摘  要:
论述了影响手持式GPS精度的因素,并探讨了如何有效提高手持式GPS精度。着重阐述了空间直角坐标系之间的转换关系,并为实现这一转换进行了实践操作,在转换过程中运用了高斯投影的反变换、大地坐标系与空间直角坐标系之间的转换等诸多理论。成功地解算出了WGS-84坐标系与西安80坐标系之间转换的三参数,并且通过实测检验得到了较高的精度。

摘  要:
The factors influencing the precision of portable GPS are discussed, and how to effectively improve the portable GPS precision is approached. The conversion between space rectangular coordinates is emphatically expatiated, and practical operations on the accomplishment of the conversion were conducted. In the process of conversion, anti-conversion of Goss Projection and the conversion between geographic coordinates and space rectangular coordinates were also applied. The tri-parameter for conversion between WGS-84 coordinate and Xi'an coordinate was successfully worked out, and high precision was acquired through inspections with instruments.
