Data Reception and Dissemination

The drifting buoys transmit the data via the Argos System and the data are received at the Local Users Terminals (LUTs) in Oslo, Søndre Strømfjord and Toulouse and further disseminated via the GTS.

By utilizing these three LUTs the data reception rate for the EGOS buoys is increased by more than 50%, relative to data reception based on a single LUT.

Furthermore the time-gap with no data received because of the orbit configuration is substantially reduced.

The time-lag between observation and data reception at the operational centre varies considerably. Approximately 90% of all observations are received within 90 minutes with a mean time lag of approximately 30 minutes.

Data retrieval for the moored buoys is via the Meteosat geostationary satellite operated by EUMETSAT.
