| 1 | 国际地球参考框架的原点显示文摘随着近年来空间大地测量学的不断发展,地球的质量中心(CM)与几何中心(CF)再也不是不可辨别的了。现在,国际地球参考框架(ITRF)原点被确定为CM,显示出相对真实的CM有从几毫米到1cm范围内的季节性变化。由于科学家们研究地球的季节性及短时间尺度的动态形变,并开始把观测的地心运动与地球物理学模型的预测结果进行比较,参考框架显现出了因未考虑地心运动带来的明显误差。本文讨论了ITRF原点的性质,探讨了GPS测量对于地心运动的敏感性。我们发现地心运动的非线性值并没有包含在ITRF中,当前国际地球参考框架原点的特性在长趋势上反映地球的质量中心,但在季节性上反映几何中心。ITRF原点的本质取决于所采纳的运动学模型和无模型的网络运动。现有ITRF的原点应该定义新的术语来精确地反映CM的本质。这样,原点将保持其现有的长期稳定性,从而把季节性时间尺度的原点精度提高到亚毫米级水平。通过1度形变方法,GPS在测定季节和更短时间尺度的地心变化方面具有提供有价值信息的潜能。 | 董大南 T.
