Measurement of Handheld GPS Measurement Accuracy Based on Mathematical Statistics

 Handheld GPS is a GPS satellite positioning, navigation, data acquisition and mapping instruments, with its simple operation, easy to carry, with a certain degree of measurement accuracy, in the oil field wells survey, road inspection, well location navigation, distance Calculation, rough coordinate acquisition and other exploration and development work, has been a very wide range of applications. Based on the theory of mathematical statistics and measurement error, this paper analyzes, processes and calculates the coordinate data collected by handheld GPS, and obtains the positioning accuracy and actual positioning error of handheld GPS receiver, which is the applicable range of handheld GPS Provided a reference.
