The low power consumption mode of the instrument is studied, and the design scheme of time calibration by using real-time clock chip is discussed. Through precision test and application examples, it is proved that the trajectory measuring instrument has the characteristics of high precision, low power consumption and small size and can fully meet the requirements of drilling trajectory measurement in actual drilling technology.
