DBCP-O3 Recommended format

(SVP standard drifter format)

This is the Argos message format recommended by the DBCP evaluation group for the so called "Standard SVP drifter", i.e. SST only Lagrangian drifter. It can be used for buoys transmitting 28 bit Argos IDs. See also complete list of DBCP recommended formats.

Please contact Mayra Pazos for details.

Advantages of this format are:



Bits Sensor Description Sampling Calibration
8 Submergence Sea water switch, i.e. drogue detector. 30 minutes observation cycle 5 sec. sampling, cumulated, updated every 30 min.

Immersion time in seconds during the 30 minute period, e.g. time = count*10, or % of time underwater, e.g. %=count*0.555

6 Voltage Battery voltage 15 min. sampling e.g. Bat = count*0.2 Volts
10 SST Sea Surface Temperature 1 min. sampling, averaged and updated every 15 min. Linear, e.g. SST = (-5 + 0.05 * count) Celsius
8 Unused Unused bits (not present in case of 28 bit Argos IDs) Unused bits Forced to zero.
