FOR INFORMATION f&‘“ ‘0«@%‘ *4 W : UNITED STATES DEPARTMENT OF COMMERCE % & National Telecommunications and “'«5 $ Information Administration *rares 0f Washington, D.C. 20230 May 3, 2005 Doc. 34350/1 Ref. Doc. 34284/1 TO: Executive Secretary, IRAC SUBJECT: Addition of Section 8.3.28, USE OF DEVICES THAT RE—RADIATE SIGNALS RECEIVED FROM THE GLOBAL POSITIONING SYSTEM, to the NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management. I concur with the recommendations of the NTIA Staff and the members of the IRAC. In Recognition of the need for federal and non—federal users need to operate devices that re—radiate received signals from the Global Positioning System (GPS) in order to test GPS receivers, Section 8.3.28 is being added to the NTIA Manual. Section 8.3.28 will establish the appropriate regulatory mechanism for considering such systems to ensure that general GPS use will be protected. NTIA is prepared to support requests from that FCC that meet these criteria. Please ensure that Section 8.3.28 is added in the next revision of the NTIA Manual of Regulations and Procedures for Federal Radio Frequency Management. Fredrick R. Wentland Associate Administrator Office of Spectrum Management Attachment

IRAC RECOMMENDED ADDITION TO CHAPTER 8 TO AUTHORIZE GPS RE—RADIATORS UNDER SPECIFIC CIRCUMSTANCES ADD 8.3.28 USE OF DEVICES THAT RE—RADIATE SIGNALS RECEIVED FROM THE GLOBAL POSITIONING SYSTEM Except as otherwise authorized under 7.14, federal agencies may, under the following conditions, operate devices that re—radiate signals received from the Global Position System (GPS). 1. Individual authorization is necessary for each device at a site—specific location. 2. Applications for frequency assignment should be applied for as an XT station with a note indicating that the device is to be used as an "Experimental RNSS Test Device for the purpose of testing stand—alone GPS receivers or GPS receivers that are an integral component of an equipment under test". Approved applications for frequency assignment will be entered in the GMF. O i h w The maximum length of the assignment will be two years, with possible renewal. The operation must be at specified fixed location and mobile operation is not authorized. The area of potential interference to GPS reception (e.g., military or contractor facility) has to be under the control of the user. The maximum equivalent isotropically radiated power must be such that the calculated emissions are no greater than —140 dBm/24 MHz 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 building attenuation. GPS users in the area of potential interference to GPS reception must be notified that GPS information may be impacted for periods oftime. The use is limited to activity for the purpose of testing RNSS equipment/systems . 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.
