Thermal Analysis of Deployable Truss Antenna in Orbit

Using conduction-radiation theory, considering the orbit of the antenna, temperature fields of a deployable truss parabolic antenna in orbit can be calculated at different local time. Using Visual Fortran, a finite element program based on the theory above is built, and temperature fields of antennas in different orbits can be calculated at different local time. The result is useful to thermal displacement analysis and thermal control design.
