43777 Central Station Drive, Suite 360, Ashburn, Virginia 20147 571.281.3570  XTAR.COM STA Request - Narrative STA Confirmation Number: EL653090 STA File Number: 0577-EX-ST-2019 Date of Submission: April 1, 2019 Introduction XTAR requests a Special Temporary Authority (STA), beginning 16 Apr 2019, to operate an X-band satellite communications link in the X-band (7.25-8.4 GHz) frequency range to support RDT&E of a WGS- compatible, remotely-piloted vehicle. This vehicle, once initial benchtesting is completed in April 2019, will be used in WGS-XTAR handoff tests this summer, to be scheduled with US Air Force Space and Missiles Systems Center. A STA is specifically requested due to the need for pre-handoff benchtesting of the vehicle's onboard systems through the commercial X-band SATCOM link, to be provided by XTAR. Benchtesting is scheduled to begin on 16 April to meet summer 2019 WGS-XTAR handoff testing timelines, and will occur periodically over the next 6 months. An extension will be requested if needed. Due to pre-launch international coordination agreements, XTAR does not cause interference with the DoD's Wideband Global SATCOM (WGS) constellation. POC: Lt Col Gary Thompson, USAF Chief, Future Technologies Branch, SMC (310) 653-9748 gary.thompson.17@us.af.mil Network Topology If approved, XTAR will establish a 2 x 4 Mbps TDM/TDMA circuit between a remote terminal located in Fredericksburg, VA and a commercial teleport located in Hamilton, Ontario, using the XTAR-LANT North America (C7) beam as depicted in Figure 1, below. Modem to be utilized is an IDirect Evolution 850. More detailed specifications for this circuit are provided in STA request. Page 1 of 2 XTAR Proprietary and Confidential
