“…Assuming that the installation error angles between the b iframe and the g-frame are small, the direction cosine matrix C g b i can be approximated as follows [7]: Note that the north seeking system in this paper just uses one gyro and one accelerometer as abovementioned, so the installation error angle which should be compensated is Á z and Á x , Á y are just used for mathematical analysis.…”
