【 摘 要 】

To overcome the deviation and develop the signal integrity of inertial technology sensor, a rapid pre-orientation method based on angular detecting was put forward and built the calculating model through analyzing the output characteristics of the miniature FOG north seeking in continuous rotary, which analyzed kinds of factors and improved more precision of advanced north seeking. Firstly, according to the sensitivity of interference, the method was established different filter pretreatment and post-treatment; Then, the output error had been reduced by using high speed acquisition consistent with the inherent frequency of FPGA and DSP; Finally, these experiments datas were designed and conducted to different error factor by the processing nonlinear least square method. Analysis and experiment results showed that the proposed method could achieve north seeking sensor at any initial erecting north angle maximum error can be controlled within 5%.
