In order to ensure that the lunar based extreme ultraviolet camera can finish the engineering task satisfactorily, monitor and research the earth plasmasphere, the software system was designed and implemented. Firstly, the structure and the operating principle of software system were introduced. Then, the key modules and work mode of software system were designed in detail. Finally, the long-term exploration results of extreme ultraviolet camera based on lunar were analyzed in detail. The exploration results indicated that software system could control the extreme ultraviolet camera to track the earth exactly and the control error of tracking mechanism was no larger than 0.1°. In addition, the lunar based extreme ultraviolet camera obtained high quality images when the high-voltage power supplied output 2 850 V and finished all functions and implement the work mode correctly. The performance test results satisfied the requirements of extreme ultraviolet camera technical indexes. The software system plays an important role for extreme ultraviolet camera on-lunar operation.
