  1. The National Office for Integrated and Sustained Ocean Observing and Predictionhtttp://www.ocean.us.net Update on the U.S. Department of Defense/U.S. Navy/ Office of Naval Research Program to Implement Advanced Telemetry From Oceanographic Platforms Stephen R. Piotrowicz, Ph.D. 14 October 2002

  2. Program Status • Phase II Contracts Awarded March 2002 • NAL Research – Data Unit System Development • Omnet – Data Delivery Serivices • Distributing 100 L-Band Transceivers • Web Solicitation for Potential Applications • Objective is a Spectrum of Platforms, Environments, and Data Delivery Requirements • Participants Selected in June • Distribution of Conventional Data Units Began in June • Distribution of GPS Capable Units Beginning in October • Distributing 104 Iridium SIM Cards Utilizing the Department of Defense/Defense Information Systems Agency Gateway in Hawaii

  3. Overview of Iridium Satellite LLC • Purchased Iridium LLC for $25 Million • Annual Operating Costs ~$85 Million (Original System ~$1 Billion) • 3 Gateways • Equipment Pricing - $500-$1,500 (Original System - $1,500 - $3,500) • Service Pricing/Minute - $1.00 - $1.50 (1 Rate Globally) • [Original System $2.00 - $7.00 in a 15x15 Matrix] • Commercial Service Launch • Voice: 31 March 2001 • Data: June 2001 • $3 Million per Month from DoD Contract (2 Year; 5 One-Year Options) • Up to 20,000 Subscribers, Unlimited Airtime • Government Handles Tail Charges, Connectivity to Internet, Subscriber Equipment Ordering, Billing, Etc. • Satellite Network and Control Facility Operated by Boeing

  7. Current Status of Iridium

  8. Iridium Gateway D900 Corporate Network Dial-Up Data PSTN ISP • Direct-Dial Connection Between Mobile Application and PSTN (Corporate/ISP) • AT Commands and RS232 Provide the Application Interface to the Subscriber Device • User Throughputs Up To 2,800 bps (nominally 2,400 bps)

  9. Direct-Internet Iridium Gateway Internet Internet Server D900 • Direct Internet Provides a Complete Digital Connection to the Internet - Iridium is the ISP • Reduced Session Set-Up Time and Improved Grade-of-Service Over Dial-Up • Employs SmartConnectTM Features to Support Connection Management • Compression • Spoofing • User Effective Throughput is Nominally 10,000 bps

  10. Short Burst Data Service User Application Iridium Gateway Internet SBM Network Equipment D900 • Short Burst Data is an Efficient Packet-Based Service. • Service is Planned to Support ~1900 bytes in both MO & MT Directions • Pricing plans to be based on per byte usage • Combination of Circuit & Short Burst Data Results in Cost Effective Usage Growth.
