Abstract: A system and method for maintaining a laser impinging on a laser detector assembly includes determining a location of the laser from a rotating laser transmitter impinging on a laser sensor. A current position of the laser sensor along a mast of the laser detector assembly is determined and a new position for the laser sensor along the mast is determined based on the location of the laser impinging on the laser sensor and a current position of the laser sensor. The laser sensor is then moved to the new position. The system and method provide an effectively long working range of the laser detector assembly by moving the laser sensor along the mast of the laser detector assembly. An inertial measurement unit is used to calculate position information in the period between laser strikes.
