Explanation

Please explain in the area below why an STA is necessary: Mobile Satellite Ventures Subsidiary LLC (MSV) is licensed to operate a Mobile Satellite Service (MSS) satellite (AMSC-1) in the L-band at 101W. MSV also holds blanket mobile earth terminal (MET) licenses authorizing access to its satellite. MSV seeks to extend its existing experimental STA (Call Sign WB9XVQ; File No. 0424-EX-ST-2003) to test signal processing algorithms used to mitigate co-channel interference. This will entail use of a BPSK-modulated L-band carrier signal that will be transmitted over MSVs AMSC-1 satellite from a ground station in Reston. The data rate and EIRP of this carrier does not fall within the technical parameters authorized under MSV’s existing blanket MET licenses. MSV is requesting only to conduct its test on frequencies it has already coordinated for its satellite system through the international L-band frequency coordination process. MSV seeks an extension of its existing STA for six months. On this date, MSV has also filed for an experimental license for this test as required by Section 5.61(b) of the Commissions rules.

Purpose of Operation

Please explain the purpose of operation:

Testing signal processing algorithms used to mitigate co-channel interference over the AMSC-1 satellite from a ground station in Reston, VA.

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.
