The Data Circuit Data Decoding & Processing Some Useful Services


The data circuit
From your Platform in the Field to your Computer

Platform Observation acquisition (P,T, S..., GPS fixes)

PTT-PMT Transmission of Argos Messages

Satellites Messages + doppler + time

Argos database Messages and locations per satellite pass

Argos database QC Geolocated Observations (time, long, lat, z, P,T, S...)


Example with GPS Positions
GPS position acquisitions Coding in Argos Messages Messages collection by satellites Messages relay to CLS GPS position decoding Distributed & displayed

ARGOS MONITOR : GEO
Page 16

GEO ArgosMonitor. Has the animal I am tracking entered a wintering zone? returned to its nest? crossed a border?

Has my platform entered/left an area of interest?

GEO ArgosMonitor sends you an alarm message when a platform enters or leaves a defined zone.

ARGOS MONITOR : SENSOR
Page 17

Sensor ArgosMonitor. Is the animal still alive (are heart rate, temperature measurements normal)? How is my platform performing (battery level, light sensor, etc.)? Sensor ArgosMonitor can alert users when an unusal/critical value for a particular sensor is reported.

METEOROLOGICAL & OCEAN DATA MIXED WITH ARGOS DATA ?

CLS is thinking of Providing:
Environmental Data in real time (winds, ocean currents, SST, Sea color...) Mixed Data Bank & Data Server Data Viewer on web on local Software Requires Standard Exchange formats
