摘要
为了减小基座扰动对寻北精度的影响,首先分析了基座扰动引起的寻北误差,推导了基座扰动与寻北误差之间的关系表达式,并提出通过增加隔振基座和选择采样时间来减小基座扰动引起寻北误差的方法,通过卡车振动试验,证明该方法可以较好地减小基座扰动对寻北精度的影响。
In order to reduce influence of pedestal disturbance on north-seeking precision,north-seeking errors caused by pedestal disturbance was analyzed firstly.The relational expression between pedestal disturbance and north-seeking errors was derived.And a method was put forward that north-seeking errors caused by pedestal disturbance was reduced by isolator and selecting sampling time.It was demonstrated that this method can better reduce the north-seeking errors caused by pedestal disturbance affectively by truck vibration test.
