Research on highly functional guidance and control technology

An overview of the research on highly functional guidance and control system and equipment technologies is presented. Survey and review on fuzzy technology were conducted in the following aspects: (1) evaluation of fuzzy technology applicability to space technology problems; and (2) review on problems and their remedies in fuzzy technology application in space. Research on the following aspects of extensive redundancy control technology was conducted: (1) environment and reliability for redundancy control; (2) detail and examples of application of the conventional redundancy control technologies to the real systems; and (3) future direction of redundancy control review. Fixed point observation was conducted at the known point on the ground using two Global Positioning Systems (GPS's) and fundamental data were acquired on correlation between the GPS satellite layout and azimuth and elevation errors, effects of selectivity and applicability, and differential navigation accuracy. Design, production, and test were conducted on the second trial produced fiber gyros, mostly accomplishing the target performance, and approximate specifications for fiber gyro Inertial Measuring Unit (IMU) and Inertial Reference Unit (IRU) were established.
