The principle of the Multi-position Strap-down North Seeking System is introduced. Mathematical model of the system is discussed. The factors that influence the precision are analyzed. In order to fit the curve of sampling data  back-propagation neural network arithmetic is used in data processing. As templates  curve model is saved at database of the VC software. The template matching arithmetic advanced the measure precision of this system. The measure time of the system is shortened within 1 minute  so it can save time for theodolite. 2011 IEEE.
