A new error analysis method is presented via genetic algorithms for high precise heading determination model based on two total positioning stations (TPSs). The method has the ability to search all possible solution space by the genetic operators of elitist model and restrictioa The result of analyzing the error of this model shows that the accuracy of this model is precise enough to meet the need of calibration for navigation systems on ship, and the search space is only 0. 03% of the total search space, and the precision of heading determination is 4" in a general dock.
