Exhibit A Lockheed Martin Corp. Earth Station STA Call Sign E050272 October 2010 Description Lockheed Martin Corporation (“Lockheed Martin”) hereby respectfully requests special temporary authority (“STA”) to continue operating its Napa, California earth station (Call Sign E050272) at slight variance from the license for an additional period of 60 days, while efforts continue to remedy the effects of an anomaly that has befallen the spacecraft that hosts the LM- RPS1 satellite. Specifically, Lockheed Martin requests a 60-day extension of the STA now in force for Call Sign E050272 in File No. SES-STA-20100901-01116 (“September STA”). The Galaxy-15 satellite, which is operated by PanAmSat Licensee Corp. (“PLC”) nominally at the 133º W.L. orbital location and is the host platform for LM-RPS1, suffered an anomaly of unknown origin in early April 2010. Since the onset of the anomaly, Lockheed Martin has been able to continue using the Napa earth station to access the LM-RPS1 payload in its intended manner for the provision of radionavigation-satellite service (“RNSS”). To the extent that the space station has moved outside its designated station-keeping box, Lockheed Martin’s operation of the Napa earth station with a few slightly altered transmission parameters takes place under the authority granted in the September STA. PLC has apprised Lockheed Martin that, notwithstanding the ongoing effects of the anomaly that befell Galaxy-15, it expects that continued utilization of the LM-RPS1 satellite by Lockheed Martin will be viable. Lockheed Martin requests authority to continue operating LM- RPS1 under the conditions authorized in the September STA for a period of 60 additional days – or until January 6, 2011. As the satellite continues its very slow drift eastward from the 133º W.L. orbital location, the operational elevation angle of the earth station is now declining. During the 60-day term requested in this STA, the elevation angle from the earth station to the satellite will be at least 38.3º. With respect to other technical transmission parameters Lockheed Martin was conditionally authorized to use in the September STA (see File No. SES-STA-20100901-01116, at Exhibit A, p.1), Lockheed Martin requests that the azimuth range be further extended on the east to 142.3º from the STA eastern limit of 157.8 º under the September STA. With all of the cumulative changes over the last six months, Lockheed Martin determined that it would be appropriate to undertake a frequency coordination for the transmit frequencies under the operational mode of the earth station operating with LM-RPS1 as it drifts eastward. This report, from Comsearch, is included as Attachment 1 to this Exhibit A. The Comsearch report covers a satellite arc that extends to 75º W.L., an elevation angle range of 24.3˚ to 44.3˚ and an azimuth range with an eastern limit that is between 119.8˚ and 197˚. Therefore, the

Report includes the range of elevation angles and eastern azimuth range proposed for operation through January 6, 2011. The report shows no potential interference cases. Lockheed Martin has notified the GPS Wing (operators of the co-frequency GPS system) of the status of the LM-RPS1 satellite, as required. Lockheed Martin confirms that it has coordinated at-variance operations of LM-RPS1 with the GPS Wing for the duration of the requested STA term. Lockheed Martin recognizes and accepts that all operations at variance with its license for Call Sign E050272 are on a non-harmful interference/non-protected basis. Continued use of a viable LM-RPS1 satellite via the Napa earth station by Lockheed Martin is in the public interest. The LM-RPS1/E050272 network is part of a GPS augmentation system that provides the Federal Aviation Administration (the sole customer of Lockheed Martin for LM-RPS1 capacity) with enhanced navigation data that is used in managing the nation’s air traffic and control systems. Any disruption in service that is otherwise viable would cause a serious prejudice to the public and national interests. As long as Lockheed Martin can reliably communicate that information over LM-RPS1 via its Napa earth station without harmfully interfering with any authorized users of the spectrum, it should be allowed to do so. Lockheed Martin remains prepared to submit permanent applications for the modified authority should such submissions be necessary or appropriate following resolution of the anomaly that affected Galaxy-15. Under these circumstances, a 60-day STA is appropriate. See 47 C.F.R. § 25.120(b)(2). 2

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, based upon the restrictions noted in Section 2 (Summary of Results). Frequency Coordination and Interference Analysis Report 05/27/2010 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 most cases. The following companies reported potential great circle interference conflicts that did not meet the objectives on a line-of-sight basis. When over-the-horizon losses and frequency separation are considered on the interfering paths, sufficient losses exist to negate harmful interference from occurring with the transmit-only earth station. The transmit spectrum will be limited to frequencies 6639.27 MHz and 6690.42 MHz. Company None No carriers reported potential interference cases.
