Sending Commands to PMTs
Posting commands via ArgosWeb Loading on Sat. Sat Relay to the PMT

PMT Ack to Sat.
PMT Ack on ArgosWeb
Setting Argos-3 in practice DBCP


Managing Transmission

Rendez-vous with satellites
Information on satellite passes is broadcast to all PMTs PMT can anticipate next satellite passes, time & duration

Efficient transmissions, Power saving
Transmission only when satellite is in view


Sending more data

Rendez-vous with satellite plus: · Interactive data Collection (reception ack) · 4.8 kbits/s High Data Rate

Argos-3 on Drifters
DBCP Pilot Program
50 SVPB Buoy Deployment Steering Team chaired by Lucas Centurioni, Scripps 5 Main Buoy Manufacturers Involved Deployment Starting in March 09 (20 1st units)

CO2 Buoy Project with JAMSTEC, JP
Hundreds Units expected 1st Deployment April 2009

Coastal Applications
Pilot projects with Brightwater Manufacturer


Argos-3 on Floats
PMT Integration w. Main Argo Players
APEX: dev. & tests w. UoW & WEBB Research PROVOR: dev. & tests w.Ifremer & Kannad (NKE) OPTIMARE: SOLO: under discussion Field Tests Starting June 09

Argo Pilot Projects
10 Units to be deployed Worldwide w. 3 Units for EuroArgo (Med Sea & North Atlantic) Deployments Starting mid-2009


Argos-3 on Moored Buoys
TRITON Buoys
Jamstec, JP Main Goal: send 10' datasets (~240 kbytes/day) Uses PMT High Data Rate Deployments Planned for summer 09

ICCM buoy for EuroSITES
Meteo & Ocean hourly datasets Deployment 2nd week of February 09 (if weather permits...)

ATLAS Buoys
Starting work with PMEL


Argos-3 on Animals
Integration studies starting with Telonics & Lotech for land animals 3-4 Collars will be tested in the field in 2009 Marine animals: requirements being collected for Argos-4 specifications


Benefits Targeted
Drifters
Extended lifetime Cost Saving Remote Control (CO2 buoys)

Floats
Much Shorter Surfacing Time Larger Data Volumes

Moored Buoys
Larger Data Volumes Remote Control (commands)

Animals
Power Saving Lifetime increase

ARGOS-3 in short: Tough in Harsh Conditions Smart & Delicated when required!!

Spasiba for your Attention


Argos-4 Specifications
Argos 4 = Enhanced Argos 3
Polar and 2 equatorial satellites, goal: 30 mn time response everywhere

Expanded frequency bandwidth -> dedicated channels for low power transmitters
System capacity & processing capability multiplied by ~4 Higher data volume: 140 kbits per pass (50 w. Argos-3) HD Transmission power saving: 3 W instead of 5 W Downlink capability x 3, signal power x 2

Argos-3 PMTs are compatible with a minor software change
