COMPARE, a combined sensor system for re-entry missions

For the DLR mission SHEFEX II, the Institute of Space Systems (IRS) proposes a combined sensor system. This experiment combines both pyrometric and radiometric measurement during the re-entry phase. Additionally, total pressure can be measured via the optical path of the radiometer. The experiment will enable a separation of the radiative heat flux from the total heat flux and it will enable the specific enthalpy to be determined. By measuring at adequate wavelength ranges information on plasma composition can be gained.
