Abstract
A method for determining an elevation of a laser detector assembly includes calculating an estimated elevation of a laser detector assembly based on data from an inertial measurement unit and a detected laser strike. The estimated elevation is then output. A detected elevation of the laser detector assembly is calculated based on the detected laser strike and the detected elevation is output in response to the detected laser strike. The estimated elevation is calculated and output between outputs of detected elevations.
