Abstract

Large net-shape deployable antenna reflectors are currently a perfect configuration type for large satellites, and the shape precision affects the performance of antennas greatly. The calculation of the temperature field is fundamental to an analysis of the shape precision. This paper presents a method for calculating the on-orbit temperature field for large net-shape deployable antennas, and gets the temperature by using a numerical calculation. The results support and give a certain reference for an analysis of its shape precision and the antenna thermal testing design.
