JUN #2 ‘@8 11:10 FR 450 MISSION SUCS PROJ3A1 286 1724 TO 918187069431 P. 0208 A Coordination Agreement Between the National Aeronautics and Space Administration (hereinafter "NASA") _ and Row44, Incorporated (hereinafter "Row 44") for Operation of the Row AMSS in the 14.05 — 14.47 GHz—Band Row 44 seeks to license and operate acronautical mobile—satellite stations (AMSS) over the Continental United States (CONUS) on a secondary basis in the 14.05 to 14.47 GHz FSS band. The AMSS terminals are part of the Row44 communications system aboard general aviation and commercial aircraft using transponders in the Geostationary Satellite Orbit (GSO) are. This Coordination Agreement has been prepared in compliance with the rules of the Federal Communications Commission (FCC) and the recommendations of the member states of the International Telecommunication Union (ITU) following the World Radio Communication Conference WRC—03. 1. Overview The 14.0 — 14.5 GHz—band has been allocated to the mobile—satellite service. nowincluding acronautical mobile—satellite service. on a secondary basis. provided that Airborne Earth Stations (AES) include specific protection to the Space Research Services (SRS) earth stations and to the Tracking and Data Relay Satellite System (TDRSS) within the 13.40 — 14.4 GHz—band Row 44 has filed an application for license authorization to operate up to 1000 technically identical AES units in the 14.05 — 14.47 GHz—band. The Row44 AESs receive from. and transmit to. the same GSO satellite transponder under control of a Ground Earth Station (GES) and Network Operations Center (NOC). They. and the terrestrial network to which they are connected. comprise the Row 44 system. This Coordination Agreement has been prepared to ensure that operation of the Row44 AESs conform to FCCrequirements for protection of the SRS Network. Row44 has the authority to negotiate and sign this Coordination Agreement for their AMSS system and NASA has the authority to negotiate and sign this agreement for the TDRSS and SRS Network sites listed in Seetion 3. 1.

Obtain the NORAD orbital elements directly at: hitp:~celestrak.com NORAD‘clements: choose Tracking and Data Relay Satellite System (TDRSS) Additional TDRSS Carth Station Sites: NASA shall provide Row 44 at least two months written notice of when the Blossom Point. MD earth station is about to become operational. Protection ofthis site must be provided byits planned operational date ofuse. NASA may unilaterally add additional TDRSS earth station sites to the list in Table | above. NASA will notify Row44 as soon as it knows that a newearth station is being planned and has the coordinates ofthe newly planned site. Earth Site Protection Limits: The TDRSS protection limits are listed in the Table 2 below. Frequency Band Interference Threshold Limit Reference Percentage Measured at Antenna Output of Time 13.40 —— 14.00 GHz —176 dBW/ kHz Never to be Exceeded 14.00 — 14.05 GHz —146 dBW/ MHz Neverto be Exceeded 14.05 — 14.40 GHz —100 dBW Never to be Exceeded Table 2. TDRSS Protection Limits For interference calculations. the TDRSS spacecraft can have an inclination angle up to 15 degrees. In calculating the interference threshold levels in Table 2. the antenna patterns in Figure 1 belowshould be used. The antenna pattern for the Blossom Point site will be similar to the WSC pattern in Figure 1. NASA Coordination Agreement 3 of 3
