Mobile VSATs An Overview of Ku-Band Mobile Satellite Services

This presentation provides an overview of Ku-Band Mobile Satellite Services, including Earth Stations onboard Vessels (ESVs), Vehicle-Mounted Earth Stations (VMESs), and Aeronautical Mobile-Satellite Service (AMSS). It covers spectrum management aspects, coordination requirements, regulatory status, and technical considerations for mobile VSAT operations.

  1. Mobile VSATsAn Overview of Ku-BandMobile Satellite Services Presentation to NSMA Spectrum Management 2008 May 21, 2008 Carlos M. Nalda Squire, Sanders & Dempsey L.L.P.

  2. Mobile VSATs • Earth Stations onboard Vessels (ESVs) • Vehicle-Mounted Earth Stations (VMESs) • Aeronautical Mobile-Satellite Service (AMSS) Aircraft Earth Stations (AESs) • Many similarities from a spectrum management perspective • Off-axis e.i.r.p. spectral density, pointing accuracy and automatic shut-off requirements • Coordination with co-frequency users • Network control functionality • Regulatory status (co-primary vs. secondary)

  3. Mobile VSATs ESV VMES/LMSS AMSS

  4. Ku-Band ESV Rules • ESV Order released Jan. 6, 2005 (FCC 04-286, IB Docket No. 02-10) • Rules set forth in 47 CFR §25.222 • Co-primary status in 14.0-14.5 GHz (uplink) and 11.7-12.2 GHz (downlink) bands; unprotected use of 10.95-11.2 an 11.45-11.7 GHz (extended Ku-band downlink) • Coordination requirements near NASA TDRSS facilities in 14.0-14.2 GHz and RAS facilities in 14.47-14.5 GHz • Reconsideration Pending • Higher power operations, non-conforming antennas • Pointing error considerations • Resolution 902 minimum distance (125km vs. 300km)

  5. VMES Rulemaking • General Dynamics’ VMES Petition • Petition filed May 24, 2006, NPRM May 15, 2007 (FCC 07-36, IB Docket No. 07-101; ) • Proposes co-primary status in 14.0-14.5 GHz (uplink) and 11.7-12.2 GHz (downlink) bands; unprotected use of 10.95-11.2 an 11.45-11.7 GHz (extended Ku-band downlink) • Coordination requirements near NASA TDRSS facilities in 14.0-14.2 GHz and RAS facilities in 14.47-14.5 GHz • Comment cycle closed; FCC preparing an R&O • Still an opportunity to license LMSS systems on a secondary basis (e.g., Raysat Antenna Systems, LLC)

  6. AMSS Rulemaking • Petition for rulemaking filed July 21, 2003 by Boeing in support of the Connexion system • NPRM released Feb. 9, 2005 (FCC 05-14, IB Docket No. 05-20), comment cycle closed • Connexion ceased commercial operations December 31, 2006; Boeing continues to serve U.S. government customers • Proceeding is dormant, but…. • Additional AMSS licenses issued to ARINC and ViaSat • New players: Row 44, Panasonic Avionics, etc.

  7. Mobile VSAT Issues • Primary technical issue is avoiding interference to traditional Ku-band FSS operations • Requirement to coordinate with other incumbent users of the band (TDRSS and RAS, minimal use by other services) • Commercial vs. experimental licensing • Effect of UTC Petition? • VMES operations along rail lines and roadways • ESV operations along the coast and inland waterways • AMSS operations in certain stages of flight
