Design and realization of the integrated electronic system for the Chang’E-3 lunar rover

In order to fulfill the requirement of the rigorous constraints on weight, volume and power, the integrated electronics system (IES) has been firstly developed for the ChangE-3 Lunar Rover. The electronics system of the Lunar Rover has been optimized by the integrated design method for both the hardware and the software. In this paper, we present how the IES was designed and realized from the function composition, design principle and solution, system architecture, detailed realization of hardware/software to the experimental verification and validation. The flight experiment results of the ChangE-3 Lunar Rover showed that the IES has completed the task of the project successfully, in which the integrated electronics system functioned as one of the most crucial subsystem for the Rovers departure from the lander and the surface exploration task. Moreover, it can provide technical reference for the future spacecraft in which the integrated electronics system will be used.
