  2. TODAY’S PRESENTATION • SYSTEM FEATURES AND CAPABILITIES • HOW THEY CAN BE APPLIED • LAUNCH SCHEDULE & PLANNED CONSTELLATION DBCP XX Scientific and Technical Workshop October 18, 2004, Chennai, India

  3. Argos Space Segment NOAA 15 NOAA 16 NOAA 14 NOAA 17 Argos 2 Argos 2 Argos 1 Argos 2 NOAA 12 ADEOS II Argos 1 Argos 2+ NOAA 11 NOAA N (18) Argos 2 Argos 1 (February 2005) DBCP XX Scientific and Technical Workshop October 18, 2004, Chennai, India

  4. ARGOS 3 • HIGH DATA RATE CHANNEL - 4,800 BITS/SEC • TWO-WAY CAPABILITY • HIGHER RCVR SENSITIVITY – MINUS 137dBm • WIDER BANDWIDTH – 110KHz • 12 PROCESSING UNITS • NEW XMTR MODULATION DBCP XX Scientific and Technical Workshop October 18, 2004, Chennai, India

  5. APPLYING THE NEW FEATURES • PROFILING FLOAT • Surface Time Decrease: 10+ Hours 10 minutes • Float Lifetime Extended: Xmit Only During Sat. Pass • Send Complete 75 Level Profile in One Argos Message! • Send 500+ Level Profile in One Satellite Pass! • Lower Power XMTR – Shift Frequency DBCP XX Scientific and Technical Workshop October 18, 2004, Chennai, India

  6. APPLYING THE NEW FEATURES • DRIFTER • Drifter Lifetime Extended • XMIT only when triggered • XMIT only when satellite is overhead • Send More/Different Data • Lower Power XMTR – Shift Frequency DBCP XX Scientific and Technical Workshop October 18, 2004, Chennai, India

  7. APPLYING THE NEW FEATURES • MOORED BUOYS • Send large data sets (TRITON-TAO) • 8 TRITON hourly data sets in one Argos message • 24 data sets in a single satellite pass • Increase lifetime, Use less batteries • XMIT only when satellite is overhead • Reduce redundant transmissions DBCP XX Scientific and Technical Workshop October 18, 2004, Chennai, India
