Q Licensee, Inc. 11 FCC Red 16410 (1996) (authorizing the use of feeder links).
