ON GNSS POSITIONAL ERROR TRANSFORMATION BETWEEN COMMON COORDINATE SYSTEMS
在常用坐标系下GNSS点位误差转换方法研究

Because the transfer function between the geodetic coordinate system and the Cartesian coordinate system is a multi-implicit function,whose explicit expression is more complex and the unit of the parameters is not uniform in the GNSS positional error conversion.This paper uniformly converts the angle error to length error in geodetic coordinate system by radius of parallel circle and curvature radius of meridian,and the transformation matrix has been derived.The results show that the matrix is not only simple in form but also an orthogonal matrix.
