Verification of a space laser communication system’s parts or of component-level, terminal-level, and
system-level performance using ground test and verification devices on the ground before launch is
vital. In this paper, a data communication and management system is proposed, which is an important
part of the ground test and verification devices system and manages the test process and impacts on the
measurement results directly. We improved the existing hardware buses to make up the hardware part,
and also designed the software part. Several typical tests were performed, and the results show that the
maximum time delay is less than 50 ms. The developed data communication and management system is
demonstrated to be a high-performance system which can meet the requirements in our project.
