Data Collection System (DCS)

NSSDCA ID: 1988-089A-03

Mission Name: NOAA 11
Principal Investigator:


The Data Collection System (DCS) on NOAA-H is designed to meet the meteorological data needs of the United States and to support the Global Atmospheric Research Program (GARP). 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. These observations are organized on board the spacecraft and retransmitted when the spacecraft comes within range of a command and data acquisition (CDA) station. For free-moving balloons, the Doppler frequency shift of the transmitted signal is observed to calculate the location of the balloons. The DCS is expected, for a moving sensor platform, to have a location accuracy of 5 to 8 km rms, and a velocity accuracy of 1 to 1.6 m/s. This system has the capability of acquiring data from as many as 2000 platforms per day. Identical experiments are flown on other spacecraft in the TIROS-N/NOAA series.
