Study on North-finding Deviatiun Caused by the Turntable's Periodic Angular Position Error in a Rate Biased RLG North-finder
摘要
Abstract
Currently,the continuous rotary north-finder is widely discussed for its outstanding perfornance.However, few researches about the influence of turntable error on the continuous rotary north-finding algorithm can be found.For the north-finder based on rate biased RLG(ring laser gyro),the influence of turntable's periodic angular position errors to the north-finding results was studied. Theoretical analysis shows that,the existence of periodic angular position errors may cause unexpected error in the north-finding process and these errors must be modeled and compensated for in order to increase the north-finding precision.Finally,simulation and experiments were carried out to verify the theoretical conclusion.关键词
