There are problems such as a long data acquisition cycle, high test cost, and uncontrollable factors in manual testing for the traditional attitude algorithm verification process. Also, the test can not go through all attitude positions. The design of an automatic attitude test system is proposed, and it can realize the automatic control of the virtual while drilling sensor and the signal acquisition of the main controller. The test consists of static and dynamic measurement methods, the communication with the main controller is realized through RS485, and the data is acquired and then uploaded to the GUI interface of the automated test system. After verification, the system can modify the step length by setting the attitude, completing the attitude's 100% full coverage test, and verifying the attitude acquisition end of the main controller. The interface is simple to operate, and the automation program is high, which can effectively solve the attitude data. The test cycle is long, and the problem of manual error is easy.
