The computation implies that the influence of truncation error of up/downwards continuation is about 0.001 m2·s-2, the maximum error is only 0.11 m2·s-2, which can be ignored in CHAMP gravity field recovery. The influence of the reference gravity field error of up/downwards continuation is less than 0.1 m2·s-2 in general, but the maximum error can reach 1.3 m2·s-2. To reduce this error, a high-precision gravity field model should be used in the up/downwards continuation.

计算表明:延拓误差中的截断误差部分影响量级约0.001 m2·s-2,最大误差仅为0.11 m2·s-2,可完全忽略;延拓误差中的参考重力场模型误差影响随参考场选取的不同而有所差异,整体而言小于0.1 m2·s-2,但最大误差可达1.3 m2·s-2,采用高精度的参考重力场模型能大大减小延拓误差影响。
