Federal Communications Commission Washington, D.C. 20554 pa o6—774 Murch 31, 2006 Mr. Alfed Mamiet Steptoe & Johnson LLP 1330 Connecticut Ave NW Washington, D.C. 20036—1795 CallSign: E050202 File No: SES—LIC—20051018—01424 File No: SES—STA—20051115—01578 Dear Mr. Mamlet: On Octaber 18, 2005, Stratos Offshore Services Company (Stratos)filed the above—captioned application secking a liense to operate a network of Ku—Band earth stations on board vessels (ESV) through a previously lcensed 6—meter fixed earthstationin Scott, Louisiana. Pursuant to Section 25.112(a)(1) ofthe Commission‘s rules, 47 C.FR. § 25.1 12(a)(1), we dismiss the application and the associated requestforspecil temporary authority (STA)as defective. Specifically, for Stratos‘s proposed one—meter ESV antennas (Remote Types #1 and #1), Strats lissthe proposed Maximum EIRP per Carvir(tem E48) as 45.8 dBW for emision designator (item E47) 40OKG7D, This valueis greatethan, and therefore inconsistent with, the Total EIRP for All Carriers(iem E40), which Stratos indicates is 43.5 dBW. Similarly, for the 2.4meter ESV antennas(Remore Type #3), Strato iss the proposed Maximum EIRP per Carier (item E48)as 52.2 dBW for the following emission designators (tem E47): 4M9OG7D, 2MB0G7D, 2M40G7D, IM40G7D and 200KG7D. This is greate than the Total EIRP for All Carrirs (tem E40) which Stratosindicatesis 48.6 dBW. Given these inconsistencies, we cannot determine the proposed emission power. As a result,the application defective, and therefore dismissed While we dismiss the application on the above basis, we take the opportunity to apprise you of other concems we have should Stratos choose o e—file the application. Firs, in Iterms ES7 and ES9 ofthe Schedule B ofthe application, Stratos liss the minimum anterna elevation angle as 0 degree. Section 25.205 ofthe Commission‘s ules, however, sttes that earth station antennas shail not be authorized fotransmission at an angle that is lessthan 5 degrees measured from the horizontal plane to thdirection ofthe maximum radiation: Second, Stratosindicates that ts proposed 1.0 meterand 1.2 meter antennas meet the of—axis EIRP density limits contained in Sections 25.222(a)(1) through (4) ofthe Commission‘s rules, 47 Call Sign Eosorss

Federal Communications Commission pa 06—774 CRR. § 25.222(a)(1)through (4). Stratos appearsto base this assertion on the assumption that the antennas also comply with the anterna radiation performance standards contained in Section 25,209 of the Commission‘s rules, 47 C.FR. § 25.200. Thtechnical showings supplied in other applications folcenses for the same SeaTTel 1.0 and 1.2 meter antennas as Stratos proposes to utlize, indicate that the antennas do not satisfy Section 25,200‘antenna radiation performance standards between 1.25 and 1.5 degrees. Consequentl, Stratos must include, in any refiling, a demonstration of ts of:—axis EIRP density levels beginning at 1.25 degrees of—axis with 0.1 degree increments out to 2.25 degreesofaxis. The demonstration should include a comporison ofth authorized offaxis EIRP density limits specified in Section 25.222(s)(1)—3) ofthe Commission‘s ules Finally, in Attachment C ofthe application, Sratos sttes that .. the antenna controller can detect within 100 milliseconds a pointing error that exceeds 0.5 degrees and ceasetransmissions immedistely...". Strtos must clarfy in any refling whethe the antenna controller can automatically detect and cease transmissions within 100 millseconds of a pointing error that exeeeds .5 degrees, in conformance with Section 25,222(@(7) ofthe Commission‘s rules, 47 CBR§2522200) Accordingly,pursuant to Section 25.112(a)(1)ofthe Commission‘s rules, 47 C.FR. § 25.1 12 (2)(1),and Section 0.261 ofthe Commission‘s ules on delegations ofauthonty, 47 CER. § 0.261, we dismiss both applications as defective without prejudice to refling. Sincerely, Scou er Chiet, Systems Analysis Branch Satelite Division Interational Bureau 547CR §281120)(0) See alo Echost Satellte LLC, Order on Reconsideration, DA 044056 (reeased December 27, 2004)
