摘要：In the vehicle-borne navigation application system of some special fields such as rally, it is necessary to timely calculate the bias navigation with the premise of fast refreshing the maps, which is on an embedded energy-efficient GIS platform with limited resource. An improved arithmetic was put up in this article including simplifying distance formula, using fixed point and integer value to record space position coordinates. At the same time, relative error coming from the improved arithmetic fulfills the requirements of navigation, it is shown that the improved arithmetic is highly effective in speed by theory analysis and test data, meeting with the application requirements of real-time navigation and bias indicator. ?
