Abstract

Managed by NASA Goddard Space Flight Center, the first spacecraft in the latest series of weather satellites for the National Oceanographic and Atmospheric Administration (NOAA), completed thermal vacuum testing in August 2015. Testing of the Geostationary Environmental Operational System satellite (GOES-R) utilized numerous arrays of tubular electrical heaters to simulate orbital environmental heating for thermal balance conditions and for zonal control to achieve protoflight temperatures of the satellite bus and science instruments. This method of environmental simulation is more complicated than the usual IR simulation techniques, such as heater plates, or GN2 / LN2 controlled coldplates and required additional pre-test analysis and engineering testing during the development of the spacecraft test configuration. This paper will summarize the results of those analyses and tests, including flux uniformity, spectral assessment, testing of sink measurement devices, and finally the pre-test predictions for the thermal balance simulations and the protoflight plateaus.
