Data Collection System (DCS)

NSSDCA ID: 1991-032A-03

Mission Name: NOAA 12
Principal Investigator:

Description

The ARGOS Data Location and Collection System (DCS) on NOAA-12 is provided by CNES of France and is designed to meet the meteorological data needs of the United States. The system receives low-duty-cycle transmissions of meteorological observations from free-floating balloons, ocean buoys, other satellites, and fixed ground-based sensor platforms distributed around the globe. The DCS is able to determine platform location using an inverse Doppler technique and is able to acquire data from any place in the world, particularly in the polar regions. These observations are organized on board the spacecraft and retransmitted when the spacecraft comes within range of a command and data acquisition (CDA) station. The ARGOS data is separated from other spacecraft telemetry and relayed to the CNES processing center in Toulouse, France for processing and relay to users. The system operates in 3 bands: 137.77 MHz, 136.77 MHz, and 401.65 MHz. Identical systems are flown on other spacecraft in the TIROS-N/NOAA series. downlinked to Russian and United States receiving stations.
