利用大地水准面差距确定地心坐标

Determination of Geocentric Coordinate System Using the Geoidal Undulation

    摘要
  • 摘要: 本文利用Rapp 180×180阶解和WGS-72系统的绝对大地水准面差距分别同我国80大地坐标系的相对大地水准面差距相配合推算了平移转换参数。将本文所得结果同国内已有的用天文、大地、重力和卫星多普勒观测资料推算出来的结果相比较,认为当精度约在±10米的范围内两者是符合的。

     

    Abstract: In this paper the Datum-shift parameters are determined using the map of geoidal undulation based on Rapp's 180×180 solution and the computed values of geoidal undulation with respect to WGS-72 system as well as the map of geoidal undulation with respect to local geodetic coordinate system-1980 of our country.The comparison of the results computed in this paper with the result which has been obtained by using the data of astronomical,geodetic,gravimetric and Doppler observations in our country manifest that the both results are consistent with an accuracy of ±10m.
