摘要:Project survey measures usual transform the GPS geodetic height into the normal height instead of fourth level of measurement in highway, railway and water conservancy works. Because of the linear measurement of the region is banded, the compound surfaces are bound to appear a great error. In this paper, GPS leveling point is a curve which put on an elevation as the function, the two proposed to simplify for the one intended to simplify the proposed model of the complex, to simplify and improve the operation speed, thereby improving efficiency, and guarantee the accuracy of the high into GPS. The title uses the one Newton, cubic spline function and the two surface fitting six-parameter method calculated to compare the accuracy of height anomaly with a set of measures data, improved that the method is possible and can be used in the measure of GPS leveling. © 2011 IEEE.
