Mission Name: NOAA 7The Data Collection and Platform Location System (DCPLS) on NOAA 7, also known as ARGOS, was designed and built in France to meet the meteorological data needs of the United States and to support the Global Atmospheric Research Program (GARP). The system received 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. These observations were organized on board the spacecraft and retransmitted when the spacecraft came within range of a command and data acquisition (CDA) station. For free-moving sensor platforms, the Doppler frequency shift of the transmitted signal was observed to calculate the location with a location accuracy of 3 to 5 km rms, and a velocity accuracy of 1 to 1.6 m/s. This system had the capability of acquiring data from as many as 4000 platforms per day. Identical experiments were flown on other spacecraft in the TIROS-N/NOAA series. Processing and dissemination of data were handled by CNES in Toulouse, France.
