摘要

The objective of this research is to develop an automatic guidance system based on sensor fusion of a geomagnetic direction sensor (GDS) and a gyroscope. From the first report, it was confirmed that an accurate automatic navigation by a fixed desired heading direction was very difficult because of a temporal and spatial geomagnetic variation and a drift error of a gyroscope. In this study, we proposed the dynamic compensation method against both a geomagnetic warp and a gyro drift by constructing the adaptive guidance system. From the computer simulation, the accuracy of sensor fusion guidance system improved about 70% compared with the GDS alone. To evaluate robustness of the developed system, a field test using the developed guidance system was carried out. From the test, the accuracy and robustness of the guidance system improved by utilizing the proposed sensor fusion method using the GDS and the gyroscope.
