Data Collection System (DCS)

NSSDCA ID: 1980-043A-03

Mission Name: NOAA-B
Principal Investigator:


The Data Collection and Platform Location System (DCS) on NOAA-B was designed to meet the meteorological data needs of the United States and to support the Global Atmospheric Research Program (GARP). The system was to receive 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 to be organized on board the spacecraft and retransmitted when the spacecraft came in range of a Command and Data Acquisition (CDA) station. For free-moving balloons, the doppler frequency shift of the transmitted signal was to be observed to calculate the location of the balloons. The DCS was 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 had the capability of acquiring data from up to 2000 platforms per day. Identical experiments were flown on other spacecraft in the TIROS-N/NOAA series.
