1. CONCLUSIONS An interference study considering all existing, proposed and prior coordinated microwave facilities within the coordination contours of the proposed earth station demonstrates that this site will operate satisfactorily with the common carrier microwave environment. Further, there will be no restrictions of its operation due to interference considerations. Frequency Coordination and Interference Analysis Report 04/12/2019 Page 3 of 11

2. SUMMARY OF RESULTS A number of great circle interference cases were identified during the interference study of the proposed earth station. Each of the cases, which exceeded the interference objective on a line-of-sight basis, was profiled and the propagation losses estimated using NBS TN101 (Revised) techniques. The losses were found to be sufficient to reduce the signal levels to acceptable magnitudes in every case. The SBE coordinator for the region where the earth station is located expressed concern on receive locations that did not appear in the interference study of this site. Atlas Space Operations has agreed to perform joint testing with the SBE coordinator after the earth station has been placed into operation and was granted conditional clearance from the SBE coordinator pending successful results from the proposed testing. No other carriers reported potential interference cases. Frequency Coordination and Interference Analysis Report 04/12/2019 Page 4 of 11
