Research on Improving the Accuracy of Positioning Data Obtained by GPS Module

With the development of social and economic, for all walks of life, needs for geospatial information have been growing more and more rapidly, GIS\GPS technology have already deeply penetrated into the areas of land resources, logistics and urban management. Therefore, research on improving the accuracy of positioning data, which is obtained by GPS module that is relatively cheaper than measurement type GPS,to make Low-cost products acquiring position information as precise as possible, have high practical value to meet the demands of Low-precision navigation and agricultural Survey.
