  • In order to obtain accurate, reliable thermal boundary conditions for the thermal design, thermal analysis and thermal tests of space cameras, the transient space heat fluxes of space cameras working in sun-synchronous circle orbits are calculated. The relations of six orbit elements in space orientation of satellites are summarized, and the necessary parameters for the sun-synchronous circle orbit are given. The relative positions between sun vector and orbit, angles are calculated with STK program for the given sun-synchronous circle orbit, thus the upper temperature orbit and lower temperature orbit are oriented. Based on the theory calculation of space heat fluxes and taking some space cameras working in the given orbit as examples, a Finite Element(FE) calculation model for the space fluxes is constructed. Using IDEAS/TMG module, the transient space heat fluxes of upper temperature orbit and lower temperature orbit are calculated particularly. The transient change curves of solar radiation heat fluxes, earth and solar reflection heat fluxes and the earth and infrared radiation heat fluxes in an orbit period are obtained. The calculation results could be taken as input data of space cameras for thermal analysis and the simulation of space heat fluxes in space environment thermal tests.
