Explanation
Please explain in the area below why an STA is necessary:
ViaSat, Inc. (ViaSat) respectfully requests EXPEDITED PROCESSING of its request for special temporary authority (STA). ViaSat is scheduled to test a particular mobile earth station antenna that will be installed on U.S. Army helicopters that are being readied for deployment to the Middle East region. The Army Aviation Command & Control Systems (A2C2S) program has adopted ViaSat’s ArcLight Ku band Spread Spectrum technology and has already performed validation testing on a Blackhawk helicopter during late 2006. The final stages of this program require the installation of ArcLight equipment on two helicopters that will be deployed by the 82nd Airborne division as soon as possible. This installation, however, cannot be tested without access to ViaSat’s experimental test site. ViaSat expects to receive a letter to the Commission from A2C2S describing its urgent need to conduct testing using this ViaSat experimental facility. ViaSat will submit this letter separately. The public interest will be served by grant of this STA because ViaSat would be authorized to continue operations of the ArcLight test facility for critical military applications. Please see attached letter.

Purpose of Operation
Please explain the purpose of operation:  Testing mobile earth station antenna that will be installed on U.S. Army helicopters deployed to the Middle East region. ViaSat is scheduled to test a particular mobile earth station antenna that will be installed on U.S. Army helicopters deployed to the Middle East region. ViaSat routinely used the ArcLight test facility to perform acceptance tests for other U.S. government and military users. Please see attached letter.

Certification
Neither the applicant nor any other party to the application is subject to a denial of Federal benefits that includes FCC benefits pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. Section 862, because of a conviction for possession or distribution of a controlled substance. The applicant hereby waives any claim to the use of any particular frequency or electromagnetic spectrum as against the regulatory power of the United States because of the prvious use of the same, whether by license or otherwise, and requests authorization in accordance with this application. (See Section 304 of the Communications Act of 1934, as amended.) The applicant acknowledges that all statements made in this application and attached exhibits are considered material representations, and that all the exhibits part hereof and are incorporated herein as if set out in full in this application; undersigned certifies that all statements in this application are true, complete and correct to the best of his/her knowledge and belief and are made in good faith. Applicant certifies that construction of the station would NOT be an action which is likely to have a significant environmental effect. See the Commission's Rules, 47 CFR1.1301-1.1319.
