Interference Analysis Report An Assessment of the Impact of Radiolocation Systems Operating in 3.1-3.7 GHz Band on Fixed Satellite Services Earth Station Receiver Prepared for SES Americom, Inc. TRANSMIT-RECEIVE EARTH STATION (13.0 METER) FCC CALL SIGN: KB27 Site Name: Moorpark, California Prepared By August 5, 2013 19700 Janelia Farm Blvd.• Ashburn, Virginia 20147 USA • 703.726.5500

1.0 Introduction Interference calculations were performed to determine the potential for in-band and out-of-band interference from Radiolocation Systems operating in the 3.1 to 3.7 GHz band1. The geographical positions and operating parameters of these systems was derived from NTIA Document TR-99-3612. 2.0 Radiolocation Systems in the 3.1 – 3.7 GHz Band High powered mobile and fixed radar systems operated by the Federal Government operate in the 3.1 – 3.7 GHz band. These radars are used to search for, and track, near-surface and high-altitude airborne projectiles, sea surveillance and airborne objects. The NTIA report referenced above has identified the locations for two types of systems: land-based and shipboard based. Also included in the report are the operating characteristics of these radars. There are two prevalent types of shipboard radars, denoted as type A and Type B, and one type of ground-based radar. An Airborne System radar is also specified. This analysis will concern itself with interference from the ground based and shipboard based radars based upon the relative operating positions and parameters specified in the NTIA report. A summary of the operating parameters for the shipboard and ground based radar systems is shown below: Table 1 – Technical Characteristics of 3.1-3.7 GHz Radiolocation Systems Characteristic Shipboard System A Shipboard System B Ground Based System Modulation P0N Q7N P0N Tuning Range (GHz) 3.5-3.7 3.1-3.5 3.1-3.4 Peak transmit Power 1 4 0.12 (MW) Pulse Width (µsec.) 1.0 3.5-51.2 10.75 Pulse Repetition Rate 1.125 0.152-6.0 2793.3-5050.51 (kHz) Duty Cycle (%) 0.001 0.8-2.0 0.041 Transmit 3-dB 4,16.6 4 1,10 Bandwidth (MHz) Antenna Type Reflector Phased Array Phase Scan Array Antenna Mainbeam 32 42 36 Gain (dBi) Antenna Centerline (m) 46 20 46 1 This report is being provided as required under Footnote US 245. 2 National Telecommunications and Information Administration, U.S. DEPARTMENT OF COMMERCE, NTIA Report TR 99-361, TECHNICAL CHARACTERISTICS OF RADIOLOCATION SYSTEMS OPERATING IN THE 3.1-3.7 GHz BAND AND PROCEDURES FOR ASSESSING EMC WITH FIXED EARTH STATION RECEIVERS, (December 1999).

4.0 Interference Calculations The interference was calculated into the earth station receive system for both in-band and out-of-band interference. The interference power level was calculated using the formula below: Pr = Pt + Gt – FSL – OHLOSS + Ges – LLt - LLes Where: Pr : Interference power level received at victim earth station, in dBW Pt: Transmitter power of Radiolocation system, in dBW Gt: Gain of Radiolocation transmit system, in dBi FSL: Free Space Loss between radiolocation system and earth station, in dB OHLOSS: Over-the-Horizon losses between radiolocation system and earth station, in dB Ges: Horizon gain of the earth station toward radiolocation transmitter, in dBi LLt: Line losses of the radiolocation system, in dB (assume 2dB per NTIA report) LLes: Line losses of the earth station system, in dB (assume 0 dB unless known) This interference power level was then compared to in-band and out-of-band interference criteria. The in-band criteria was developed using ITU and FCC recommendations3. The out-of-band interference criteria was developed using the following: The earth station’s low –noise amplifier front-end overload criteria of was determined using the following calculations: T=C–G Where: T = input threshold at which front-end overload occurs, dBW C = output 1 dB gain compression point of the LNA, typical -20 dBW G = Gain of the LNA, dB For the purposes of this report it was assumed that the low-noise amplifier would not provide any out-of-band frequency rejection, thus no Frequency Dependent Rejection values based upon any RF selectivity, such as pre-LNA filtering or inherent LNA filtering, have been assumed. The maximum level of interference includes the input saturation threshold value minus a 10 dB output backoff value to consider in operation levels The maximum interference power receive, Pr, allowable then becomes: Max Pr > T - IPBO For a 65 dB gain LNA this value is -95 dBW. In the absence of manufacturer LNA/LNB specifications the following typical values have been used: T = -95 dBW C = -20 dBW G = 65 dB The propagation model to determine the over-the-horizon loss is the NSMA OH-Loss model4. When the propagation link is very lengthy, over 250 miles, an estimated OH-loss using a rounded earth modeling value has been used. 3 FCC Rules 47CFR25.251 by reference ITU Radio Regulations Appendix S7. 4 National Spectrum Managers Association has developed an industry accepted version which incorporates NBS Tech Note 101.

5.0 Summary of Results The summary calculations are shown for all shipboard based and land based systems in Tables 4 through 8 below. Whenever Radar A and B are possibly in use, the interference calculations have assumed the higher powered systems (Radar B). The antenna elevation for the Ground Based systems was assumed to be 46 m even though it was not specified in the NTIA report. Interference Analysis Report for Moorpark, California

6.0 Conclusions Calculations were performed to assess the electromagnetic compatibility (EMC) between the radars listed below and adjacent-band FSS earth station receiver at Moorpark, California. Interference assessment for Earth Stations Operating at 3625 - 3700 MHz at Moorpark, California site identified 4 cases of In-band potential interference. The applicant is aware of this potential for interference and will work with the Government Users to mitigate the problem.
