Abstract
Technologies for tracking and locating underground assets include a survey instrument having an asset tracking device. The asset tracking device determines a current geographic location of the survey instrument and a heading of a sensor group of the survey instrument when aimed at a target measurement point of an underground asset. The asset tracking device measures the distance between the sensor group and the target measurement point of the underground asset. The asset tracking device also determines the pitch of the sensor group when aimed at the target measurement point of the underground asset. The effective height of the sensor group relative to the elevation at the survey location is also determined. The asset tracking device determines the geographic location and a corresponding depth of the target measurement point on the underground asset based on the determined and measured information.
