| Abstract: | In this paper, the principle of north-seeking by a new-type automatic gyrotheodolite is analyzed. The influence of the geographic latitude on the compensation angle, the appatatus constant and the surveying precision of the gyro is discussed based on a new type of auto gyrotheodolite. In addition, the relation between the surveying precision of the gyro and the change of the geographic latitude is discussed. Some solutions and suggestions to enhance the surveying precision of a gyrotheodolite are proposed. |
