INS’s Performance Evaluation Methods Based on K Line Theory

By comparing the similarity between stock trend analysis and performance evaluation of inertial navigation system (INS), the feasibility of INS's performance evaluation and prediction of the K line theory is analyzed. The K line and drawing for INS performance evaluation are defined; parts of the K line indexes and their calculation formula are redefined and transplanted. These methods are tested and verified by using simulated and the INS actual data. Analytical results indicate that the K line theory can be evaluated to predict the INS performance and the method is precise and effective. Research results have an important guiding significance to develop INS performance evaluation standards and demonstrate that economic theories can be used in engineering application with a certain internal relations. It would be a promising work which should be further investigated.
