With the accumulation of high-precision star sensor models year by year, testers have put forward higher requirements for the low degree of automation of the star sensor ground test system, high maintenance costs, and difficulty in centralized management. In this context, it is very important to develop a simple and easy-to-use automated test system for star sensors. This project uses a standard Ethernet interface and a custom communication protocol to study an automated test system to improve test efficiency and quality. Through the python+Flask framework, the React technology of the web front-end and Webpack packaging technology are specific development methods, the Postgresql database storage technology is used, and the front-end interaction method is used to complete the development. The later development efficiency is high, and the maintenance cost is low. This article specifically introduces the principle of the system, functional modules and the design of the database. The results of the system use show that the project basically reached the original design goals and met the basic requirements of the testers. The system has the characteristics of reasonable structure, friendly interface, and easy maintenance.
