摘要:
A navigation device (16) for surveying and directing a borehole (15) comprises: a first gyro (2) including a first sensitive axis (5) and a second sensitive axis (6); a second gyro (4) including at least a third sensitive axis (7); and a driving unit (9) configured to orient the second gyro (4) in a first mode in a first position in which an earth acceleration (g) dependent error on the second gyro (4) is insignificant and to orient the second gyro (4) in a second mode in a second position in which the third sensitive axis (7) is perpendicular to the first sensitive axis (5) and perpendicular to the second sensitive axis (6).
摘要(中):
用于测量和引导钻孔(15)的导航装置(16)包括:包括第一敏感轴线(5)和第二敏感轴线(6)的第一陀螺仪(2) 包括至少第三感测轴线(7)的第二陀螺仪(4); 以及驱动单元(9),被配置为在第一位置中将第二陀螺仪(4)定向在第二位置,在第一位置,第二陀螺仪(4)上的与地球加速度(g)有关的误差不显着,并且使第二陀螺仪 4)在第二位置,其中第三感测轴线(7)垂直于第一感测轴线(5)并垂直于第二感测轴线(6)。
