Summary:

AbstractA key element of spacecraft thermal balance testing is the reliable determination of the final temperature values of the temperature equilibrium. At the end of a thermal balance test phase, temperature equilibrium is generally considered to be reached when nearly all thermocouples have fulfilled pre-defined temperature equilibrium criteria, e.g. in the form of a maximal allowed rate of temperature change.Test time can be reduced in the same manner as the equilibrium temperatures can be reliably extrapolated from the measured thermocouples temperatures, thus requiring only a less stringent equilibrium criterion to be fulfilled by the sensed temperatures.This paper concentrates on a mathematical theory for practical use in the extrapolation of equilibrium temperatures for spacecraft and units with essentially radiative couplings to their thermal environment
