("CapRock"), by way of the underlying application, seeks Commission consideration for a Special Temporary Authority ("STA") to test an earth station at a 29° 49‘ 28.8" N, 93° 57 18.2" W). Pursuant to Section 25.120(a) of the Regulations, in "cireumstances requiring ... temporary use offacilities, request may be made for special temporary authority to install and/or operate new or modified equipment." In addition, according to Section 25.120(b)(4) of the Regulations, the Commission may grant temporary authorization for a period not to exceed 30 days, if the STA request has not been placed on public notice, and an application for regular authority is not contemplated. In the instance case, the STA request has not been placed on public notice and CapRock does not plan to file an application for regular authority. The proposed antenna will be tested and "burned in" for a period of 30 days. An STA under these conditions is contemplated by the Regulations due to "cireumstances requiring ... temporary use offacilities." An application for regular authority is not submitted because this site will be used for testing purposes. Therefore, CapRock respectfully requests an STA for a period not to exceed 30 days. The planned satellite is IS—707 (53.0 degrees West). CapRock believes that the granting of this STA is in the public interest and that delay in the institution of these temporary operations would seriously prejudice the public interest. In order to ensure service, the requested STA date is July 18, 2009. In accordance to Section 25.120(a) of the Regulations, this STA is being filed at least 3 working days prior to the date of proposed operation. An analysis pursuant to Section 25.115(h) is presented below:

Request for Routine Processing of Non—Compliant Antenna The antenna at issue is a C—band Seatel 9797 (2.4m) ("Antenna"). This Antenna does not strictly comply with Section 25.209 of the Regulations. However, according to Section 25.218 of the Regulations, an applicant may request routine processing of an application if it meets the applicable off—axis EIRP envelopes. Furthermore, an application pursuant to Section 25.218 must file the corresponding tables outlined in Section 25.115(h) of the Regulations. Applicant presents below the tables outlined in Section 25.115(h) and therefore requests routine processing of this application.

FREQUENCY COORDINATION AND INTERFERENCE ANALYSIS REPORT TEMPORAY TRANSMIT ONLY EARTH STATION OPERATION DATES: 7/14/2009 —— 01/14/2010 Prepared for CAPROCK COMMUNICATIONS CORP. OCEAN VALIAN, TX Satellite Earth Station Prepared By: COMSEARCH 19700 Janelia Farm Boulevard Ashburn, VA 20147 July 14, 2009 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. 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. There are no unresolved interference cases involving this earth station.
